I return to my Halo 1 Anniversary edition, to finish the “Keyes” mission, and it load a black screen. At first i just thought it locked up but i could hear the music and we able to fire my gun, throw grenade, etc. When you quit the game, it flashes for a second and you can see the game. I tired loading from “last check-mark” but same thing, and i didn’t want to “restart” the level because i was at the very end where you lead Keyes off the alien ship. I came back a few days later and still same issue. I am also playing H2A and not having any issue continuing where i left off in the campaign mode. I would really like to finish the game, please help! TY!!
