You want a sandwich? Sure. As long as you don't mind me putting poison in it.
Yeah. I use the AR, so what? All you can do is scream and rage about me using the weapon.
Once you hit "Save" instead of "Save as New Map" there's no way you can get your map back.
Also, you may have a few downloads, but there is no way too tell who downloaded it.
Edit: Yes, you should be able too but only if you haven't played another Xbox 360 game since then.
