"Treyarch Shifts Focus to Call of Duty Black Ops Gulf War, Leaving Modern Warfare Zombies Behind"

Treyarch has confirmed that it has moved on from developing Modern Warfare Zombies, with Sledgehammer Games taking over the remaining story and content. The shift in focus is likely in preparation for the upcoming Call of Duty game, Black Ops Gulf War, which is expected to launch with its own Zombies mode. This move follows a lack of content updates for Modern Warfare Zombies, leading fans to declare the mode "dead" just three months after the release of Modern Warfare 3.
