The Call of Duty: Modern Warfare 4 beta set a new record on Steam with 115,145 concurrent players. This number exceeded the Steam online peak of around 100,000 reached by Call of Duty: Black Ops 7 at its official launch.
According to SteamDB data, this test lasted for 17 days and ended on September 1. Since the test has concluded, it is no longer possible to monitor its daily or weekly active user data, but the highest concurrent player count during the test period has been confirmed.
Call of Duty: Black Ops 7 launched in November 2025, attracting around 100,000 concurrent players on Steam during its initial release. In comparison, the peak for the Call of Duty: Modern Warfare 4 beta was approximately 15,000 higher, a figure achieved during a limited-time test rather than the full official launch.
The test content has also sparked discussion among players, with focal points including faster time-to-kill and the removal of omnidirectional movement mechanics. However, the long-term impact of these gameplay changes will only become clearer after the official release.
It is important to note that both figures only reflect the Steam platform. Call of Duty: Black Ops 7 is also available on PlayStation, Xbox, Battle.net, and the Xbox PC app, so the Steam peak does not represent the game's overall player base across all platforms.
Based on current Steam data, Call of Duty: Modern Warfare 4 has already surpassed the launch peak of Call of Duty: Black Ops 7 during its testing phase. Whether its official release can maintain this level of online engagement remains to be seen as more data becomes available.
