Call of Duty: DMZ

DMZ was the extraction mode that launched inside Call of Duty: Warzone 2.0 on November 16, 2022, alongside Call of Duty: Modern Warfare II.

Squads of up to three deployed into Al Mazrah, the large map shared with Warzone 2.0 (with Ashika Island, Vondel, and the keycard-gated Building 21 instance added later), to run faction contracts for groups such as Legion, Black Mous, and White Lotus, pull loot and keys from locked caches, and reach an exfil chopper before the map's AI and rival squads caught them. Two things set it apart: the stakes and the diplomacy. Gear and insured-weapon slots carried between deployments, so what you brought in could be lost for good, and squads could assimilate strangers into a team of up to six mid-raid, turning a firefight into an uneasy truce. Those unscripted standoffs are what its players remember. Activision ran DMZ as a Beta for its entire life; it never moved to a 1.0 release.

DMZ is Call of Duty history more than a title you would install fresh today, and where it is still reachable it runs on the Modern Warfare II client with the same RICOCHETAnti-cheatActivision RICOCHETRICOCHET is Activision's in-house kernel-mode anti-cheat, deployed across the Call of Duty franchise since 2021.

The successor is no longer a rumor: DMZ returns inside Call of Duty: Modern Warfare 4, releasing October 23, 2026, and it has its own plate in this guide. When it ships, the question worth asking is the one this guide always asks: what loads, when, and on whose say-so.

DMZ ran on the Modern Warfare II / Warzone 2.0 client, so it carried the same trust ask as the rest of that release. RICOCHET, Activision's kernel-mode anti-cheat, loaded with the game and unloaded when it closed. There was no separate DMZ install and no separate anti-cheat layer; the main Windows process was cod.exeProcesscod.exeCall of Duty HQ launcher (shared front-end)Open plate →, shared with Modern Warfare II and Warzone 2.0, and the broader picture lives under the ricochet anti-cheat family entry. Because DMZ shared the base game's client, its trust posture and Modern Warfare II's are the same one.

DMZ's arc is unusually well documented because it ended in the open. In December 2023, with Modern Warfare III's first season, Activision confirmed DMZ would get no further content updates and would be separated from the Modern Warfare III and Warzone ecosystem, left reachable but frozen, with progression no longer carrying forward; GameSpot, Kotaku, Charlie Intel, and Dot Esports reported it. Across its run, players and reporters documented a cheating problem that the mode's stakes made especially cruel: because death meant losing your gear, cheaters used aimbots and, notably, server-crash exploits that booted everyone from a session so the cheater could grab loot or dodge a loss, which RICOCHET never fully contained. For a mode whose whole tension was that loss was real, cheating did not just take a match, it took the thing you carried in.
