Here is what the page “Call of Duty: Modern Warfare 4 DMZ Early Access: How to Play 3 Days Early” contains. Activision has confirmed that Call of Duty: Modern Warfare 4's DMZ mode will be playable early for preorder customers starting October 20, three days before the game's official launch. The campaign early access begins even earlier on October 16. To get in, you need to preorder any edition of MW4, including standard or Vault, on PS5, Xbox Series X|S, Switch 2, or PC.
DMZ is described as the "definitive extraction shooter experience," an open-world mode with human players and AI where you loot, craft, and complete objectives before reaching an exfil point. This version is a major upgrade from the mode's debut in 2022's MW3, and it introduces a new social space. Early access gives dedicated players a head start on mastering the new map and mechanics before the full player base arrives.
