Xen Teleporter

**Xen Teleporter**s used to take the user to the Xen island from the Facility.

The first version of the Xen Teleporter.

## Description

**Xen Teleporter** objects could be found in the Facility until they got removed with an update. They got updated 2 times and changed their appearances with both updates. The functionality was mostly similar, it used to take the user of the machine to the Xen island.

## Trivia

* The main reason of the removal of these teleporters was the spawn camping done on Xen players.
* Before they got removed, they were very close to the HECU spawn.
* Developers told that these are very likely to come back, but in a different form.
Level System

The **Level System** is a game mechanic that allows players to obtain better weapons or increase their stats through earning enough experience to level up. There are two types of levels, **Global Levels** and **Character Levels**.

## Global Levels

**Global Levels** are a type of level which has XP that can be earned by all teams. Reaching a specific Global Level will unlock a Global Reward. Leveling your Global Level can be done by earning Character XP. Global XP is harder to gain since the required amount of XP to level up is higher than a Character Level's, and also because the amount of Global XP earned is less than the amount of Character XP earned.. Global Levels unlock playable characters in the Xen and Survivor teams.

### **Global Rewards**

## Character Levels

**Character Levels** are a type of level which has XP that can only be earned by a team. Each team has its own Character Level, meaning that leveling up your Character Level will not level up the Character Level for other teams. Character Levels improve stats or unlock skins for its respective team.

## Trivia

To see your total XP and progress for a specific type of level, press the Level box in the sidebar GUI while playing as any team. To view a list of Global Rewards AND Character Rewards, press the XP button in the sidebar GUI to open the list.

Pit Drone

**Pit Drones** are bipedal organisms with 5 replenishable spikes on the alien's forehead.

## Description

The Pit Drone is a Race X Alien with two long pointed arms and 3 spikes protruding on its back. 5 spikes are seen on the Alien's forehead, which the Pit Drone can fire and replenish. Next to the spikes are two eyes, and below the spikes are its mouth.

## In-Game

Pit Drones are faster than most Human classes. They deal 25 damage, which is usually enough to kill a Human in 4 hits. They can also fire spikes at their enemies to deal the same amount of damage. They cannot jump. Currently, they are the only playable Race X alien.

## Strategy (Pit Drone)

Pit Drones are better in groups. Together, they can dish out major damage and kill tough aliens. Alone, they are easy to kill since most Xen creatures have more health than a Pit Drone can handle. If you are still going to play alone, try to look for Headcrabs to gain XP. They have no way to fight back besides jumping at you, which they should use for trying to escape you instead. Try not to get trapped in places that require jumping to get out of. If you see a creature with more than 250 health, then you should leave it alone unless you are in a group. It will be hard to kill it because of your melee cooldown and ranged shot cooldown. Use your spikes to kill enemies who are fleeing. If you need to retreat from a fight, fire your spikes at the enemy while running. This will get them to slow down because they will be trying to dodge the spikes.

## Strategy (Human)

Keep your distance and if a Pit Drone sees you, start walking away from it while still shooting at it. If you see a group of Pit Drones, it is better to hide. Pit Drones have 250 health, so if you have weapons that can deal high damage, use them. Even if the Pit Drone does not see you, you should still keep your distance.

## Strategy (Xen)

Xen creatures are usually able to kill Pit Drones without any trouble. If you see a group of Pit Drones and they are approaching you, try to retreat until you find another Xen creature to fight with. If you are a Headcrab, try to jump to places that Pit Drones cannot reach and where their spikes cannot damage you. If you are a Chumtoad, Fast Headcrab, or Snark, use your mobility to run from Pit Drones. They can kill you easily with their melee attacks. Creatures like Houndeyes, Gonomes, or even Vortigaunts are able to take on a single Pit Drone at once. Bullsquids can easily kill groups of Pit Drones with their tail attack, but it is easier to find another Xen creature to fight with. Alien Controllers can avoid Pit Drones melees attacks but will have to deal with their ranged attacks. Gonarchs, Alien Grunts, and Mr. Friendly can easily kill Pit Drones.

## Abilities

* Attack enemies with sharp arms.
* Fire spikes from forehead.
* Replenish spikes.

### **Controls**

* Left Mouse / Button (Mobile) / Button X (Controller) - Hit
* F Key / Button (Mobile) / R2 Button (Controller) - Fire Spike
* R Key / Button (Mobile) / R1 Button (Controller) - Reload

## Trivia

* Pit Drones are the first Race X creature ever to be added to Headcrab Infection.
Fast Headcrab

The **Fast Headcrab** is a gamepass exclusive Xen that can only be played after purchasing its 189 robux gamepass.

