I don’t know if anyone else is experiencing this problem but, for me Halo 3 Forge and Custom games wont load. I can select all the various options to set the game up but when I hit ‘start’ it flicks over to a picture of the level I have chosen, the little loading icon bottom right of the screen continues to spin and the loading progression bar doesn’t move. It stays the solid black colour. I have been waiting close to 5 minutes and no change. I actually have to go to the dashboard and quit the app to get out of it. It also doesn’t matter what map I choose - same thing. It only appears to be Halo 3. Halo 1,2 and 4 I can play Custom and Forge games just fine.
If you have any information or possible solutions please let me know - I want to hunt down these skulls.
