## Gun Turret

### Basic:

*Summon a gun turret to provide fire support. Up to 3 turrets can exist at the same time.*

### Skill Upgrade:

**Gun turrets shoot out missiles that have a chance to burn enemies.**

### Mentor Upgrade:

**Turrets' missiles now become rockets.**

### Cooldown:

9 (7) seconds.

Basic
*Summon a gun turret to provide fire support. Up to 3 turrets can exist at the same time.*
* Engineer deploys a turret at his standing point. The turret cannot move.
	+ The gun turret has 12 health. It will be destroyed after 10 seconds or after its health is depleted.
	+ The turret will fire bursts of 12 bullets at the nearest enemy over 2 seconds, and then pause for 1 second before firing the next burst.
	+ Fire rate modifiers such as ,  Fire Rate Buff, or  Coffee only affect the turret attack speed during the 2-second burst fire. They cannot shorten the 1 second pause between bursts.
	+ Each bullet deals 2 damage, with 0 critical chance () and 8 inaccuracy ().
	+ The turret can find targets behind breakable crates, but not unbreakable objects.
	+ There can be up to 3 turrets at a time. If another is built, the oldest one is instantly destroyed.
* This skill has a cooldown of 9 (7) seconds.
* Gun Turret can be further enhanced when paired with the following buffs:
	+ - Makes turrets fire 18 bullets over 3 seconds (instead of 12 bullets over 2 seconds).
	+ - Increase turret's damage by 1, and increases its fire rate.
	+ - Reuses missing bullets.

Skill Upgrade
*Gun turrets shoot out missiles that have a chance to burn enemies.*
* For every 1 second, the turret also shoots a homing missile that flies slower than the bullet.
* This missile can create a small explosion that deals 4 damage and can cause Burn.

Mentor Upgrade
*Turrets' missiles now become rockets.*
* Fires bigger missiles with a much larger blast radius. The rockets are launched at higher velocity but lose their homing effect.
* Turrets emit particle effects similar to a champion but in dark blue. This only serves as cosmetic.

## Armor Mount

### Basic:

*Temporarily equipped with an armor mount. (Applies to solo mode only) You're equipped with the armor mount parked in robotic facility.*

### Mentor Upgrade:

**Armor mount explodes when destroyed, dealing 60 damage.**

### Cooldown:

14 (12) seconds.

How to unlock
Pay $1.99 to unlock this skill.
Basics
*Temporarily equipped with an armor mount. (Applies to solo mode only) You're equipped with the armor mount parked in robotic facility.*
* Despite the description, it is possible to be equipped with the armor mount parked in the Robotics Facility in multiplayer mode.
* Equips the Engineer with an Armor Mount that has 8 Health. The mount is the same as the one currently in the Robotics Facility, or a Prototype Armor if there isn't any.
	+ Defense is equal to that of the equipped mount, which is also affected by Badass Mode's 1 Defense increase.
		- Prototype Armor, the default one for this skill, has 1 Defense (2 in Badass).
	+ The armor mount loses 1 health per second.
	+ The armor mount will be destroyed if all of its HP is depleted.
	+ It is impossible to dismount while the skill is active.
	+ If this skill summons a Prototype Armor, the "Self Destruct" attack can only deal 50 damage as opposed to the regular 199 damage.
	+ The armor mount has no walking speed penalties unlike regular armor.
	+ The armor mount does not have an upgraded weapon, nor will it ever have one.
* - Increases the armor mount's HP by 50% (rounded down), however, the increase is based on the Mount used, not on the skill's HP itself.

 WiFi Booster | 8

* Robo affects this skill, giving the armor mount +2 HP.
* This skill has a cooldown of 14 (12) seconds, and it starts after the armor is destroyed.

Skill Upgrade
*Armor mount lasts longer.*
* The summoned armor mount will have 12 Health instead of 8.

Mentor Upgrade
*Armor mount explodes when destroyed, dealing 60 damage.*

## Interceptor

### Basic:

*Build a laser turret to intercept enemy bullets, or attack enemies if no bullet is in its range.*

### Mentor Upgrade:

**The interceptor can shoot 2 lasers at the same time.**

### Cooldown:

9 (7) seconds.

