Call of Duty: Modern Warfare 4 Is Here — Infinity Ward Brings Back the Original Team on Day One

Today, October 23, 2026, Activision drops Call of Duty: Modern Warfare 4 — the most anticipated FPS of the year. Developed by Infinity Ward, the studio behind the original Modern Warfare trilogy, this is a full-circle moment for a franchise that spent several years under different developers. It's available now on PlayStation 5, Xbox Series X|S, PC, and Nintendo Switch 2.

Campaign Early Access Already Ran

Infinity Ward gave pre-order buyers a head start: Campaign Early Access opened October 16, a full week ahead of launch. That's a generous window that let the internet chew through the story before multiplayer doors opened. Expect spoilers if you haven't played it yet.

What's in the Multiplayer Box

The launch lineup ships with 12 Core 6v6 maps, spanning varied environments across different time zones and combat scenarios. Shipment — one of the most iconic small maps in franchise history — arrives a few days later on October 27, likely to avoid server chaos on day one. Season 1 and Warzone integration are incoming shortly after launch, bringing cross-progression and seasonal content to the wider Call of Duty ecosystem.

No Game Pass at Launch

Microsoft owns Activision, which makes this sting a little: Modern Warfare 4 is not available on Game Pass at launch. The Xbox store page confirms it outright. Microsoft may add it later, but for day-one players on Xbox, it's full price.

The Switch 2 Version

The Switch 2 version is listed alongside the other platforms, which is notable. Running a modern Call of Duty title on portable hardware at reasonable fidelity would be a meaningful technical achievement. Activision hasn't published detailed performance specs for the Switch 2 version yet, so portable players will want to check early reviews before buying.

What to Expect from Season 1

Warzone will integrate Modern Warfare 4 content and seasonal progression — the model the franchise has used since Warzone became the connective tissue between titles. Season 1 typically kicks off within weeks of a mainline launch and brings new operators, weapons, and limited-time modes. The competitive scene will be watching how the new maps play in ranked playlists once matchmaking settles.

Modern Warfare 4 is out now on PlayStation 5, Xbox Series X|S, PC, and Nintendo Switch 2.
