At the request of a few visitors, I have moved all things Gamerscore to their own category out of cheat codes, so that they are easier to find and use.
This means that Google and other search engines might have to reindex some of the information on the site, so if you are looking for Gamerscore information, please click on the category which will give you a full list of the Gamerscore posts, or use the search including the title of the game you are looking for, as well as the word Gamerscore.