## Statistics

### Damage

Instakill (Against Humans)20 (Against Race X)

## Description

Fast Headcrabs are a subspecies of Headcrab which are capable of moving quickly and leaping far distances. The Fast Headcrab has pointed legs allowing precise movement and sharp landings, and two sets of razor sharp teeth.

## In-Game

The Fast Headcrab is the best type of headcrab there is when it comes to obtaining a host. Its swiftness allows clean getaways and its small size makes it hard to hit. It is faster at leaping and moving than the Standard Headcrab and Poison Headcrab variant. It still makes noises which can still alert Humans, but they usually will not have the time to react, nor will they be able to tell a Fast Headcrab by a Standard Headcrab from its noises alone.

## Strategy (As a Fast Headcrab)

Upon seeing a Human you can charge them and easily take them down. They won't be expecting a Fast Headcrab and even if they do, your speed will surely outmaneuver their reaction time or damage output. Because of how fast you move and how far you leap, it would be hard and difficult to host a human at close distances. Instead, take your chances and leap at them when the time and distance is right.

## Strategy (As a Human)

Fast Headcrabs are fast, but if they fail a leap they have a long cooldown. Use fast firing weapons, like rifles or the M249, to make sure you at least land some hits when the Fast Headcrab is moving. If it fails a jump, you can pursue it for a small window of time and kill it. To ensure that the Fast Headcrab fails a jump, make yourself as unpredictable as possible by moving in different directions.

## Abilities

* They are able to control a player and become a Fast Zombie if they land on a head.
* They are also able to leap and jump to high places.
* With their small size, they can go through vents and hide for safety or for an ambush.
* They can damage Race X Aliens with their leap ability.

### Controls

* Space (Keyboard) / Jump Button (Mobile) / A Button (Controller) - Leap

## Trivia

* They are the first gamepass ever to be added in the game.
Gargantua

The **Gargantua** is a gigantic and dangerous Xen alien.

## Description

The **Gargantua** is a bio-engineered alien that works under the Nihilanth. It is a bipedal creature which is massive in size. Sporting one giant eye and a mouth, it also boasts two large pincers on both arms that shoot out intense flames.

## In-Game

The Gargantua is a NPC that is friendly to Xen and hostile to all other teams. It will incinerate any enemy that gets close and will move towards any enemy nearby.

## Strategy

Do not fight Gargantua as Race X or Survivors. Race X isn't strong enough and if you die as a Survivor it will be hard for you to reach the surface again. Instead, you should play as either HECU or Black Ops to defeat the Gargantua since their spawn is on the surface, which is also where the Gargantua spawns. Survivors and Race X will be killed by HECU or Black Ops if spotted by them, too.

Keep your distance and try to get others to help you kill it. Its large size makes it virtually impossible to miss your shots at. Therefore, use high damaging weapons and switch to different highly damaging weapons instead of reloading so you can constantly deal damage. Keep the strategy up without dying, and you will soon defeat the Gargantua.

## Trivia

* Defeating the Gargantua will award you with the Fancy Headcrab skin.
* When the Gargantua is near Black Ops spawn, a missile from a van will fire at and kill the Gargantua.
* The missile deals 300k damage in total.
* Players will be notified if they haven't dealt enough damages to receive the rewards for killing the Gargantua.
* Players will only receive the reward if they contributed equal to or more than 10% of the damage.
* Gargantua will kill other Xen aliens.

Zombie Elf (2023)

```
Zombie Elves were apart of the 2023 Christmas Event, which you can learn more about here!

```

**Zombie Elves** were enemies encountered during the 2023 Christmas Event. They were the first enemy to spawn, and wielded a large candy cane to club enemies.

## Stats

### Gimmick

Continuously attacks when in reach of player to maximize damage output.

## Description

Zombie Elves are dressed in green and red clothing with a belt on their waist. They wear a pointed hat with green-red stripes and carry a large candy cane. They have long, pointy ears and are controlled by Armored Headcrabs. Their appearance suggests that Zombie Elves are actual elves who are being controlled by Headcrabs.

## Behavior

Zombie Elves will pursue the closest Human. They have pathfinding, which means they cannot be cheesed or easily get stuck on objects unlike other NPCs. They have a slower walkspeed than players, but usually spawn in massive numbers. They are at their most effective when they are able to crowd around players.

When in reach of a human, they will play an animation and attack their target. Although Zombie Elves deal 15 damage, they will continuously attack and can deal even more damage if you are close enough thanks to their low attack cooldown. They will play an animation when killed, and if killed while they are attacking, their attacking animation will interfere with their death animation. They do not move when they attack, so players can incite them to attack, move away, and shoot them without being in any danger of taking damage from the elf.

