The real countdown begins

Beyond its October 23 release date, Modern Warfare 4's rollout has taken shape around early access, a beta, and a landmark platform debut. Infinity Ward's 2026 entry offers campaign early access beginning October 16, a full week before launch, for Standard Digital and Vault Edition buyers. It is the kind of pre-launch structure that has become standard for the franchise's biggest releases.

The most historically significant detail, though, is where the game is heading: onto Nintendo hardware for the first time at launch.

The rollout details

The confirmed pre-launch and platform picture:

Campaign early access begins October 16, 2026, ahead of the October 23 full release.
Platforms include PS5, Xbox Series X/S, Xbox on PC, Battle.net, Steam, and notably Nintendo Switch 2, a first for a mainline Call of Duty at launch.
The campaign casts players as Private Park, a South Korean soldier, alongside a now-outlaw Captain Price, and the DMZ extraction mode officially returns.
Pre-orders carry Vault Edition content plus a loyalty discount, with physical buyers redeeming a 13-digit beta code.

An open beta was expected in the late-August to mid-September window, structured as an early-access weekend followed by a public one, though that timing is an estimate rather than an Activision-confirmed date.

Why it matters

The Switch 2 launch is the headline. A mainline Call of Duty arriving day and date on Nintendo hardware is a genuine milestone, extending the franchise to an audience it has largely bypassed for years and capitalizing on the Switch 2's strong debut. For Nintendo owners who have watched Call of Duty from the sidelines, it is a significant addition to the platform's library.

The campaign early access reflects a now-familiar model of rewarding certain editions with a head start, letting eager players jump into the story a week before everyone else. Pairing that with a returning DMZ extraction mode, a fan-requested feature, gives the pre-launch period real appeal for the community.

The beta, redeemable via codes in physical copies and expected before launch, is the traditional proving ground where players test multiplayer and Infinity Ward gathers feedback. Its exact dates and any special beta content, including a reported experimental map, remained unconfirmed and should be treated as such until Activision posts specifics.

Taken together, the rollout positions Modern Warfare 4 as a major fall release with a broad platform reach and the usual layered launch. The Switch 2 debut alone ensures it will be one of 2026's most closely watched Call of Duty launches.
