So recently, I have been trying to get the legend achievement for MCC. Thing is, I’ve already beaten every campaign but it’s only counting everything but one level in halo 4 and all CE. The problem with CE may have been that I used bandana but I used the scarab skull and bandana for a level on halo 2 and it worked. Halo 4, on the other hand, was completely beaten and still hasn’t counted one level. I’m still waiting to see if these achievements will be awarded later. Anything that could help me?
