I’ve completed all campaigns on legendary on mcc, why have I not yet received the legend achievement?

Try looking to see if the achievement is 100%. sometimes achievements don’t show for me either.

Hey OP, the following levels aren’t showing as being completed on co-op legendary for Halo CE

  • ASSAULT ON THE CONTROL ROOM - 343 GUILTY SPARKI believe for the legend achievement you need to complete all the campaigns either co-op or solo, it can’t be a mix of both. If you do those 2 levels again it should unlock for you.
