A first look at Losing Ground, described as one of the two big war missions from the Call of Duty: Modern Warfare 4 Campaign, has now been released, with the vignette following a Korean grunt squad as they push through the chaos on the ground. The reveal arrives alongside confirmation that anyone who pre-orders Call of Duty: Modern Warfare 4 on any platform will gain access to the single player Campaign a week early, from 16 October 2026.
