War erupts on the Korean Peninsula as North Korea launches a full-scale invasion that threatens to destabilize the world in Call of Duty: Modern Warfare 4. A young squad of South Korean soldiers fights to survive on the collapsing front lines, while half a world away a vengeful Captain Price wages a personal war from the shadows as he stays one step ahead of those hunting him. As Price’s off-book mission collides with the forces behind the invasion, the war spreads beyond anyone’s control.
