Call of Duty: Modern Warfare 4's campaign opened to early access on October 16, 2026, according to gamingbible, which reported the full retail release remains set for October 23, 2026. PC Guide reported that the early-access window began at 10 a.m. PDT on October 16, with local start times ranging across time zones up to 6 a.m. NZDT on October 17 in New Zealand.
Who can play early and how
Access to the campaign ahead of launch is tied to pre-orders. Gamerant reported that the only way to unlock early campaign access is to digitally pre-order either the Standard or Vault Edition of Modern Warfare 4; physical retail copies from stores such as Amazon or GameStop do not qualify, since discs ship only on the official release date.
According to gamerant, the eligible digital platforms are PC (Steam and Battle.net), PlayStation, Xbox and Nintendo Switch. Gamingbible separately listed PC storefronts including Steam, Battle.net and Xbox on PC, alongside PlayStation 5, Xbox Series X/S and Nintendo Switch 2, as supported platforms for the pre-order benefit.
Gamingbible reported that PC preloading opened a day earlier, on October 15, 2026, and that the game requires at least 115GB of available SSD storage at launch, with additional space potentially needed for day-one updates. The outlet noted that official preload timing and storage requirements for consoles had not been confirmed by Activision at the time of its report.
What is included in early access
The early-access period covers the single-player campaign only. Gamerant reported that multiplayer and the game's extraction mode, DMZ, are not part of the early window and are intended to launch alongside the rest of the game to keep an even playing field for all players.
Gamingbible's reporting, however, described a separate early-access date for DMZ, saying the mode would become available to digital pre-order customers on October 20, 2026, ahead of the October 23 full launch. The two outlets' accounts of DMZ timing differ, and NIVΞCTOR is reporting each as stated by its source.
Early reviews of the campaign
A review published by 247videogame.com described the campaign as delivering tactical mission design with player agency, environmental variety and visual polish, alongside strong character writing. The review called the campaign's final act memorable and said it offers what it termed a satisfying coda, while also noting occasional pacing lags.
The same review said the campaign emphasizes themes of loyalty, consequence and sacrifice, mixing intimate character moments with larger set pieces, and praised its sound design and lighting. It stopped short of calling the campaign genre-redefining.
