If you are looking for saves, Xbox-saves.com is the place to go. But, don't cheat on Live or else your EEPROM (your Xboxs id) will get banned. And plus, its just not sportsman like to cheat.
P.S. You can no longer cheat w. Rainbow Six 3, before yesterday people could use moliolev ****tails but, Ubi Soft released the patch.
P.P.S. I had to get a brand new box becuase of my cheating
I don't anymore because i learned the hard way.