Skins

**Skins** are cosmetic changes for different teams that change the character's model and sometimes changes their gameplay. There are 3 teams in total that have skins, all of them belonging to the Xen category. In total, there are 9 skins that are unlockable and playable, with only 6 of them offering different gameplay and new possible strategies.

Ammo Box

## In-Game

### Purpose

Adds punishment for wasting ammunition. Makes accuracy and weapon usage more important.

The **Ammo Box** is a useful item that can be found around the map that allows players with weapons to restock ammo. Upon getting closer to it, a prompt will ask players to hold E if they'd like to restock their ammo. If they do, a TF2 pickup sound effect will play and their ammo will be fully restocked. If players walk away from the ammo box, the prompt will disappear.

## Trivia

* Xen and Race X will not see Ammo Box prompts.
* Players who haven't unlocked guns yet can also interact with Ammo Boxes, but they will not receive any ammo.
* Ammo Boxes can be found in every Safe Zone.
Survivors

**Survivors** are humans that were caught in the Black Mesa Incident. Their starting weapon are Crowbars, (formerly Bats), and like the other Survivor classes, they spawn in different locations in the facility.

## Description

Their appearance is dependent on the player's avatar.

## Strategy

If you are new and have no good weapons, your best chance to earn experience is to look for injured enemies or Headcrabs and Headcrab Zombies that you can fight. Stick with other survivors to survive longer and increase your chances of winning a fight. If you are trying to escape the facility the best way to do so is to look for a Security Guard. You can also look for the Keycard, but only one spawns and its location changes whenever someone picks it up.

## Trivia

* Although their team thumbnail is a Black Mesa security guard, they have no affiliation with Black Mesa.
Snark

## Description

Snarks are small, hivemind Xen creatures that are highly territorial. They use swarming as their tactic to kill their enemies and they automatically explode after 20 seconds of being threatened.

## In-Game

Snarks possess many of the qualities that make them so feared as they were in Half-Life. They are hard to hit because they are small, and very fast too. They make the same noises as they originally did, but their appearance is different since their model comes from Half-Life Alyx. Much like the Headcrabs, jumping gives them a boost in speed. Snarks are able to jump without a cooldown, making them even harder to hit if they choose to continuously jump.

## Abilities

* They can bite enemies
* They explode upon death, dealing 23 damage.

### **Controls**

* Left Click / Button (Mobile) / R2 (Controller) - Hit

## Strategy (Snark)

Snarks are nimble little creatures that are hard to kill because of their small size and fast speed. As a Snark, you should use your small stature to avoid bullets and damage. While you do have low damage, you can still chip away enemy health. Keep the enemy from regenerating health by damaging them so that other Xen aliens have an easier time killing them.

## Strategy (Human)

Snarks are very hard to hit thanks to their small size and speed, so your best shot at killing them is by using the Spas shotgun or RPG. If the Snark is jumping while attacking you, you can try to attack it with your Crowbar. If not, and if you do not have a shotgun or explosive weapon, use fast firing weapons to hopefully score a shot on the Snark. Otherwise, you will have to depend on a lucky shot from any other weapon.

## Trivia

* Snarks were added alongside Poison Headcrabs, HECU Medics and HECU Engineers.
Weapons

**Weapons** are an essential element of Headcrab Infection. They allow factions to fight each other and defend themselves from Aliens and other enemy teams. There are many different types of **weapons** in Headcrab Infection.

* Melee
* Pistols
* Rifles
* Submachine Guns
* Shotguns
* Machine Guns
* Sniper Rifles
* Explosives

## Melee Weapons

**Melee Weapons** are weapons that rely on players to be up close to deal damage. They can be used whenever an enemy is too close to properly aim and fire at.

 **Crowbar** |  | A weapon that replaced the Bat. In order to deal damage, enemies must be hit by it up close. The bat deals a small amount of damage (4-24) and makes a sound whenever it hits an enemy

## Pistol

**Pistols** or handguns are small concealable guns that can be used with one hand (Albeit in game, always held with two hands) with small caliber, these can range from Semi-Automatic pistols, to hand cannons, double action revolvers and machine pistols. Some **Pistols** do not deal headshot damage. Helmets also provide protection against headshots.

## Rifles

**Rifles** are long barreled weapons that are intended to be fired from the shoulder. There are many different types of rifles, and in Headcrab Infection 2 different types of Rifles are available.

 C727
Deals 19 damage per successful hit. Deals 28 damage per headshot.

## Submachine Gun

Submachine guns are a type of long gun that, rather using a rifle calibers, uses pistol or handgun calibers. While less powerful then a rifle, they are far more suited for medium and close range combat.

 MP7-S
Deals 24 damage per successful hit. Deals 50 damage per successful headshot.

