About Call of Duty: Modern Warfare 4
Developed by Infinity Ward, with Beenox on the PC version, and published by Activision, Call of Duty: Modern Warfare 4 releases on October 23, 2026 for PC, PlayStation 5, Xbox Series X|S, and Nintendo Switch 2. It's the 23rd Call of Duty game and the fourth Modern Warfare entry, built natively for current-generation hardware, with no PS4 or Xbox One version. War erupts on the Korean Peninsula when North Korea launches a full-scale invasion. You play Private Park, a young South Korean soldier fighting on the collapsing front lines, while Captain Price, now an outlaw, wages a personal war from the shadows. The campaign runs from trench warfare in Korea to close-quarters combat in New York, high-octane chases through Paris, SAS night raids in Mumbai, and city-wide assaults to reclaim occupied territory.
Multiplayer is built around grounded, precise combat. The Ballistic Authority system ties aiming, recoil, bullet trajectory, weapon motion, sound, and visibility together, and there's no bloom, so firefights stay consistent. It launches with 12 new 6v6 maps, alongside Gunfight and large-scale Big War environments, a redesigned Create-a-Class system, deep Gunsmith customisation, and Kill Block, a dynamic battlefield that can change its layout between rounds. DMZ returns as an extraction mode where you operate behind enemy lines and decide which objectives to pursue and when to get out. Digital pre-orders unlocked the campaign on October 16, and DMZ early access starts on October 20.
The Xbox on PC version is an Xbox Play Anywhere title, so one key works on both your console and your PC.
