The second beta weekend for Call of Duty: Modern Warfare 4 opened the game to everyone, and the Steam data tells a mixed story. Player retention held up far better than the first weekend, yet the peak concurrent count did not climb and the review score stayed exactly where it was.
Quick answer: The Weekend 2 Open Beta peaked at a little over 113,000 concurrent players on Steam, roughly 2,000 below Weekend 1’s ~115,000, but it kept close to 100,000 players in its first 24 hours instead of collapsing toward 60,000. Steam reviews remain “Mixed” at 45% negative, unchanged from the previous weekend.
Modern Warfare 4 Open Beta Steam player count (Weekend 2 vs Weekend 1)
The full Open Beta went live on Friday and was available to all players with no pre-order needed. Despite that wider access, the concurrent-user (CCU) peak did not set a new high. It topped out a bit over 113,000, which sits about 2,000 below the roughly 115,000 the Early Access weekend reached when far fewer people could get in.
Where the second weekend clearly improved is retention. The beta held close to 100,000 players in its first 24 hours, a much steadier curve than the previous weekend, which had already fallen toward a 60,000 peak in the same window after losing nearly half its players within a day.
| Metric | Weekend 1 (Early Access) | Weekend 2 (Open Beta) |
|---|---|---|
| Steam peak CCU | ~115,000 | ~113,000 |
| Players after ~24 hours | ~60,000 | ~100,000 |
| Access | Pre-order or beta code | Open to all, no pre-order |
A drop-off is still visible, but it is far milder than the first weekend’s steep fall. Some tapering is normal, since a chunk of the player base logs early hours and then moves on. It is also worth remembering that these figures cover Steam only, which is the single platform where concurrent numbers are publicly visible. Console and other PC storefront counts are not tracked the same way.
Modern Warfare 4 Open Beta reviews stay Mixed at 45% negative
The one figure that did not move is player sentiment. The Open Beta carries a “Mixed” rating on Steam, with 45% of reviews negative, the same split recorded during the first weekend. That consistency suggests reception has not shifted much even with a larger and more varied player base, and the complaints echo those raised earlier.
Note: A “Mixed” tag on Steam covers any title where a meaningful share of reviews are negative, so the score reflects a divided response rather than an outright rejection. Retention improving while the review split holds steady points to two separate signals worth watching ahead of launch.
Open Beta schedule and platforms
The Open Beta is the second of two beta weekends. Unlike the Early Access period, it requires no pre-order and adds Nintendo Switch 2 to the platform lineup. Full details on downloading and launching each version are on the official Modern Warfare 4 Open Beta overview.

Infinity Ward has been pushing tuning changes between and during the weekends, including adjustments to movement speeds, weapon handling, and client-side stutter. That ongoing patching is the reason the numbers are worth reading as a snapshot rather than a verdict. Retention that holds near 100,000 on Steam is a healthier sign than the first weekend produced, but the flat review split shows the same feedback still stands. Whether that feedback shapes the game before it launches on October 23 is the open question the beta leaves behind.
