Call of Duty: NEXT Kicks Off: How to Join the Massive Modern Warfare 4 Beta

The future of the Call of Duty franchise is finally here. Today, Activision is hosting its highly anticipated Call of Duty: NEXT event, a fully digital, global livestream dedicated to pulling back the curtain on Call of Duty: Modern Warfare 4. As the excitement reaches a fever pitch, the event serves as the official launchpad for the game’s extensive early-access period.

A New Era for the Franchise

The event, which begins at 12 p.m. ET/9 a.m. PT, will feature over 1,000 creators and professional players demonstrating the latest gameplay. Attendees can look forward to deep dives into the game’s multiplayer suite, the evolution of Call of Duty: Warzone, and a closer look at the innovative "Kill Block" map—a dynamic battlefield that changes its geometry in real-time during matches.

The broadcast will also detail the new "Zodiac" Warzone map and provide insights from the development team at Infinity Ward. Viewers who link their Activision and Twitch accounts can earn exclusive in-game rewards, including the Gas Ready Emblem, Rapple Repel Calling Card, and the Ghost Helmet Charm.

The Largest Beta in CoD History

Activision is pulling out all the stops for this year’s beta, which is being touted as the largest in the history of the franchise. In a significant departure from tradition, players will have the opportunity to experience a full campaign mission titled "Entrenched," which drops players into a high-stakes, large-scale assault on a nuclear power station.

Weekend One of the Early Access Beta (August 21–25) will feature:

• Five Core 6v6 maps and six game modes, including classics like Search and Destroy and the brand-new "Inflation" mode.
• Gunfight: Available in both 3v3 and a new 10v10 format on the shifting Kill Block map.
• Mobility Course: A dedicated space for players to master the title’s expanded movement systems.