## Shotgun

**Shotguns** are a type of long gun designed to shoot straight walled rounds called shotshells, which discharge multiple shots.

While reloading, one shell is loaded into the shotgun at a time. The animation can be cancelled by unequipping, and all bullets loaded into the shotgun can be used, meaning that the gun does not have to be fully reloaded in order to fire again.
A total of 18 bullets are in the reserves.
Deals 22~ damage per pellet. Deals upwards of 176 damage if all pellets hit the target.

## Machine Gun

**Machine guns** are long guns meant for long sustained fire using rifle cartridges.

8 damage per body shot, 14 damage per headshot.

## Sniper Rifle

**Sniper Rifles** are a long gun designed for high precision and long range. Sniper Rifles are capable of dealing heavy damage in turn for a small clip size and a low reserve count.

## Explosives

**Explosive weapons** are weapons that fire explosive projectiles. These weapons are capable of killing multiple things at once, and can be very dangerous to use in a close quarters environment.

 RPG
2023 Christmas Event

The Christmas 2023 event was a limited time event where players fought through 19 waves of Xen in order to receive the 2023 Christmas Event badge and the event reward.

Players would have to activate 4 Xen crystals found around the map in order to power Arena Teleporters, which would take them to the Event Arena and start the event. The number of enemies would increase each wave and new types of enemies would be encountered every few waves. Enemies had a high amount of health, which would mean all players in the server would have to participate and work together in order to quickly reach Wave 19. While there was no way to lose the event, you had to deal 15% of the Mechanical Headcrab's health in order to get the event reward.

Barnacle

```
This article is for the NPC **Barnacle** - If you are looking for the playable Xen team, *Barnacle Controller*, please redirect here.

```

The **Barnacle** is a Xen NPC spawned by a Barnacle Controller.

## Description

Barnacles are carnivorous creatures that mold themselves into ceilings in the Black Mesa facility. They have long appendages protruding from its mouth which snares anything that touches it. When something is caught, the Barnacle lifts the ensnared object for the creature to consume it. Once it consumes something, it will begin to digest it, and after a few minutes will release its appendage back to the ground.

## Gameplay

Barnacles are able to ensnare most living things that walk into its tongue. Once something touches the appendage, it will lift the creature into its maw and consume it. From there the entity will instantly die. If a Human gets ensnared, they can be saved by killing the Barnacle before it consumes the player. If humans are ensnared, a unique animation will play and they will be unable to use any Weapons or tools. If a Xen or Race X creature gets ensnared, it will stand completely still. Xen and Race X creatures can still be saved before they die to a Barnacle.

## Strategy (Xen / Race X)

Barnacles are just as dangerous to other Aliens as they are to Humans. If a Barnacle puts you at a disadvantage and you have a way of killing it without getting ensnared, then you should find a way to turn the disadvantage into an advantage and only kill it as a last cause. For example, try to corner the Human and trick them by forcing them to walk towards the Barnacle appendage. This will work better if they are constantly facing you and trying to shoot at you. Headcrabs cannot get ensnared due to their low height unless they jump onto the appendage. If you have no means of killing the Barnacle, then you should find a way around the barnacle.

## Strategy (Humans)

Be aware of your surroundings and look out for Barnacle's appendages in areas where the Barnacle itself cannot be seen. Look for blind spots that leave the Barnacle vulnerable and use a firearm to kill it. If you know there is a Barnacle nearby and you are in a fight, try going to a different room to redirect the fight away from the Barnacle. You can also use the Barnacle to your advantage by tricking aliens to walk into the appendage.

## Trivia

* Barnacles can be killed for XP.
* Xen also earns XP for killing Barnacles.
* Gonarchs and Mr. Friendly cannot be ensnared by the Barnacle.
* Players cannot move or shoot their weapon while ensnared.
* Humans have an unique animation for being ensnared by a Barnacle.
Gonome

**Gonomes** are huge, mutated Headcrab Zombies with improved health, speed, and damage output.

## Description

The Gonome copies the avatar the infected Human originally had. Three new green spheres appear on the Zombie's arm. The clothing the zombie had now has a slight green tint. The entire avatar is now enlarged, and the Headcrab controlling the Human is enlarged, too.

## In-Game

The Gonome is a fast Xen Alien that can deal high damage in a short time. It can be obtained only by playing as a Headcrab Zombie for 150 seconds. After which, the Headcrab Zombie will collapse and start to grow. After around 20 seconds, the zombie will rise and become a Gonome. Gonomes can eat 35 flesh to become a Mr. Friendly. Gonomes can collect flesh by consuming dead human bodies.

