Infinity Ward describes the upcoming DMZ mode in Call of Duty: Modern Warfare 4 as an "action extraction shooter," with the goal of encouraging more frequent player engagements. The mode will feature four tiers of AI enemies, along with high-value targets such as Commanders and Lieutenants.
Infinity Ward recently introduced this gameplay direction. Joe Cecot, Creative Director of Multiplayer, stated that players won't just be scavenging for supplies and occasionally running into an AI enemy or another player; the team aims to make engagements occur more frequently.
Defeating high-value targets such as Commanders and Lieutenants yields valuable loot. The presence of other players, gear, and supplies on the map also affects how frequently players encounter combat.
