Spawn: In the Demon's Hand Cheats

Depending on how many times the game was beaten, you might have noticed a screen that says that you can go through the extended storyline with multiple players. If that happens, when next time you play, hold down ALL of the buttons, including the start button. Insert the coins, and press start while holding the rest of the buttons down. If done correctly, the screen should turn blue and an expanded character ring will appear with the following new additions.
Spawn I
Spawn IV
DA *Dark Ages* Spawn
Admonisher
