Just finished campaign on heroic difficulty while co-op(every mission) and sitting with legacy, heroes rise, AND all for one achievements still locked. They all say 93% complete but if I go into my co-op campaign list, every mission says completed on heroic.
im the most sarcastic way possible… Thanks for all the support here! Buy every halo game ever made and can’t even get a RESPONSE from support for one question. Losing a customer here.
