Activision Cancels Standalone Call of Duty: Zombies Game

The proposed live-service game, envisioned as a standalone project by Raven Software, was halted due to strategic decisions by Activision.

Former developer Michael Gummelt revealed details about the canceled Call of Duty: Zombies game, which was planned to be a live-service, standalone project.
The game, conceptualized between 2011 and 2012, was intended to feature a four-player co-op mode in a post-apocalyptic setting.
Despite never progressing beyond design documents, the game was to include microtransactions and seasonal updates, drawing on concepts from Call of Duty Online.
Activision ultimately decided to cancel the project, preferring to retain the Zombies mode within the main Call of Duty games under Treyarch's development.
Fan reactions to the revelation of the canceled project have been mixed, with some agreeing with Activision's decision to cancel the standalone game.
