Modern Warfare 4 Campaign Early Access Is Live, With DMZ Access Set for Oct. 20

Call of Duty: Modern Warfare 4 Campaign Early Access is now live, opening the 16-mission story to players who digitally pre-ordered or pre-purchased the Standard Digital Edition or Vault Edition. Access is available on Xbox Series X|S, Xbox on PC, PlayStation 5, Battle.net, Steam, and Nintendo Switch 2, and remains open through the October 23 launch. Activision’s official access details list the eligible editions and platforms.

The story follows Private Park Hyun Jun and his squad as they fight a full-scale invasion across the Korean Peninsula. John Price, now an outlaw, is also hunting the person behind the conflict.

Campaign rewards arrive in Multiplayer and DMZ at launch

DMZ Early Access opens globally on Oct. 20

DMZ Early Access begins at 10:00 AM PT on Tuesday, Oct. 20. The unlock is simultaneous worldwide, so the local time varies and some players will see the date roll over to Oct. 21. A Standard Edition preorder is enough to qualify, with no higher-tier edition required.

Multiplayer is scheduled to open with the full game on October 23. DMZ also has its own progression loop, with successful deployments feeding FOB upgrades between runs.

The full game is scheduled to launch at midnight local time on October 23, rather than at one worldwide hour. PC preload is available now, and the Steam page lists 115 GB of storage and the system requirements.

Does the global DMZ unlock land at a useful hour where you are? For the move from Campaign Early Access into DMZ’s October 20 opening, stay connected on X, Bluesky, YouTube, Instagram, Steam, and Telegram.
