Activision announced that it will provide hours of maintenance for ten Call of Duty series games today, during which game services will be interrupted, but no specific reasons are disclosed.The game lineup involved in this maintenance is huge, even including Modern Warfare 2, which was launched in 2009.The official emphasized that the maintenance window will last for four hours, and the games listed during this period will not be able to run.

There are many different opinions about this in the player community: some people think it is related to the upgrade of the anti-cheating system, while others speculate that it is preparing for a large-scale addition to the Xbox Game Pass subscription service, which recently included Call of Duty: World War II.
