Image via Activision Category: Get ready to deploy into Zodiac. | Published: Aug 28, 2026 03:04 am Call of Duty: Warzone is getting its first taste of Modern Warfare 4 as the MW4 Open Beta introduces the new Resurgence map Zodiac, revamped movement, weapon tuning, and several new gameplay features. The first-ever Warzone mode in a beta goes live on Aug. 28 at 10am PT and runs until Sept. 1, giving players an early look at what to expect when Modern Warfare 4‘s Warzone integration arrives later this year. MW4 Open Beta introduces Zodiac in Warzone Resurgence, a new map developed by teams behind Rebirth Island and Vondel. Set in South Korea and centered around a massive weapons manufacturing facility, the map features 10 POIs with dynamic environmental elements such as moving solar panels and twin trains at the center. Movement in the Warzone Beta will closely follow MW4 Multiplayer for a more grounded and deliberate feel while maintaining the momentum players expect from Resurgence. That means there’s no omnimovement, but you can expect to have tactical sprint. No omnimovement here. Image via Activision Weapons are also being tuned specifically for Warzone. Infinity Ward has adjusted damage ranges, bullet velocity, ADS speed, sprint-to-fire speed, and mobility, while keeping TTK familiar for players coming from the current Warzone experience. Custom loadouts won’t be available in the beta. Instead, players will use hand-crafted default loadouts and ground loot weapons featuring Modern Warfare 4 guns and equipment. Infinity Ward is also adding new gameplay elements, including Fuel Barrels and the SAM Turret field upgrade. Players can use Fuel Barrels as environmental interactions while you can deploy SAM Turret to defend against aerial killstreaks like UAVs and Counter-UAVs. Killstreaks will feature a broader selection from Modern Warfare 4 Multiplayer, although the strongest options will remain rare. Recon Contracts now reward a single-use Insight Killstreak, allowing players to activate circle peek when they need to know zone of the upcoming gas circle. Supply Run Contracts have also been changed to provide a one-time discount and upgrade buy stations with exclusive items. Warzone Beta launches with Resurgence Quads, while Casual Resurgence Quads will rotate in during the testing period. Both playlists will temporarily be disabled in the live game to encourage Resurgence players to try the beta and provide feedback. Open Beta Multiplayer details to follow. Image via Activision Infinity Ward has separately confirmed aim assist changes for the MW4 Open Beta following feedback from the Early Access weekend. The developer, however, remains silent on player demands for changes to SBMM. You can check out the complete details in the official MW4 Beta patch notes page. The Modern Warfare 4 Open Beta is available to everyone from Aug. 28 to Sept. 1 on PS5, Xbox Series X|S, PC via Steam, Battle.net, and Xbox on PC, as well as Nintendo Switch 2, regardless of pre-order status.
