Wiki conjecture
The title of this article is conjectural.
Although this article is based on official information, the actual name of this subject is pure conjecture.

The cloaking device is a technology used by the female Black Ops in Half-Life and Half-Life: Opposing Force, in Hard mode only.


  • Giving them partial invisibility when shooting at the player or throwing grenades, the cloaking device makes the Black Ops difficult to see and defeat in combat.
  • The cloaking device works only when an assassin remains still and/or uses a weapon; it deactivates itself whenever they are moving.
  • The cloaking device does not affect other NPCs and they can still clearly see the assassin.
