Ulitmate Alliance Codes
These codes have to key-ed in in a relatively quick succession. The text in the brackets describe where they have to be entered. Some codes require that you press start at the end (you should hear a sound effect if you entered the code correctly) while some require that you enter them 2 to 3 times before they work. I havent fully discovered all of the codes in the game yet.
