Call of Duty: Black Ops is a 2010 first-person shooter game developed by Treyarch and published by Activision. It was released worldwide in November 2010 for Microsoft Windows, the PlayStation 3, Wii, and Xbox 360, with a separate version for Nintendo DS developed by n-Space.

Players still want to relive the Call of Duty: Black Ops multiplayer experience 13 years after its debut. However, they were unable to find matches due to service difficulties. Activision has recently deployed server fixes to reduce these issues, significantly increasing the number of people actively playing the game.
