Call of Duty: Modern Warfare 4 beta sees high Steam player engagement

The beta phase for Call of Duty: Modern Warfare 4 has achieved significant player engagement on Steam. Data indicates the beta reached a peak of 115,145 simultaneous players, surpassing the approximately 100,000 peak players recorded during the launch of Black Ops 7 in November 2025.

While the player numbers are high, the community has expressed mixed opinions regarding gameplay changes, specifically noting a faster time-to-death and the removal of the Omnimovement system. The full release is expected at the end of October.

Additionally, the ESRB rating for the title has raised questions regarding potential new gameplay mechanics. The rating description notes that players can kill civilians and non-combatants, which may negatively impact their game progress. This has led to speculation about the implementation of a morality system within the campaign, though it remains unconfirmed whether these consequences are a core mechanic or a standard rating disclosure.
