Since Friday, I've been playing Halo on my Xbox 360, but I'm recently running into trouble. I've been passing several checkpoints from a part of the Assault on the Control Room, and stopped after the checkpoint was saved for the Super Weapon level. But when I booted up my 360, that progress was nonexistent; I was back where I started. Did I do something with the options, or is something wrong? Help me, GAF. You're my only hope.
