I lost all my stuff out of nowhere in gears of war 3. i was playing and i got off for an hour got back on and BOOM lv 1 executions GONE skins GONE everythings gone how do i get it back?

Well, first check if You're on the right user. I accidently did that with mw2 and I was seriously MAD. I think my little brother did that once as a joke.......

But as a SERIOUS ANSWER, if you know or learn how to program in whatever language the game is in, you can not only get everything back, but also cheat all skins and executions and other bull(i dont play gears), so buff up on the computer language, install a hard drive compatible with (PS3?) games, put in the disc, run the disc, find the variables section (should be about line 50 to 100) some might be under the main variable loop, reprogram the game, and put it back in (hoping you didn't totally destroy the game), just to get back some skins and kills you can probably get back in a week. In other Words, It's totally impractical. Good luck.
