The Kassimir Mechanism is a device at the center of an Easter Egg in the Call of Duty: Black Ops Nazi Zombies map Ascension. It is found by completing several objectives to divert power to the mechanism. Its existence is proven by the Space Program Announcer that speaks of it needing repairs at the beginning of a zombie round in Ascension. The Easter Egg starts at the start of the game with Gersch pleading for help and saying that she (Samantha Maxis) is coming and the mechanism must be repaired.
