The bottle cap event for Treyarch's Call of Duty: Black Ops 7 drew criticism on January 19, 2026, with players stating its leaderboard system primarily rewards extended playtime or exploiting "cheese" tactics rather than skill. Previously, on December 29, 2025, a Treyarch Design Director denied making adjustments to the matchmaking system for Call of Duty: Black Ops 7, following heated discussions within the game's player community regarding its mechanics. This followed the launch of a limited-time free trial for Call of Duty Black Ops 7 on December 16, 2025, which offered access to the multiplayer and Zombies modes on Xbox, PlayStation, and Steam until December 22.
