The AH-64 Apache is a US military attack helicopter used by the HECU and the Black Ops during the Black Mesa Incident. It is armed with rockets and a 360 degree swiveling turret, making attempts to engage it without cover futile. Several Apaches were stationed at Black Mesa before the Resonance Cascade occurred, and more were brought in from nearby Santego Military Base, Arizona, after the event.
The Apache is first seen during the train ride in Half-Life's first chapter, Black Mesa Inbound, idling on a helipad. The player first encounters it in a combat situation in the chapter Surface Tension, in which one is providing close air support for some dug-in HECU troops guarding the Hydro-Electric Dam Freeman must cross. It pursues Freeman through desert areas until it is defeated with the RPG on a steep cliff preceding the Topside Motorpool.
The Apache is a tough and effective foe. It is armored against small arms fire, meaning that, although it is possible to take one down with bullets, destroying the Apache with anything less than explosives or experimental weaponry is difficult. The RPG is by far the most effective weapon against the Apache, but it (or sufficient ammunition for it) may not always be available. In these cases the Tau Cannon can destroy it with only a couple of hits with a charged shot (only one in Easy mode). If both are unavailable, shooting the main rotor works, though it takes a long time and wastes ammo and health.
- The Apache is primarily used by the US Army (the "Army" decal is also visible on the model). As the United States Marine Corps uses the AH-1 SuperCobra as their attack helicopter, this suggests joint involvement between multiple military branches for the same operation.
- In Half-Life: Source, the Apache is vulnerable anywhere on its body.
- The missile model seen in Half-Life does not represent the actual standard missile used by the AH-64 Apache, the AGM-114 Hellfire.
- The missile model seen in Half-Life: Source is similar to the RPG rocket model.
