Call of Duty fans, mark your calendars — the Modern Warfare 4 Open Beta is finally here, and it’s your first real shot at the guns, maps, and chaos before launch day. Whether you pre-ordered or you’re just beta-curious, here’s everything you need to jump in without missing a beat.
What’s Actually in the Beta?
MW4’s beta isn’t just a taste test — it’s a full appetizer platter. You get core 6v6 multiplayer across several maps, the frantic new Kill Block mode, and even a slice of the single-player campaign with the mission “Entrenched.” Weekend 2 turns things up further with Ground War: Combat Outpost and the all-new Zodiac Resurgence map in Warzone. Best part? Whatever you unlock carries straight into the full game on October 23.
