Modern Warfare 4 beta patch slows TTK and reshapes movement
Infinity Ward shipped a sweeping Call of Duty Modern Warfare 4 open beta patch for Weekend 2 that slowed time-to-kill on every gun, moved Tactical Sprint to the Blood Rush perk, nerfed slides, reworked spawns, and raised killstreak costs by one kill. The update lands as Warzone Resurgence on Zodiac and free open access expand the test—but Steam peak players still haven't beaten Weekend 1's 115,145 record.
Key Takeaways
- Weekend 2 patch targets TTK, spawns, movement, killstreaks, and aim assist across multiplayer and Warzone.
- Tactical Sprint is now tied to the Blood Rush perk; slide distance fell 10% and slide speed 9%.
- Every beta weapon received damage tuning to increase survivability without weakening range effectiveness.
- Steam concurrent players peaked at 115,145 in Weekend 1 and have not surpassed that figure.
- IGN's meta ranking still favors the M4, ISO Nightshade SMG, and Oris 8.6 marksman rifle.
What changed in the Modern Warfare 4 beta patch?
According to the official Modern Warfare 4 beta patch notes, Infinity Ward focused Weekend 2 on five areas: time-to-kill, spawns, movement, killstreaks, and aim assist. Rather than raising base health, the studio tuned every weapon in the beta to slightly increase TTK and give players more room for skill expression.
Movement saw the biggest philosophical shift. Tactical Sprint no longer comes by default; it moved to the Blood Rush perk, with sprint-to-fire time matching base sprint and speed cut 4%. Slides were also reined in—distance down 10%, speed down 9%, and slide-to-jump delay increased. Stamina dropped 8%.
Spawn logic from late Weekend 1 carried forward, with Hardpoint getting a prototype predictable-spawn system and Battle Hardened added to temporary spawn protection. Killstreak costs rose by one kill across the board, UAV health fell 60%, and Artillery Beacon missile counts and blast radii were trimmed.
Why hasn't the beta grown on Steam?
Eurogamer reported that despite Switch 2 support, no pre-order requirement, Warzone's Zodiac Resurgence sampler, and two new Ground War maps, Steam numbers barely moved. The first-weekend peak of 115,145 concurrent players remains unbeaten; Friday of Weekend 2 came closest at just over 113,000, likely driven by Warzone interest.
Console and Switch 2 figures are opaque, so Steam is only a partial barometer. Still, the flat trend is notable given how unusually large and fast the Weekend 2 patch was for a beta. Eurogamer noted the second session feels considerably different—slower pace, longer gunfights—but that shift has not yet translated into higher PC concurrency.
Which guns still dominate after the patch?
Weapon damage retuning reshuffles individual matchups, but early meta guidance has not flipped entirely. After more than 20 hours of beta testing, IGN ranks the M4 assault rifle as the top pick for versatility at any range. The ISO Nightshade SMG holds second despite early nerfs, offering fast fire rate and strong mobility for aggressive play on maps like Transit 213.
The Oris 8.6 marksman rifle rounds out the top three for mid-to-long engagements and quick-scoping. With Double XP and Double Weapon XP live on Day 3 and a Transit 213 24/7 playlist added August 30, players have fresh incentives to retest loadouts under the new TTK curve.
What should players watch next?
Infinity Ward framed several Weekend 2 changes—especially Tactical Sprint placement—as experiments subject to further tuning before launch.
