In Arcade or Play Now mode, you can finish your opponent off with an awesome finishing move. First, g your opponent's health down very low until the two "fists, webs, electric balls, syths, etc." on the touchscreen are blinking. Hit the one that is blinking, then hit the other one (only once). Your character will kill your opponent in a red haze. Note: This trick may not work on some of the characters, but definitely works against Elektra, Dare Devil, Human Torch, and Spider-Man.
On the Danger Zone level, a person can walk through the big "4" into the Danger Zone. Once in the Danger Zone, character that are thrown off the cliff towards the screen will be dealt damage, then respawn and be launched off the cliff again; taking more damage. This will continue until the character is dead.
