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.
Just wanted to show some kind of progress again...
Weapons on the back now remain with their camo.
Two Primary Guns will only be possible with the right gear or in Classic gamemode.
