According to Activision, Call of Duty: Modern Warfare 4 releases on October 23, 2026, with an early access multiplayer beta starting August 21, 2026, across PC, PlayStation 5, and Xbox Series X/S. Players can secure beta entry by pre-ordering the game, purchasing a Discord Nitro subscription, or waiting for the open beta period beginning August 28, 2026.
Call of Duty: Modern Warfare 4 Beta Schedule
Activision has scheduled two separate testing windows ahead of the October launch. According to official release details, the initial Early Access Beta kicks off on August 21, 2026, at 2 p.m. ET / 11 a.m. ET / 10 a.m. PT on August 25, 2026. PC, PlayStation 5, and Xbox Series X/S users can preload this version starting August 20, 2026, at noon ET / 9 a.m. PT.
Following the first weekend, an Open Beta runs from August 28, 2026, at 1 p.m. ET / 10 a.m. ET / 10 a.m. PT. Insider Gaming notes that Nintendo Switch 2 players are locked out of the first weekend but can join the open beta pool during this second phase. Preloading for the open beta begins on August 26, 2026, at noon ET / 9 a.m.
Pro Tip: Digital preorders automatically grant access to platform stores without needing a redemption code, whereas physical purchases include an explicit token sent via email.
How to Secure Modern Warfare 4 Early Access Beta Codes
Securing a spot in the initial August testing window requires specific steps outlined by Activision. Players can gain entry through two primary methods:
- Game Preorder: Preordering digitally on PlayStation 5, Xbox Series X/S, Xbox on PC, Steam, or Battle.net hooks the account directly into the beta. Physical retail preorders include a printed code to redeem on the official Call of Duty website.
- Discord Nitro: Active subscribers paying $9.99 per month can claim a beta token through the Nitro Home under the Nitro Rewards section, as detailed in publisher guidelines. Users must then redeem that code directly on the Call of Duty portal.
As Insider Gaming points out, past franchise rollouts occasionally offered alternative entry routes like Twitch Drops, though players should monitor official channels for any additional reward announcements.
