Slug I am not familiar with all of those switches but assuming he is talking single player, thats cruel!
If he was talking MP you know that "Format C:" works a lot better.
Mausman, welcome to the forum.
Just to let you know that so long as you are refering to the single player cheats or godmode that Marts has shown you how to activate, you wont be breaking any forum rules. But make sure you ignore the first part of my post and all of Slugs!
However if you are after MP cheats you will become the proud owner of a permanent ban! That is a prohibited subject on the forum.
If you need more details in getting the SP ones to work, i think they are covered in the "SP tips tactics and Spoilers" thread at the top of the General Discussion forum. Post back if you need more help.
