At the moment, Call of Duty: Black Ops Cold War has 2,012 concurrent players online and in-game. This is 46% lower than its previous all-time peak of 3,693 players achieved on 9/24/2024.
The campaign is good but the always online requirement and the occasional cheater in multiplayer can make things a little annoying. People definitely still play it though. Wait for a major sale. If you like zombies and campaign its great.