### **Controls**

* Left Click / Tap Screen (Mobile) / R2 (Controller) - Claw

## Strategy (Gonome)

You retain all previous abilities that the normal Headcrab Zombie had, but you are now faster, deal more damage, and have more health. Use this to rush enemies from behind when they are not looking, making them vulnerable for a short time. This will take them by surprise, and you will have many chances to deal damage. You can also lead groups of Xens with your speed and high health. The health allows you to survive for a longer time. The speed allows you to recon areas and map the layout of the facility. If you are losing a battle, you can always retreat. Your high speed allows you to swiftly move away from the fight and retreat.

## Strategy (Human)

Gonomes are hard to kill because of their speed and health. Don't let it get close to you, and shoot it with high firepower weapons like the deagle or colt python. If the Gonome retreats, pursue it and kill it before it starts to regenerate health unless it retreats into a group of enemies. The Gonome can evolve into a Mr. Friendly if left alive for too long.

## Trivia

* Out of all other zombies, Gonomes possess the most health and damage.

Baby Headcrab

**Baby Headcrabs** are newborn Headcrabs spawned from Gonarchs.

## Description

Baby Headcrabs are white, mini Headcrabs that have not fully grown their teeth or beaks. Their small size and versatility of their legs allows for fast movement and makes the headcrab a tough target to shoot at.

## Gameplay

Baby Headcrabs are somewhat similar to Snarks, with the ability to lunge forward high and far distances. They have a very fast base speed and a very powerful lunge boost, which is balanced with a low damage stat. Out of all headcrabs, they have the fastest recharge of their jump ability and are the fastest headcrab.

Baby Headcrabs can be spawned when a Gonarch is alive and when a player chooses to be a Baby Headcrab. When a Gonarch is alive, a prompt at the bottom left of the screen appears which allows players to become a Baby Headcrab. Players can hide the prompt by clicking a large X on the prompt. Players can also turn the prompt off permanently through their settings. They can turn this prompt back on at anytime.

If 2 minutes has passed, and the user is still alive and playing as a Baby Headcrab, then the user will mature into a full grown Headcrab.

## Strategy (Human)

Baby Headcrabs are very hard to kill. Their small size and fast speed make them hard to accurately hit. Therefore, it is best to use weapons which produce an explosion to have a better chance at killing the headcrab. If unable to, you should try your best to ignore it, only attacking if you have a good chance of killing it.

## Strategy (Baby Headcrab)

You are very similar to a Snark. Try your best to annoy humans - by attacking them and avoiding their bullets. This will distract them and leave them vulnerable to any other aliens that might encounter them. Use your low damage to prevent humans from healing. The healing process is always interrupted after taking damage, so try your best to keep their health vulnerable.
Vortigaunt

**Vortigaunts** are a free-to-play Xen team in Headcrab Infection.

## Description

They are humanoid aliens that are slaves for the Nihilanth, the leader of Xen that invaded Earth. **Vortigaunts** can fire green lightning-like bolts that damages anything that touches it. They will also attack anything that gets too close with their hands or attack by kicking with their legs.

## Gameplay

Vortigaunts are capable of ranged attacks and melee attacks. They spawn in Xen next to the Alien Grunt and Alien Controller spawns. They possess a good amount of health and have the same walkspeed as a Human. Their ranged ability allows Vortigaunts to play as a support role in combat.

## Abilities

* They can fire green lightning-like bolts that act as a ranged weapon.
* They can attack any enemies by hitting them.
* There is an 1/6 chance that a melee attack will replaced by a kick instead of a normal hit. This is slightly more damaging than the normal hit ability.

### **Controls**

* F Key / Button (Mobile) / R2 (Controller) - Energy Beam
* Left Mouse / Button (Mobile) / Button X (Controller)

## Strategy (Vortigaunt)

You have a powerful ability to fire electricity from your fingers. You can also attack anything that gets close by hitting it or kicking it. This lets you fight upfront or from a far place. If you fight upfront, use your melee abilities to chip away health and kill enemies. If they flee, use your electricity ability to damage or kill them. If you take more damage, retreat and take cover, firing electricity to kill them or to force them to retreat too. You can also play a support role if you choose to group up with other aliens, using your ranged attack to deal massive damage that will win the fight for your team. If you are fighting a Pit Drone, it would be wise to attack with ranged attacks and focus on melee when they are close enough because of their speed and attack damage.

## Strategy (Human)

Used ranged Weapons to kill the Vortigaunt. If the Vortigaunt charges up a ranged attack, zigzag and jump to make it harder for the beam to injure you. The closer you are, the easier it is for the Vortigaunt to hit you with the ranged attack. The Vortigaunt can also use melee attacks that have a short cooldown to kill you if you get too close. The best way to protect yourself from a Vortigaunt is to find cover. The beam cannot go through solid objects, and after the Vortigaunt fires you can get out of cover to shoot at it.

