Contamination

Contamination is a boss map in Item Asylum added in version 1.8.0 as part of the Halloween Update.
==Overview==
Contamination is a recreation of a Roblox zombie horror game of the same name created by CoderQwerty (formerly qwerty1806). Just like the original Contamination, the map is a dark, grey facility that mainly consists of tight hallways and small square shaped rooms. 
The original Contamination game has been broken, however a fixed version can be found here. 
==Gameplay==
Similar to Uncertified, this boss is very different from normal bosses. The player has to navigate through sections of the map fighting Zombies up until the boss fight. The players spawn with a makarov by default. However, players can swap their items by picking up weapon boxes found in rooms or inside blue lockers.

After fighting countess rooms, the player arrives to a dark and large enclosed arena. After some time, the light opens and illuminates the arena that has 4 gates and blood on the floor. Then, the Brute busts in the arena by destroying a wall in the middle.

=== In-game dialogue===
==== Upon starting ====
*"Finally, some survivors."
*"I'm trapped in a room, but I think you guys can help me."
*"I have the keycard needed to escape this facility. If you can free me, I'll help y'all escape."
*"I'll guide you to me, looks like there's Zombies in the room ahead, be careful please."
==== First Room ====
*"Look out! They're coming from the side doors!"
==== Elevator Room ====
*"There's another group of zombies, as well as an elevator in the next room."
*"Clear out the zombies, then call the elevator."
==== When clearing all the zombies in Elevator Room ====
*"Good work, now call the elevator."
==== When calling the elevator ====
*"Quick! Get outta there!"
*"The ceiling is about to cave in!"
==== When the ceiling caved in ====
*"Okay, now we gotta find another way for me."
*"OH! You can to get me by the vents!"
*"Though, watch out for the toxic pool. Falling in is the most likely lethal."
==== When Rottwatt spawns ====
*"There's a Rottwatt behind you!"
==== When getting to Acid Room (Cleared all the zombies) ====
*"Good, Now all that's left is go to the next room and-"
*"What the?"
*"Oh no..."
*"What is that?!"
*"Stay back!"
*"Help!"
*"..."
==Tips==
*If playing with other players, keep in mind that other players will block the bullets of any hitscan item fired at them. Spread out to maximize damage output.
*Unlike other bosses with enemy spawns, killing zombies will not heal injured players. Use the environment and the downtime between rooms to heal up before the next encounter.
*The rooms start the timer at 180 seconds, while the brute starts the timer at 480 seconds.
*Recommended weapons to pick up can be:
**ebony and ivory: Modest DPS with access to Demonic Infusion for more damage and Rainstorm to deal with crowds or Riot zombies.
**hyperlaser: Despite its fairly low damage, it is able to hit multiple zombies at once and ignores riot shields due to its projectiles being hitbox-based.
**mad noob's shotgun: Great damage output and crowd control alongside a fast reload that can be cancelled to squeeze out more damage.
**pixel rifle/micro smg/suppressed mac-10: High DPS and a very good sustaining magazine capacity. Pixel rifle can kill multiple zombies in one magazine, micro smg shoots out consistent shots with a very fast reload, and suppressed mac-10 has high dps.
**trench shotgun: Moderately high damage output, Thrust can be useful to kill or push away any nearby zombies (excluding the Tank). Reload is lengthy however.
*Some of these items can be more situational picks, but can be good to pick up in certain circumstances.
**9mm/m1911/pixel gun: Considerable sidegrades to the starting makarov. 9mm provides consistent damage output, the m1911 provides higher damage while needing to reload often, and pixel gun provides something in between while also having a fast reload.
**awp/ssg-08: Possesses high damage, perfectly accurate shots useful for picking dangerous targets, but rather poor in fire rate and reload time.
**hs-010: Rather low damage even with Fuller Auto, but PSI Strike may prove useful to push away any enemies.
**intervention: Very efficient at killing with quickscopes, but requires back-to-back quickscopes to be effective. Quickscope kills may also blind its user.
**makarov: Can also be found in crates, useful if a bad item is picked up. Modest damage output on headshots, but needs to reload often.
**pm9 evil gun: high damage per bullet, just be mindful of the randomized fire rate and somewhat wide spread.
*Weapons that aren't recommended to be used are:
**chicago: Poor overall DPS.
**etymology: Lower overall damage output and reloads often, which also slows down its user.
**mad sheriff: Requires a lengthy reload every time it is fired. Poor at dealing with multiple enemies. Deals enough damage to pick off any pesky Crawlers, but far from reliable beyond that.
**marksman revolver: Requires consistent ricochet shots to deal high damage/crowd control which may be tricky in the enclosed spaces, overall poor damage output otherwise.
**roulette shotgun/realistic mp5: Performance is heavily reliant on RNG to comply.
**zapper: Reliant on constant airshots to deal good damage and reloads often. The upwards knockback may mess up the aim of other players as well.
*Prioritize on killing the Rottwatt, Crawler, and Riot zombies as they can interrupt the players, especially during the bossfight. 
**Rottwatt: If close enough, the Rottwatt will attack you with a ranged shock that stuns you, allowing the swarm to group up on you or possibly kill you at low health. It is best to deal with them first before they can stun anybody.
**Crawler: Despite their low health, they are fast and their third attack will ragdoll whoever is hit. This may cause the player to be swarmed as they become defenseless. As they are the fastest, they are usually the first ones to make it to you.
**Riot: Their shields will block any hitscan bullets and possess a shield bash that can ragdoll hit players. Their right arm is exposed from head on and their bodies are exposed from anywhere else.
*When fighting against the Brute, target the Crawlers and the Rotwatts only, as the brute itself can kill zombies that are too slow using its slam or poison vomit
**Weapons with a fast attack rate can easily take out these crawlers.
**Walk in circles as the brute will target where you previously were, and not where you are going to be.

==Trivia== 
*This, Ithor, matter, trashgang and beta are currently the only bosses that don't have Perfect Run items yet.
*While the Makarov used in this game is from the original Apocalypse Rising, Contamination had a Makarov as one of the possible weapons you can spawn with.
*Similar to ZS, the zombies in this boss (and the actual Contamination game) are based on zombies from Left 4 Dead, with some creative liberties taken.
*Players are able to find upgraded weapons, such as awp, mad noob's shotgun, micro smg, and suppressed mac-10. As a downside, players cannot upgrade the starter weapons, being ssg-08, m1911, 9mm, and pixel gun.
*This is the second boss to restrict people to only one weapon category, the first being boss_clayman.
* PortABoi stated that Contamination will stay after Halloween, this has been stated due to some players thinking it was a Halloween exclusive boss fight.
* While playing solo it is recommended to wait in previous rooms to heal while low, as the doors don't open until approached.
