Hello i have set up a account just to boost people to 50 in a matter of seconds. Msg me at FK Face Mc Gee to recieve a invite when i am on. This is the fastest possible way to level without gamesaves. I guarantee u wont be disappointed with the leveling speed.
There is a save out for this already. Also there is an editor, but at least you're helping out people who can't do it.
That's the only reason i am offering the service. A lot of people have trouble even doing game saves so i doubt they will be able to do this. I am always glad to help fellow players.
