War Mode is a gamemode in Call of Duty: WWII and Call of Duty: Modern Warfare III, and a scrapped gamemode from Call of Duty: Black Ops 4. During the mode, an attacking team must complete strategic objectives while the other team defends said objectives.

Call of Duty: Modern Warfare 3 has received criticism for lacking original content, being seen as a glorified DLC for its predecessor. Still, the War multiplayer mode stands out in the game, offering large-scale objective-based gameplay that deviates from the usual CoD experience.
