To play against Spider-Man, you must use Wolverine in Arcade mode, and have all perfect matches. After about half way through, after you take down your forth or fifth opponent, you will get a battle screen that says Wolverine vs. Spider-Man.
Unlock Pool Party fairly
Play Survival Mode and place in the Top Ten ranking ten times, such that the 1st thru 10th place is occupied with characters controlled by a human player. A quick way to ensure this is to pick any character and beat 1st place's # of wins and just do it 10 times. Can be done with the same character, as long as you [a human] places in the Top Ten.
