Call of Duty: Modern Warfare 4 Beta Schedule Confirmed!

Activision and Infinity Ward have officially finalized the testing roadmap for Call of Duty: Modern Warfare 4. Following months of speculation, the studio confirmed two distinct weekends of multiplayer testing, designed to gather player feedback ahead of the game's worldwide launch on October 23, 2026. The beta phase begins on August 21, 2026, immediately following the Call of Duty: NEXT global broadcast, which will provide a deep dive into gameplay, developer insights, and new feature reveals.

Beta Testing Schedule

The first weekend is exclusive to those who pre-order the game on PC, PlayStation 5, or Xbox Series X|S. Digital pre-orders made through the Microsoft Store, PlayStation Store, Steam, or Battle.net will automatically register players for access. Those who purchase physical copies or digital codes via participating retailers will receive a 13-character code to redeem on the official Call of Duty beta portal.

The second weekend expands the pool significantly, inviting all players to participate without a pre-order requirement. Notably, this weekend marks the return of the franchise to Nintendo hardware, as the Nintendo Switch 2 joins the lineup. While Switch 2 pre-orders open on August 26, 2026, participants will not need to secure a copy of the game to engage in the open beta, though an active Nintendo Switch Online subscription is required.

Gameplay Content and Features

Infinity Ward has promised a substantial amount of content for the testing phase. Players will have access to 19 different weapons, a variety of new Operators, and a range of game modes. The beta includes both small-scale 3v3 skirmishes and larger tactical battles involving tanks. Returning modes like Search & Destroy will be featured alongside the highly anticipated Kill Block mode.

Kill Block represents a significant departure from standard map design. Situated within the West Bridge Advanced Military Training Facility, the map utilizes a modular system where three massive structures, or Slabs, physically reconfigure between matches and rounds. Activision notes that this system supports over 500 potential layout combinations, forcing players to adapt their movement and strategies in real-time. For those attending the Fanatics Fest NYC 2026, an exclusive demo of this dynamic map is currently available at the Javits Center.

In addition to new combat modes, players will have access to the Training Mobility Course to practice new movement mechanics. The game also introduces the Gunny system, a loadout assistant designed to streamline customization for players who prefer automated setup suggestions. For those using the Vault Edition, additional content includes the Hostile Alliance and Special Forces Operator packs, providing access to characters such as Price, Valeria, Ghost, and Blix, along with signature weapon blueprints featuring specific cosmetic variants.
