BLACK OP MASTER is a campaign achievement/trophy in Call of Duty: Black Ops. It is unlocked by beating the campaign on Veteran or Hardened difficulty.


  • This achievement/trophy is confirmed to be bugged on both Xbox 360 and PS3, in that it does not unlock even after completing the campaign on Veteran or Hardened. This is caused by using the "Save and Quit" feature during a mission and continuing it later, and that re-completing any missions which were exited halfway through will unlock the achievement/trophy. Treyarch has not yet fixed this problem.