## Trivia

* They are one of 2 Xen creatures that possess a natural ranged attack
* They were added after Houndeyes
* You can play voice lines for the Vortigaunt by sending a message in chat while playing as a Vortigaunt.

Poison Headcrab

## Statistics

### Damage

Instant Kill (If it successfully jumps on a unprotected human head.)ㅤㅤㅤㅤㅤㅤㅤ50 damage (To Race X)

## Description

**Poison Headcrabs** are a Xen species that can be unlocked by purchasing its gamepass. Like Headcrabs, they are a parasite that controls their victims by latching onto their head and manipulating the brain.

## Gameplay

Poison Headcrabs are a slower, but tankier version of their normal counterpart. They have a slower jump boost and make a different noise when lunging. While idle, the Poison Headcrab makes a breathing motion. The Poison Headcrab has dark skin with needle-like bristles protruding from itself. Once a Poison Headcrab successfully latches onto a victim, they will begin to assimilate their host and transform into a Poison Zombie.

## Abilities

* They are able to control a player and become a Poison Zombie if they can land on a Human's head.
* They can give themselves a small jump boost by jumping.
* Thanks to their small size, they can enter the vents found around the facility.

### **Controls**

* Space / Esc - Jump
* WASD / Up and Down Arrows - Movement

## Strategy (Headcrab)

As a Poison Headcrab, you can only jump, walk, and latch onto humans. You have high health and a smaller jump boost. This makes the Poison Headcrab most effective in close-space environments. When taking into account the normal Headcrabs' high jump boost and speed boost when lunging, and the close quarters inside black mesa, the Poison Headcrabs' reduced stats is a blessing in disguise. That being said, when trying to assimilate players, go for an ambush approach. Be aware of the long cooldown after jumping, as if you miss a jump you will be very vulnerable until the cooldown is over.

## Strategy (Human)

Poison Headcrabs may be a bit harder to kill than Standard Headcrabs, but they possess no movement speed. Bait them to an open area and keep your distance. Use strong weapons to kill them quickly. If they land a hit you may get infected or damaged. If you can bait them into missing a jump, you can rush and kill them. If you are in a fight and you see a poison headcrab, you should keep your distance and be wary of the Poison Headcrab. If possible, lead the fight away from the Poison Headcrab.

## Trivia

* Poison Headcrabs are the slowest headcrabs in the game
* Poison Headcrabs are the third headcrabs to be added to the game.
* Poison Headcrabs were added alongside Snarks, Medics and Engineers.
Research Samples

**Research Samples** were decorations in the old Headcrab Infection map.

The Headcrab research sample

## Description

**Research Samples** had two forms, one with a Headcrab and one with a Bullsquid. These were samples which were used for a research project conducted in the facility. These research samples got removed after an update that introduced a new map.
Safe Zones

**Safe Zones** are areas exclusive to Survivors, Scientists, and Security Guards. Their purpose is to prevent the spawnkilling of said teams.

## Safe Zones

The interior of a safe zone in the lower levels of the facility.

## Section Header

### Mechanic

Divides a section of the facility into a spawn room and the facility. Players outside of the safe zone cannot enter. Players inside can leave upon accepting a prompt which asks them if they are ready to leave.

### Purpose

Prevent spawnkilling of Survivors, Scientists, and Security Guards.

Safe Zones are randomly generated sections of the map. The purpose they serve is to limit the spawnkilling of players. The safe zone is marked by a transparent, long red wall that cannot be walked through. The only way to leave a safe zone is to interact with a proximity prompt that comes up when approaching the safe zone. After leaving a safe zone, it is impossible to renter it. The only way to enter a safe zone is to die or reset as a Black Mesa team. Safe Zone barriers will kill specific aliens if they touch the red barrier. Survivors can shoot through the Safe Zone barrier.

## Trivia

* In the original version of the game humans could reenter the safe zone.
Alien Controller

**Alien Controllers** are Xen Aliens that operate under the Nihilanth's interests.

## Description

Alien Controllers are highly intelligent Xen creatures. They cannot walk and rely on their ability to levitate. Their appearance is similar to the Nihilanth, with an example being a third arm protruding from the chest. They have 2 vestigial legs and 2 arms that are used for the handling of objects. Their 2 arms are also essential for combat, and it allows them to summon a ball of energy, aim it, and fire it at enemies.

## In-Game

Alien Controllers are Xen creatures that rely on ranged attacks. They are the only playable Xen team that can fly, and can only be played after achieving Level 120 in Global Rewards.

## Abilities

* Alien Controllers possess the ability to levitate in the air.
* Alien Controllers can summon a ball of energy and fire it at enemies.

