Call of Duty Modern Warfare 4 will open its early access on August 21, 2026, granting pre‑ordered PC, Xbox, and PlayStation 5 players an exclusive preview of the next‑generation multiplayer experience.
Beta Timeline
Early access runs from August 21 through August 25, 2026, and is limited to owners who pre‑ordered the title on PC, Xbox Series X/S, or PlayStation 5. Once that window closes, an open beta launches on August 28 and ends on September 1, 2026, allowing any player to join without purchasing the game.
What the Betas Offer
Both phases give access to a broad array of multiplayer maps and modes, including the new extraction‑style DMZ setup. Operators are fully available, complete with all Vault Edition options for those who locked in the premium pack. Players can unlock up to nineteen weapons, ranging from small‑scale 3 v 3 skirmishes to large‑scale battles featuring tank units.
Limited Features and Future Surprises
The campaign remains locked during both the early access and open beta periods, a practice that mirrors earlier Call of Duty releases. Activision has teased additional Beta rewards and surprises that will be unveiled in the coming weeks. A dynamic weather system will accompany the DMZ mode at launch, promising to impact gameplay flow. The open beta is also open on Nintendo Switch 2, expanding the supported roster to that console.
