Modern Warfare 4 Beta Schedule

The beta rollout is split into two distinct windows. The early access period runs from August 21 to 25, 2026. Following that, the open beta runs from August 28 to September 1, 2026. Players waiting for the open beta weekend do not require a code, as access opens to all players automatically across all supported platforms.

What is Included in the Early Access Beta

Activision confirmed that the early access build features five new 6v6 maps—including Rooftops, Silkworm, Transit 213, Cachette, Lotus, and Kill Block—alongside multiplayer modes like Team Deathmark, Domination, Hardpoint, Kill Confirmed, Inflation, Search & Destroy, 10v10 & 3v3 Gunfight, and the Mobility Course. Notably, this beta period marks the first time a campaign mission—specifically an entrenched mission—will be playable during a Call of Duty beta.
