Hint: Unlock all characters and venues easily:
Every ten versus battles unlocks either a venue or a character. The easiest way to do this is on the bridge level, with a second controller. Throw your opponent off the edge of the bridge for an easy victory.

Use Spider Man's web throwing move against any enemy against an idle player two. Keep selecting "Rematch" to speed up the process.
Rockmanneo12.

In versus mode, start by using The Thing and keep fighting Wolverine. Once you unlock Venom, start using him. Use his Web Toss with your back to a wall. This best done at the Daily Bugle because of easily breaking walls. You will unlock Venom after seventy versus matches. Also, set your lives to five (or more if you are a beginner), and set your enemies lives to one.

Hint: Handsprings:
With Spider-Man, Daredevil, Elektra, or anyone else that does handsprings for a dodging move, hold Y and press Left Analog-stick Away or Left Analog-stick Forward. Keep tapping in that direction and your character will keep doing handsprings.
Flick Montana.

Hint: Easy finishing moves:
This works easiest when you are in Rage mode. Once in Rage mode, damage your opponent down to danger. Then, try to get next to your opponent and do a Super Block (R + Y) to knock them off guard. Then, quickly press R + B to do the finishing move.
