We’re getting Hajin, a new Warzone battle royale map for Call of Duty: Modern Warfare 4, rolling out with Season 1.

Hajin is described as one of the most ambitious COD environments yet, offering vast exploration, a large map scale, and a fresh, substantial experience for Warzone players in MW4 Season 1.

The map debuts ahead of Season 1 and will be playable in both Battle Royale and DMZ Evacuation modes on a Korean Peninsula setting.

Radiation-based environmental effects could influence gameplay in Warzone, with DMZ details hinting at potential cross-mode impact.

Key points of interest include the Irradiated Fallout Reactor, the Fortified Prison Complex, Hajin City Ruins, and the Abandoned Military Base, each offering distinct combat experiences.

The design blends open areas with cramped urban spaces to create varied pacing and firefight dynamics across Hajin.

Pre-release information comes from leaks and trailers, with full details to be confirmed at official launch; pre-order and beta access are being promoted to experience Hajin early.

In DMZ mode, teams infiltrate, loot, and extract, while Radiation features may affect both DMZ and BR play, introducing a different rule set per mode.

Practical steps for players include obtaining Warzone codes, and readers are invited to ask questions in the comments for more details.

In DMZ, Hajin is used for loot and extraction, whereas Warzone will host a traditional Battle Royale battle; differences between modes are to be clarified as rollout progresses.

Developers plan to separate Warzone’s BR experience from DMZ while using the same map, potentially refreshing BR dynamics if radiation anomalies persist across modes.

Hajin is described as a sprawling, radiation-scarred exclusion zone on the Korean Peninsula, featuring the Fallout reactor, a fortified prison, Hajin City ruins, and a military base, and is noted as the largest Warzone map to date.
