Modern Warfare 4 October 21, 2026 Kai Mercer
Two days before launch, Modern Warfare 4 got a patch on October 21 aimed squarely at early access feedback.
What changed
- DMZ progression: fixes for players whose progress wasn't tracking properly.
- Enemy AI: DMZ combatants were toned down after many players said they were too aggressive and too accurate.
- Campaign: a fix for a specific mission bug that was stopping some players from moving forward.
Why it matters
Progress earned in early access carries into the full game, so progression bugs were the main worry. If your DMZ missions seemed stuck before, try them again after updating.
