WE ARE NOT RESPONSIBLE IF YOU GET BANNED OR YOUR GS GETS RESET TO 0. MAKE SURE YOU READ THE TUTORIALS. DON'T ABUSE THE GAME SAVES OR YOU WILL GET CAUGHT. DON'T EVEN GO AND GET 5,000 ACHIEVEMENT SCORE IN ONE DAY! IS ALWAYS GOOD TO TEST GAMESAVES ON A BACKUP PROFILE So you know how to resign certain games to your xbox live profile correct? If you do that correctly, you can plug it directly back into your 360 but you have to be careful about what achievements unlock. Example: your save has a ranked wins achievments of 20 and you play an onine game, 9/10 times you will pop all the achievments prior to that all at once, which may seem suspicious. So times certain achievments will unlock after you have a set amount. Like say you have 500 and a save unlocks 550, you can complete it to get the 50 or more. Its best to check to see what achievments unlock and compare them to your list. And yes you have to have the games in the xbox to unlock them using gamesaves.
