PowerInvisibility is an internal class. An item of this class is placed in the player's inventory while he is having Doom's partial invisibility. With this effect on the player is drawn in the fuzzy render style, like the Spectre and the aiming of monsters is randomly off. Additionally, any monster that hasn't been alerted yet will have difficulty seeing the player.

Like all other Powerups items of this class are never used directly. Instead you have to create a new item that inherits from PowerupGiver to give it to the player.
