What changed in the latest MW4 beta patches?
Infinity Ward published daily updates on its official patch-notes page throughout Early Access. The August 24 notes marked the final full day of pre-order access and focused on increasing minimum time-to-kill for weapons including the Axion, Han 86, Kastov 762, M4, PPSh-41, and MAR-9 through shorter damage ranges and reduced head, neck, and torso multipliers.
That followed August 23 tuning to the M4 and Kastov 762, a 45% Attack Helicopter health reduction, and attachment fixes after players reported incorrect Gunsmith "Cons." August 22 addressed the loudest Day 1 complaints: enemy footstep and gear audio were reduced in volume and hearing distance, ISO Nightshade and Oris 8.6 lethality was trimmed, and shadowed areas on Transit 213 were brightened.
When do the mw4 beta dates end and open access begin?
According to Activision's August 20 welcome post, Early Access for pre-order and code holders began August 21 at 11:00 AM PT and runs through August 25 at 10:00 AM PT. PlayStation and Xbox confirm the Open Beta returns August 28 at 10:00 AM PT through September 1 at 10:00 AM PT, with no pre-order required for Weekend Two.
Install and progression carry over between weekends on supported platforms. Modern Warfare 4 launches October 23. Players who reach level 30 during the beta can earn eight rewards that transfer to launch, including the Dread Tiger operator skin and a Han 86 weapon blueprint.
Which maps and modes did beta patches add?
Day One shipped four core maps—Rooftops, Silkworm, Transit 213, and Kill Block—plus classic modes and the Mobility Course. August 22 added Cachette, enabling four-map voting, and Inflation, a cash-bounty mode where high-value targets are marked for the lobby. August 23 introduced Lotus and Gunfight 3v3 on Kill Block, alongside a Transit 24/7 playlist.
PlayStation notes six total 6v6 maps across the beta, with Ground War on Imjin Farmland and Wolves Stadium and a first-ever playable Campaign mission, Entrenched. Xbox highlights Korean Peninsula-inspired level design and new traversal options such as pipe climbs and mantle slides that patches have continued to refine.
How is Infinity Ward responding to player feedback?
The studio said spawn logic remains an active focus after analyzing large-scale beta match data, with improvements planned before launch. Known issues tracked across updates include join-in-progress disabled on Kill Block, occasional FPS drops when cooking lethals, and ongoing Kill-cam edge cases.
