Activision has taken the PC version of Call of Duty: WWII offline shortly after its release on Game Pass due to reports of hacking incidents, specifically Remote Code Execution (RCE) attacks that compromised players' PCs. The decision follows a history of cheating issues in the Call of Duty franchise, particularly in multiplayer modes. Activision announced the game's removal on Twitter on July 4, 2025, while investigations are ongoing, but no timeline for its return has been provided. Meanwhile, other Call of Duty titles like Black Ops 6 and Warzone continue to operate, and Call of Duty: Black Ops 7 is set to launch later this year.
