Hajin in Warzone: What Call of Duty: NEXT Confirmed—and What Remains Unverified

Hajin is one of the major settings connected to the Modern Warfare 4 beta, but the available evidence supports a narrower conclusion than the full list of claims surrounding the map. Activision’s published beta information confirms two Combat Outpost maps set within Hajin, while the beta’s Warzone component is Resurgence on Zodiac.

What the available sources confirm about Hajin

The clearest verifiable Hajin detail is its role in Modern Warfare 4’s Combat Outpost content. The official multiplayer overview names Imjin Farmlands and Wolves Stadium as purpose-built Combat Outpost maps set within Hajin. They are designed around different combat environments, including open terrain, tall structures, and indoor objectives.

Activision’s beta guide also lists Combat Outpost alongside the game’s multiplayer and Warzone Resurgence content. That gives players an early opportunity to experience Hajin as a multiplayer combat setting before the full game releases.

The supplied sources do not independently establish several additional claims in the original brief, including that Hajin is Warzone’s sixth and largest battle-royale map, that it is larger than Verdansk or Al Mazrah, that it previously hosted DMZ extraction gameplay, or that it will be the primary battle-royale map for Season 1. They also do not provide enough source-backed detail to confirm the map’s alleged radiation hazards, tri-border setting, or campaign role. Those details should therefore be treated as unverified here rather than presented as confirmed Activision facts.

Modern Warfare 4 beta dates and access

The beta is split across two weekends:

• Early Access: August 21 at 11:00 a.m. PT through August 25 at 10:00 a.m. PT.
• Open Beta: August 28 at 10:00 a.m. PT through September 1 at 10:00 a.m. PT.

Early Access requires a Modern Warfare 4 preorder or prepurchase on supported platforms. Activision lists Xbox Series X|S, Xbox on PC, PlayStation 5, Steam, and Battle.net for the early-access period.

The Open Beta does not require a preorder and is available across all listed platforms, including Nintendo Switch 2.

What is playable in the beta?

The official beta guide lists these multiplayer modes:

• Team Deathmatch
• Hijack
• Inflation
• Domination
• Hardpoint
• Kill Confirmed
• Search and Destroy

The test also includes Combat Outpost content on Imjin Farmlands and Wolves Stadium, as well as Call of Duty: Warzone Resurgence on the Zodiac map.

The provided material does not publish a definitive list of every mode or feature being held back for the full launch. It does establish that the beta is a selected preview of multiplayer, Combat Outpost, and Resurgence content—not a complete representation of the October release.

When does Modern Warfare 4 launch?

Call of Duty: Modern Warfare 4 launches worldwide on October 23, 2026, according to Activision’s support information. The available sources confirm that date, but they do not independently confirm the precise timing of a Hajin battle-royale launch in Season 1. That distinction matters: Hajin’s presence in the beta is documented, while its broader Warzone rollout remains unverified by the supplied citations.
