The Hazardous Environment Combat Unit Engineer, commonly abbreviated as the HECU Engineer, is an HECU class introduced in Half-Life: Uplink and formally introduced as an ally in Half-Life: Opposing Force.
The Engineer is equipped with the tools necessary to adapt to changing situations in the field, mostly by cutting through sealed doors or floor grates with his welding torch. To have him using his torch, he has to be led to the target door, although he sometimes starts working without being ordered when close enough to the door. He wears special goggles to protect his eyes from the welding torch's light.
Like a regular soldier, the Engineer is also capable of fighting with his Desert Eagle.
Keeping an Engineer alive is very important when only one is available to clear the path, as the mission may fail if the Engineer is killed before he can open inaccessible entrances.
One should also be careful not to allow the torch fuel tank to sustain damage. If the canister is pierced, it is likely to explode. When this happens, the Engineer is killed and the explosion causes immense damage. This rule still applies after The Engineer is killed; through it may be useful for killing enemies who're near it. (Caution must be taken that no other allies be in the sight of a dead Engineer or they will shoot the player once they see the player detonated the canister)
Engineers have been known to light torches using their cigarette.
The Engineer only directly appears in Opposing Force, where he is first introduced in the training chapter, Boot Camp, during the "Squad Training" exercise. In the other games, his presence is only suggested when a door is cut, the Marines standing behind being only generic models.
Engineers have been seen fighting Xen creatures, Race X creatures, and Black Ops.
