Duty calls.
With Call of Duty: Modern Warfare 4 previously confirmed for the Nintendo Switch 2 and slated to release on October 23, 2026, it has now been confirmed that the game will receive two Open Beta Tests in August.
The first Open Beta is set to begin on August 21, 2026, for those who pre-ordered the game on PlayStation 5, Xbox Series X|S, and PC. The second will follow a week later on August 28, 2026, for Nintendo Switch 2 players.
When speaking about what to expect during the Open Beta Tests, Activision shared the following:
Get ready to drop into multiple Multiplayer maps and modes, choosing from a wide selection of brand-new Operators, including all the Vault Edition Operators for players who pre-order the Vault Edition, and unlocking as many as 19 different weapons before deploying into everything from small-scale 3v3 skirmishes to massive tactical battles featuring tanks and more. Test your mettle across new and returning modes, from Search & Destroy to the brand-new Kill Block, plus the Training Mobility Course.
Three operators advance through a burning building, led by a heavily armored Operator carrying a rifle.Experience fluid movement and best-in-class ballistics, building your own loadouts with the optional help of Gunny, leveling up as you unlock a wide variety of weapons, Tacticals, Lethals, Field Upgrades, Perks, and Killstreaks.
And that’s just scratching the surface… expect more gameplay intel soon!
Furthermore, pre-orders for the Nintendo Switch 2 version will begin on 26 August 2026. Five days earlier, on 21 August, Call of Duty: Next is set to take place, featuring live gameplay, an in-depth briefing on the Multiplayer content coming to Modern Warfare 4, developer insights, and new reveals ahead of the Beta.
Lastly, more details have been shared regarding the new Kill Block multiplayer mode. Catch the new trailer and overview here:
Kill Block was the center of gravity. Set within the West Bridge Advanced Military Training Facility, the new Multiplayer experience made its public debut with fast, aggressive 10v10 Gunfight matches, giving players a first taste of Modern Warfare 4’s adaptive live-fire training environment. Designed for fast-paced, close-quarters combat, Kill Block’s ever-changing battleground rewarded repeat play, encouraging players to rethink their tactics from one match to the next, and drew crowds throughout the weekend.
About Call of Duty: Modern Warfare 4:
This next installment pushes the action into darker and more dangerous missions, where consequence and escalation bring long-running storylines to a powerful and emotional breaking point. In Campaign, players will drop into a variety of engagements — from trench warfare in Korea to high-octane chases through Paris and close-quarters combat in New York. Multiplayer1 will deliver grounded, precise combat where fluid movement, player choice and greater control define every engagement. In DMZ, every extraction run into contested territory forces hard choices about which objectives to pursue, what to secure, and when to get out.
