These are SP mods so they are only for fun, or getting easy achievments.
I will post a tutorial how to do this when I have some time (again only for people who dont already know about this).
Just hash and sign with your ID's and use Xport to navigate to your savegame on ur xbox HDD and backup the file on the HDD before replacing it. Once that's done just load up the game and resume the SP.
The program used to make these mods is called Modio, credit goes to game-tuts.com (Program attached, tut coming soon)
