Call of Duty: Modern Warfare 4 received an update on October 29, 2026, which introduces a new Halloween-themed playlist mode called Possession.

The update resolves multiple technical flaws, interface troubles, and errors. Fixes include improvements to weapon and challenge systems, player progression, and several DMZ mechanics such as hostage interactions, extraction, and Scavenger detection.

Modern Warfare 4 launched on October 22, 2026, for PC, PlayStation 5, Xbox Series X|S, and Nintendo Switch 2. On the Switch 2, the campaign and DMZ modes target 30FPS, while multiplayer targets 60FPS, though performance may dip during gunfights. Players noted that the Switch 2 version has muddier textures than a PS4 version and that HDR can make dark levels difficult to see. Disabling cross-play on the Switch 2 can result in lobby wait times of five to ten minutes. The game's size was reported as 132GB at initial download, but settled at 87.4GB after play.