### Controls

* (WASD) / Dpad (Mobile) / (L)(R) [Controller] - Movement
* F Key / Button (Mobile) / R2 (Controller) - Fire

## Strategy (Human)

Alien Controllers are unique in that they do not move the same way as other Xen aliens. This makes predicting its movement slightly harder than usual. Alien Controllers can also retreat to hard-to-reach places. These factors mean that when trying to kill an Alien Controller, you must do so quickly. Catch it by surprise and do not let it retreat. Alien Controllers rely on ranged attacks, so strafe when its tries to attack you. This will make it miss its attacks, and you will survive longer in combat.

## Strategy (Alien Controller)

Alien Controllers are unique in that they do not move the same way as other Xen aliens. So, use it to your advantage: Move up, down, left, right, or two directions at the same time. Your greatest strength will be unpredictability. If you are close to dying, you can retreat to hard-to-reach places and fire at your enemies from there. You can move to the top of shelfs or high places. When attacking enemies, predict their movements. If they are strafing, it might be wise to move around them and fire at their side. If they are jumping, you can move above them and try to follow them while shooting energy balls.
Xen Tree

**Xen Trees** are a common type of Xen plant that will attack anything that disturbs it.

## Description

**Xen Trees** are one of several plants in Xen. They are unique and can only be found in Xen, and are hostile to everything around it. The sharp limb that the trees possesses is controlled by the tree, and can easily kill anything it comes across. It is not recommended to go near the trees, because even though they only deal 25 damage, they attack very fast. This means that a Xen Tree can turn 25 damage into 100 in just 3 seconds.

## Trivia

* Unlike in the actual Half Life game, you cannot force a Xen Tree to attack by damaging it.
Bullsquid

**Bullsquids** are bipedal amphibians capable of shooting acidic phlegm from their mouths.

## Statistics

### Health

650

Bullsquids appear as large, two-legged carnivores with a squid-like mouth. Bullsquids have thick tails, pure red eyes, and a pattern on their skin resembling leopard's.

## In-Game

Bullsquids are tanky, dangerous Xen aliens. They are faster than humans and have several skins with different abilities. Bullsquids also have their own abilities which allow it to deal AoE damage and ranged attacks.

## Abilities

* Bullsquids can attack players with by biting them with their mouths. When activating this animation, an animation and sound plays that show the Bullsquid using its tentacles to grasp anything close to it, and moving its head in a way where anything caught would get injured from the fast and abrupt movement.
* Bullsquids can also use their tails to whip everything nearby it. This causes anything in its ranged to take damage, besides other Xen creatures.
* Bullsquids can spit out acidic phlegm to damage anything far away from it.

### **Controls**

* Left Mouse Click / Button (Mobile) / R2 (Controllers) - "Hit" attack
* R key / Button (Mobile) / L2 (Controllers) - Tail attack
* F Key / Button (Mobile) / Button X (Controllers) - "Toxic Spit"

## Strategies (As Bullsquid)

Bullsquids are tanky and move at a good speed. Bullsquids also have a ranged attack that deals 30 damage, and melee attacks that deals more damage. This leaves many different playstyles for the Bullsquid.

Bullsquids have the option to group up with other Xen creatures and tank damage, since its health is more than some Xens. You can always do more damage in groups, so try to find some players to group up with. If you can't, you'll be fine playing solo. Your tail attack allows you to deal damage to everybody nearby, meaning taking on groups of humans will be easier. Your ranged attack also creates room for some new strategies. You can choose to find a place of cover and shoot phlegm while hiding behind the cover while it recharges. Anyone who tries to get close to you will be damaged by your melee attacks. Additionally, if somebody is running away from you, you can shoot phlegm at them to hopefully kill them. If someone tries to bait you out of your cover, wait for them to get close then quickly reveal yourself and shoot out phlegm. After you shoot your phlegm, quickly hide back to cover.

## Strategies (As Human)

When fighting a Bullsquid, it is important to know that fighting up close and fighting from a distance will both be hard. When fighting up close, keep some distance between attacks so you don't get hit or get whacked by the tail. If you're fighting in groups, keep everyone seperated and at different distances so they all don't get hit at the same time. If fighting alone and from far away, keep your movement sporadic and unpredictable so it is more unlikely you will get hit by phlegm.
Chumtoad

**Chumtoads** are small Xen creatures that are able to bite hard on enemies to deal damage.

## Description

The Chumtoad is a small frog-like creature with one eye in the middle of its front face. The alien has 3 spikes on its back and 4 limbs which help it move and jump.

