Kombat Kodes are entered on the loading screen of two player matches. Each player can cycle a set of three icons by tapping buttons on his controller. The numbers below correlate to each player's three icons and how many times the icon must be cycled.
Example: To activate the "Armless Kombat" Kode, both players much cycle the left icon nine times, and cycle the center and right icons once each.
Some Kombat Kodes require both players input their codes, while others work even if just one person inputs the kode.
