Black Ops (Half-Life)

Black Ops are a fictitious commando group briefly seen in the first-person shooter computer game Half-Life and later expanded upon and featured in its expansion pack Half-Life: Opposing Force. Working independently of the Hazardous Environment Combat Unit, the Black Ops invaded the Black Mesa Research Facility to conceal any evidence of the resonance cascade.

Half-Life
Black Ops first appear in Half-Life during the chapter Apprehension, and later make one more appearance during the chapter Lambda Core. Only female Black Ops, also known as female assassins, are seen in the game.

Female Black Ops are strikingly nimble and agile, able to sprint faster than any other enemy and can to jump to extreme heights. They wear a black, latex suit and use night vision goggles that includes a headset with microphone, although none are ever seen speaking. They are armed with a silenced GLOCK 17 and grenades. At close range, they use an array of kicks to fight the player. When playing under the hardest difficulty level, female Black Ops have a cloaking field which they use to become invisible during combat, only revealing themselves when moving.

Female Black Ops were originally intended to be armed with crossbows as a weapon. The quivers they used to hold their arrows can still be seen on their belt in the final game.

The distinction between the Hazardous Environment Combat Unit and the Black Ops was not made at first in the original Half-Life. Although the two groups never encountered one another in the game, female assassins were coded to fight on the same side as the marines. Many players assumed this meant they were working with the military since assassins had no backstory, and as such, many fan-made maps included them fighting alongside each other. It was not until the release of Opposing Force that more insight regarding the Black Ops was revealed.

Half-Life: Opposing Force
Gearbox's expansion pack Opposing Force explained the Black Ops' purpose for occupying Black Mesa. The game tells that, after the initial failure of the HECU's clean-up operation, the Black Ops were sent to cover up the whole incident by destroying the entire facility. To do this, they intended to set off a thermonuclear device within the complex. Adrian Shephard locates the bomb the Black Ops delivered in a parking garage and is able to disarm it, but shortly after is seen being reactivated again by the G-Man. The nuke is later witnessed detonating successfully.

During gameplay, Black Ops are shown to have a great contempt for the HECU marines, considering them incompetent and inept. One soldier angrily remarks to another, "Why do we always have to clean up a mess the grunts can't handle?" Black Ops act hostile towards marines, killing any that have not yet escaped as part of their mission. Opposing Force introduced the group's male variant. Male Black Ops, also known as male assassins, wear black combat gear and full face masks that only expose their eyes. Some are seen wearing night vision goggles. Although not visible, they apparently have a communicator in their ear which they are seen listening to whenever they eliminate a target.

They are equipped with the same MP5N (M4A1 Carbine with the High Definition Pack) with grenade attachment that the marines use, but male Black Ops have a M40A1 sniper rifle instead of a shotgun. Black Ops utilize equipment and vehicles, such as trucks and Apaches, similar to the HECU, but black in color.

Black Ops soldiers can run much faster than the marines, and up close, they use martial arts kicks and punches as melee attacks. Also, unlike their marine counterparts, Black Ops operate in total silence when in combat, not even yelling in pain when injured.
