Return of Zombie Ops is a zombie modification for Call of Duty 4, it features content from Black Ops Zombie mode aswell as from Modern Warfare 3 Survival mode and Ghosts Extinction mode. It's set slightly in the future with some weapons from Ghosts, Black Ops series and Modern Warfare series.
The tactic knife caused to many problems (infinite melee range, lol) so I replaced it with the ballistic knife :D
WHEN IS THIS COMING OUT??!!!!!
Prepare yourself for a double stab!
