X-Men: Reign Of Apocalypse Codes -

Hint: Special move:
Press A + B to do a special move. Note: This takes away a little bit of life.

Press Attack + Down/Left. Note: This results in a different move for each character.

Hint: Defeating Night Crawler:
Knock Night Crawler onto the spikes that appear from the floor. Keep punching him, and the spikes will help kill him quickly, often without hitting you back.

Hint: Cyclops:
Choose Cyclops when selecting a character. He has no punch combo, so you can continuously punch one enemy till he is KOd without having to stop, unlike the other X-men who can only punch three or four times. Note: This will not work on most Bosses. mini-Bosses and Sentinels.
