My halo 4 freezes constantly. I have to reboot my console when this happens. It happens in campaign, in multiplayer, and in the main menus. All my other games work fine. It's just Halo 4. I've exchanged it at gamestop twice now. 3 copies of Halo 4. I'm pretty sad about my 60 dollar paperweight. I've also tried it installed, without being installed, cleared cashe, formatted hard drives, everything I can think of. I tried this with each copy, and on two different hard drives, and even without a hard drive once. Nothing works. Except all my other games.
