About this game
Call of Duty: Modern Warfare 4 is a first person shooter that continues the rebooted Modern Warfare storyline following Modern Warfare III (2023). The campaign unfolds during a full scale North Korean invasion of South Korea, seen from the eyes of Private Park, a young South Korean soldier on his first deployment, and Captain Price, who conducts an unsanctioned, personal mission that ultimately intersects with the forces behind the conflict. Players experience trench fighting in Korea, urban battles to liberate occupied cities, close quarters encounters, high speed pursuits, and covert SAS style raids across multiple global locations. Multiplayer focuses on grounded, precise combat with 6v6 core maps, large scale vehicle based battlefields, and a dynamic Kill Block system that alters map layouts between rounds. The DMZ extraction mode casts players as off the books operatives infiltrating contested zones, weighing objectives and loot against the risk of failing to escape, and the game releases only on current generation consoles and PC.
