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.
    • This does not apply to NPCs as they still target the assassins normally.
  • When moving, the cloaking device will not function until the assassin stops.
