My halo 3 disc can play everything like matchmaking, custom, and some

[pet]

cmapsign, but i can't load the ark!!! I think it is most likley a scratch on the disc, is there a way to fix this without returning it?

I have heard of hastings resurfacing, does it work for this?

look at the disc and see if it has a scratch on it.

if it does can try something to restore the cd if it does not work ur out of luck bro.

or go rent the game from a game store and swap em out lol
