The Modern Warfare 4 early access beta crosses 10 million unique players as Infinity Ward shares its week-one data and outlines changes coming for the open beta and full launch.
The first week of the Modern Warfare 4 early access beta has officially closed — and the numbers are staggering. Infinity Ward confirmed today that the beta surpassed 10 million unique players in its first seven days, making it the most successful Call of Duty beta in franchise history by a significant margin. To put that in perspective, MW3's entire beta period — including both early access and open weekends — reached roughly 8 million players. MW4 has shattered that mark in early access alone.
Total playtime has exceeded 180 million minutes across all platforms, with the average player session clocking in at 42 minutes — a figure that Infinity Ward executives described as "well above our projections" during an internal briefing. The PDW-57 SMG has been the most-used weapon, accounting for 18.7% of all kills, while the MCX Spear assault rifle leads in overall pick rate at 22.3% of all loadouts created through Gunsmith 2.0.
Infinity Ward has not been idle. The development team has been poring over player data, forum feedback, and telemetry since the beta launched on July 10, and today the studio shared its preliminary plans for the day-one patch that will ship with the full game's November 6 release. The changes reflect the studio's willingness to respond rapidly to community sentiment.
The most significant planned change addresses Time-to-Kill (TTK) concerns. A vocal segment of the beta player base has expressed that the current TTK feels too fast, arguing that it reduces the skill gap and punishes aggressive play. Infinity Ward confirmed it is experimenting with a global health increase from 100 to 120 for the full launch, which would extend average engagement time by approximately 15%, giving players more opportunity to react and outplay opponents. "We're still tuning the exact values, but we've heard the feedback loud and clear," the studio stated. "MW4 should reward precision aim, positioning, and smart movement — not just whoever sees the other person first."
The KV Broadside shotgun is also getting substantial changes. Beta data shows the weapon accounts for 34% of all shotgun kills — an outsized share that Infinity Ward attributes to its generous one-shot kill range. The full launch build will tighten the KV Broadside's pellet spread and reduce its effective one-shot range by roughly 20%, bringing it more in line with MW19 shotguns. The weapon will remain powerful at close range but will no longer challenge SMGs and ARs at mid-range distances.
Map visibility is another area receiving attention. The "Caspian Border" map drew particular criticism for its snow-covered terrain and shadow-drenched interiors that made enemy operators difficult to spot — especially those wearing dark-colored skins. Infinity Ward has confirmed that lighting passes are underway for Caspian Border and several other maps, with the goal of improving character contrast without compromising the atmospheric lighting that players have praised. The studio is also investigating adding optional red dot outlines as an accessibility feature, similar to the system used in Valorant.
Gunsmith 2.0, which has been the beta's biggest success story, will receive quality-of-life improvements based on player usage data. Infinity Ward revealed that 42% of players spend more than 3 minutes in the Gunsmith menu per session — a figure the studio views as evidence of the system's depth, but also a signal that the interface could be streamlined. The day-one patch will include saveable weapon preset slots, improved sorting and filtering, and a "compare weapon" feature that lets players see side-by-side stat comparisons of different receiver configurations. The studio also confirmed that a mobile companion app for Gunsmith 2.0 loadout creation is in development, though no release date has been set.
On the technical stability front, Infinity Ward reported that the beta's crash rate has dropped to 0.3% of all matches — a new low for a Call of Duty beta — following the mid-week hotfix. Shader compilation, a perennial pain point for the franchise, has been further optimized. The team is also investigating reports of input latency issues on certain Xbox Series S configurations, with a fix expected before the open beta begins.
The open beta, which runs from July 17-20 across all platforms, will serve as the final major test before launch. Unlike the early access period, the open beta will feature full cross-play matchmaking from day one and will include two additional maps not yet seen in the early access rotation: the close-quarters "Bazaar" map set in an Istanbul marketplace and the sprawling "Oil Fields" map set in the deserts of Kirkuk. Both maps were originally planned as launch-only content but have been accelerated to the open beta schedule to gather additional feedback.
"We want to ship Modern Warfare 4 in the best possible state," Infinity Ward said in its official communication. "The beta data and community feedback have been invaluable. Our team is working around the clock to implement changes that will make the full launch experience everything players deserve. See you in the open beta."
