I’ve been trying to finish the campaign co-op on heroic with an extra controller these few days until i finished the last mission just now. The issue is that Bromageddon achievement didn’t unlock for my main profile. It only unlocked for my second controller’s profile. I’m so pissed! I just checked my service record on here and it shows that i only completed 6 out of 8 missions for co-op which is so odd! I’m pretty sure that i did them all.
The thing is that i can’t see which two missions I’m missing because I don’t have xbox live gold. Can someone please check which missions I’m missing from the halo waypoint app or something? I would be forever grateful!
Update: after a while i figured out how to check my stats on this website… Found out which missions i needed to finish on heroic… AGAIN. I did that and now my co-op campaign is complete in Heroic BUT the achievement still didn’t unlock. Someone please tell me what to do??? I’m pissed & desperate!
