How the launch works
Modern Warfare 4’s launch rolls out in two stages. First, Campaign Early Access opens on 16 October 2026, letting players start the single-player story a week ahead of everyone else. Then the full launch arrives on 23 October, opening up multiplayer and the rest of the game for all platforms at once. MW4 releases across PS5, Xbox Series X|S, PC via Battle.net and Steam, and — notably — Switch 2, marking the series’ arrival on Nintendo’s new console. As ever with Call of Duty, post-launch seasons keep adding content: Season 1 lands on 6 November 2026 with the first Battle Pass, new maps (Hajin and Zodiac) and MW4’s integration into Warzone, following a short preseason run of returning modes.
