After me and a friend beat Halo 4 on Legendary, the Legendary Ending kinda bugged out...
After Master Chief took off his helmet, his eyes didn't show.. At first i thought that it was supposed to end a mystery that in Halo 5 we would see his face, but when i went on Youtube and the Forums i realized that his eyes were supposed to show..
My brother tried the ending again with his friend and the same thing happened, no eyes..
I dont know if this is a bug in Co-Op campaign or what.. Please look into this bug 343.. Thanks
BTW: Campaign was AMAZING!!!! Nice job 343
