MW4's DMZ Opens Early for Preorder Players on October 20

Activision has confirmed that DMZ, the extraction-based mode in Call of Duty: Modern Warfare 4, will be playable for early access starting Tuesday, October 20. That is three days ahead of the game's full release. Campaign early access begins a few days earlier, on October 16, so preorder customers get roughly a week with the single-player story before everyone else.

The early window is tied to preordering. Any edition qualifies, including the standard and Vault versions, and the perk applies on PS5, Xbox Series X|S, Switch 2, and PC. Players who haven't preordered will have to wait for the general launch to get into DMZ.

If you haven't followed the mode, DMZ is an open-world experience that mixes human players with AI combatants. Squads search the map for loot, craft gear, and complete objectives. As with other extraction games, the goal is to reach an exfil point with your rewards intact. Lose the fight before then and the haul goes with you.

DMZ first appeared in 2022 alongside Modern Warfare 2 and was tied to Warzone as a free-to-play beta. That version was rough, and many players never warmed to it. The MW4 version looks like a much more serious attempt, and it adds a social space where players can gather between runs. We will need hands-on time to judge whether it lives up to the early impressions, but the extra runway before launch gives players a chance to find out for themselves.
