Game information


The cloaking field[1] is a device used by the female Black Ops assassins in Half-Life and Half-Life: Opposing Force. It is only present on Hard difficulty.


If playing on Hard difficulty, female Black Ops will possess a cloaking field which grants them near total invisibility. While in an idle state and unaware of any threats, they appear fully opaque. Upon acquiring a target, their form will begin to fade out once they attack, making them difficult to see and defeat in combat. The cloaking field only works when an assassin remains still and/or uses a weapon; it deactivates itself whenever they are moving.
