Ok, for starters this is a cheat the SUPERCHEATS STAFF has entered incorrectly, for the ALTERNATE COSTUMES they say to do it at the CHARACTER SELECT screen, when infact you do it at the MAIN MENU screen, the cheat is up, up, right, left, down, down, start. Then go to a Xtraction Point and prees X to change costumes (some characters may not have alternate outfits).

Another thing the SUPERCHEATS STAFF has left out is how to play as Magma, you have to complete her second training session with Proffesor Xavier.

Hope I helped all the people who were running 'round in circles cause the cheat didn't work.
