Modern Warfare 4 DMZ adds 70 levels, four AI tiers and a persistent base

Modern Warfare 4 DMZ launches on October 23 across five platforms

Infinity Ward has outlined DMZ for Call of Duty: Modern Warfare 4 in details published on October 6, presenting it as a combat-focused extraction mode rather than a looting and menu-heavy experience. The mode launches with Modern Warfare 4 on October 23 for PC, PS5, Xbox Series X/S and Switch 2.

DMZ builds on the beta from Modern Warfare 2 but gives the mode its own progression and economy. You can earn 70 dedicated levels only by playing DMZ, while cash and crafting materials remain in your DMZ inventory between runs. Weapon progression is shared with Modern Warfare 4 multiplayer and Warzone, creating one link between the extraction mode and the rest of the game.

Haijin uses four enemy tiers and Infinity Ward's largest AI population

The Haijin map contains what Infinity Ward describes as its largest enemy AI population to date. Its forces are split across four aggression and power tiers, with Commanders at the top. These roaming threats travel with groups of powerful guards, so reaching a Commander requires dealing with the escort first.

Missions and side operations provide XP while sending players across Haijin to fight AI enemies and other players. A new deployment screen lets you choose a mission type before entering a match, although you can still deploy without an objective and discover missions during the run.

The Forward Operating Base stores DMZ's long-term systems

Every player receives a Forward Operating Base, or FOB, that functions as a persistent space for post-run preparation. From the FOB, you can manage operators, inspect your stash, build loadouts, customise weapons, use a firing range and accept missions called Orders.

The base also includes a 3D printer that turns field-collected ingredients into useful items. Other stations and displays cover item purchases, dog-tag collections, PvP rankings and intelligence on powerful AI bosses. A vendor sells weapons and equipment for in-game cash, while the bounty leaderboard records leading PvP players.

DMZ separates its identity while sharing weapon progress

DMZ's 70-level track, retained resources and FOB give it a self-contained loop, but shared weapon progression connects each extraction to multiplayer and Warzone. For players choosing where to spend launch-night sessions, that means DMZ offers its own long-term systems without completely isolating weapon development from Modern Warfare 4's other modes.