## In-Game

Chumtoads will spawn as one of four skins. Unlike other teams with skins, players cannot choose their Chumtoad's appearance. Chumtoads are slightly faster than the average walking speed of Humans and their size is slightly smaller than Headcrabs. Their small size and fast walkspeed makes them hard to kill. Chumtoads have one ability which is named "Hit". This ability lets them deal damage to enemies and it has a low cooldown rate. In order to play as a Chumtoad, you need to be Global Level 50.

## Abilities

* They can attack others by biting. When this ability is used a harsh biting sound will play.

### **Controls**

* Left Click / Tap Screen (Mobile) / R2 (Controller) - Hit

## Strategy (As Chumtoad)

You can deal high damage, are slightly faster than humans, and your small size makes it harder for you to get hit. You can also jump high to reach high places and to reach humans. These abilities allow different playstyles for the Chumtoad team. If you are attacking humans directly by yourself, then you should use your small size and zigzag to make yourself a hard target. If you are still being shot at you can try jumping to throw off their aim. Once you reach a human you can begin attacking and moving in circles around their hitbox. You are faster than humans, so anybody who tries to run can still be killed by you. Another way you can reliably get kills is by joining fights between other Xen creatures and humans. It will be harder to notice you because of your small size, so joining a fight will help you get easy kills. Your attack noise may alert them, however.

## Strategy (As Human)

Chumtoads are hard to spot and can deal massive damage if you aren't paying attention. That said, if you hear the Chumtoad's attack sound, you should keep an eye out for it. If you see it, use weapons with a high rate of fire like the M249 or Weapons that have a wide damage radius like the RPG. If you are being attacked by the Chumtoad, use a crowbar to attack it at close range while jumping continuously to avoid damage.

## Description

HECU Engineers are a subunit of the Hazardous Environment Combat Unit, a fictitious special marines force that was deployed to the Black Mesa Facility during the Resonance Cascade. HECU Engineers are outfitted with goggles to protect their eyes while they breach doors using a welding torch, and a canister on the back that provides fuel for the welding torch. They have the same outfit as all the other marines with a few design changes in their equipment and vests.

## In-Game

HECU Engineers, like all other Marines are given the MP5 as a starting weapon. The MP5 is a unique weapon that is only available to the HECU team. Engineers also carry a unique, team-specific gadget named "Turret\_Blueprint". This tool allows the Engineer to change its rotation and spawn a turret wherever the Engineer pleases.

## Turret Controls

The Engineer can lock a turret in a spot by hovering over its intended spot with the mouse and clicking, or by pressing anywhere using mobile. Then, use the Rotate Turret option to change which direction the turret faces, and press "Spawn" to create the turret. The HECU Engineer may create a new turret at anytime, but if the previous turret still exists, the old turret will despawn after the new one is placed.

Gonarch

The **Gonarch** is a giant Headcrab that can be played by purchasing a gamepass.

## Description

The Gonarch is a powerful gigantic Headcrab, protecting by a shell covering its upper body, and four gigantic spider-like legs, allowing it to move quickly. The Gonarch has a reproductive system named a "sack" which produces Baby Headcrabs. While they are not dangerous on their own, they are very hard to hit and will evolve quickly into headcrabs.

## In-Game

The Gonarch is a slow moving giant headcrab. Because of its large size and the small size of the Black Mesa Facility, its body can clip through doorways to move around the map. It deals massive damage but has a slow attack speed of 8 seconds. Its high health and slow attack speed makes this Xen best suited for tanking damage and protecting Xen.

The Gonarch is also able to spawn Baby Headcrabs. Baby Headcrabs are small undeveloped headcrabs that cannot take over a host yet. If you die fighting a human and the Gonarch is near to that human, you can spawn as a Baby Headcrab to immediately start attacking them again.

## Abilities

* Gonarchs can impale enemies with their legs.

### **Controls**

* F (Keyboard) / Button (Mobile) / R2 (Controller) - "Hit" attack.

## Strategy (Gonarch)

The Gonarch is a tanky, slow Xen that can spawn minions to aid it in battle. It can kill anything relatively quickly, and its tanky health makes its enemies have trouble defeating it. Your best strategy as Gonarch is to roam the facility looking for humans. Overwhelm them with your baby headcrabs, or endure their damage and chase them until they run into a dead end.

## Strategy (Human)

Gonarchs are extremely powerful. Because of their tanky health, and their high damage, they should be avoided. This Xen is the most powerful, and if you see one you should hide and hope that it did not see you. If you get into a fight with a Gonarch, make sure you have allies on all sides to help you kill it. Its slow speed lets you keep a good distance, but it can pursue you to a closed space if it chases you for long enough. If you are alone, run to an elevator and close the door before it can get to you. You are very unlikely to win a fight against a Gonarch alone.

## Trivia

* Poison Headcrab Zombies and the **Gonarch** are the only playable characters that can spawn NPCs.
