Infinity Ward has deployed a new update for the Modern Warfare 4 beta, expanding the available content while addressing ongoing feedback regarding spawn logic. The patch, which went live on August 23, 2026, introduces a new map, additional game modes, and a series of weapon balance adjustments.

New Content and Playlists

The update brings the following additions to the beta rotation:

  • New Map: Lotus is now available in the 6v6 map rotation.
  • 3v3 Gunfight: This mode is now accessible on the Kill Block map.
  • Playlists and Modes: The Transit 24/7 playlist has been added, and Search & Destroy is now available for play.

Weapon and Equipment Adjustments

The developers have implemented several balance changes targeting headshot damage and attachment utility:

  • Headshot Multipliers: Reduced for the M4, Patriot XMR, PPSh-41, Kastov 762, ISO Nightshade, X-58 NYX, FiNN LMG, Type 73, and Krait P68. Several of these weapons now also feature increased damage dropoff over range.
  • Optics and Underbarrels: ADS speed penalties for Holo, Mini Reflex, and Reflex optics have been lowered. Bipod, Launcher, and Shotgun attachments have had their ADS speed penalties removed.
  • Grips: The Angled Grip and Vertical Grip have received mobility buffs, including a 17% increase to Jog Speed and a 50% increase to Strafe Speed for the Vertical Grip.
  • General Changes: Laser attachments have been adjusted for visual clarity, while Frangible Rounds no longer provide a stun effect. The Attack Helicopter's health has been reduced by 45%.

Technical Updates

Audio cues have been remixed to prioritize critical intel, including increased volume for Kill Confirmed pickups, Domination captures, and Frag Grenade fuses. Conversely, explosion sounds on Transit 213 have been lowered. Infinity Ward noted that while spawn refinement is a priority currently in progress, they are also investigating reports of inaccurate kill cams, excessive Gunny notifications, and long countdown timers.

Players do not need to manually download or enable these changes; the patch is applied automatically upon launching the game.
