BLACK OP MASTER is a campaign achievement/trophy in Call of Duty: Black Ops. It is unlocked by beating the main campaign on Veteran or Hardened difficulty.
Tips
- It is recommended to play the campaign on Hardened, and unlock the achievements/trophies for completing the sets of missions on Veteran, on another playthrough due to a glitch explained in Trivia section (for example, Cold Warrior requires the player to complete the "Operation 40", "Vorkuta" and "Executive Order" on Veteran).
Trivia
- 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 half way through will unlock the achievement/trophy. Treyarch has yet to fix this glitch.
