Modern Warfare 4 DMZ opens October 20

Early access does not guarantee PvE-only lobbies: turning off squad fill lets players enter solo, but other players may still be present.

Call of Duty: Modern Warfare 4’s DMZ mode would open to eligible pre-order players on October 20, 2026, three days before the game’s full launch. Eurogamer.net and IGN report that the early window applies to the new game’s extraction mode.

The campaign unlocks earlier, on October 16. The outlets list early access to both the campaign and DMZ for PC, Nintendo Switch 2, PlayStation 5, and Xbox Series X/S.

DMZ has its own separate progression. Infinity Ward calls this version the series’ “definitive extraction shooter experience” and describes persistent progression in the open-world Hajin Exclusion Zone.

Early access does not come with a promise of a PvE-only lobby. Players can turn off squad fill to go in solo, but Infinity Ward says that will not guarantee a lobby without other players. Going alone means opting out of a squad, not opting out of everyone else.
