MW4 DMZ is an extraction mode for Call of Duty: Modern Warfare 4, building upon the PvPvE formula.
Complete faction missions, loot valuable gear, and fend off both AI combatants and rival operators.
Reach extraction zones and board a helicopter before time runs out or the radiation zone consumes the map.
It’s an evolved experience featuring deeper progression systems, dynamic environments, and higher-stakes.