How to unlock
Pay $1.99 to unlock this skill.
Basics
*Build a laser turret to intercept enemy bullets, or attack enemies if no bullet is in its range.*
* Similarly to his Gun Turret ability, upon activation, the Engineer deploys a stationary turret at his standing point.
	+ Interceptor has 15 health. It will be destroyed after 10 seconds or after its health is depleted.
	+ The turret appears to prioritize destroying projectiles over attacking enemies.
	+ When enemies' projectiles are within a 6-tile radius of the turret, it rapidly fires small lasers to destroy them at the rate of 5 lasers per second.
	+ The turret also fires lasers that deal 3 damage at enemies within a 7-tile radius, with approximately 0.75 seconds of cooldown before it can fire again.
	+ Unlike most other laser weapons, the turret's lasers only reach far enough to hit their target and do not travel any further.
	+ Unlike the Gun Turret, the Interceptor has an indefinite limit of turrets. The only limitation is their expiration time of 10 seconds.
* This skill has a cooldown of 9 (7) seconds.
* Interceptor can be further enhanced when paired with the following buffs:
	+ - Increases laser's damage by 1.
	+ - Reflects intercepted projectiles.
	+ - Increase turret's laser damage by 1, and increases its fire rate(?).

## Trivia

* Before Update 1.3.0, the buff gained at level 6 was Pet Buff.
	+ This was later replaced by Fire Buff, and the Pet Buff was given to the Druid.
* During Update 1.5.0, the Engineer himself and the turret were seen wearing Christmas caps.
* During Update 1.7.0, the turret also had an aiming line. However, it was glitched that it always targeted in a fixed direction.
* Since Update 1.8.2, the Engineer can repair the Damaged Robot for 20 Batteries and 20 Parts. Once repaired, the Robot will be permanently unlocked as a playable character.
* Before Update 1.8.2, the skill icon of Gun Turret featured a green turret instead.
* Before Update 2.0.5, the Engineer could only summon one turret at a time. Activating the skill while the turret is still active would terminate it, and the skill's CD would not start before the turret was destroyed.
* In some Chinese versions of 2.0.5, the "Musician" skin is known as "投币式乐队机器人#1" (*"Musician Coinbot #1"*).
	+ A glitched version of this skin carries his usual pump machine instead of a guitar.
* The Armor Mount skill was added in Update 2.2.0.
	+ Since this update, Engineer can repair the Wrecked Motorcycle for 15 Parts, 15 Ironstone and 10 Organic Matter.
* Interceptor was added in Update 2.7.0.
* The bullets of the Gun Turret skill were somehow not affected by the Weapon Boost, while the missiles were. But after an unknown Update, possibly Update 2.7.0, this issue was fixed.
* Before Update 2.8.0, the Engineer would give the player a random weapon when interacted with during a run, the quotes were also different.
	+ The weapon given was equal to a blue chest in the same floor.
* Before Update 2.8.7, the armor mount was fixed to Prototype Armor in Multiplayer, even if other armor was present in the Robotics Facility.
* In Update 3.0.0, Engineer's default, Hello World and Ruler Huang Tian skins received a retexture.
	+ In Update 3.1.0, Engineer's Heavily Modded, Prototype, Sky Lantern, Poached Egg, Musician, Floating Laser UFO Skin and Fire God skins received a retexture.
* The turret is a reference to the "Engineer" from Team Fortress 2, who is also able to construct a Sentry Gun.
* The skin of the wrecked turret in the Living Room changes depending on the skin assigned to Engineer the last game.
	+ This does not apply to the NPC Engineer in the dungeon.
* Turrets spawned by Engineer always face to the right if there are no targets present, regardless of the way Engineer is facing. This is true for both the gun turret and laser turret.
* The Engineer is one of few characters whose head does not bob to music.
	+ It could be inferred that his "head" (the container resembling that of the Water Dispenser) is just a helmet similar to those of astronauts, and that his actual head is the water inside.
* The quote *"You see my brother in the dungeon?"* is a reference to the Water Dispenser.
	+ In the playerbase, the Engineer is often teased for this, as his head resembles the container of the Water Dispenser.
	+ Engineer's starter weapon is also called H2O.
	+ Engineer also appears as the icon for the Firefighter achievement.
