In the intro level, Iron Man, Spider-Man, and the Hulk had to work
together to defeat Sandman. The boss fight was a puzzle where players
had to activate three hoses and soak Sandman with water. The puzzles
were designed so characters had to work together like Spider-Man using
his webbing to create a rope for the Hulk so he can smash a Lego
barrier. Iron Man can fly around and Spider-Man also has his
Spider-Sense which detects hidden blocks.
Lego Marvel Super Heroes pairs characters up that you may
not normally see like Captain America and Wolverine in the second level.
Captain America, of course, throws his shield and if you do this at a
wall you can create a platform. Deadpool is also confirmed to be in the
game. A staff member from TT Games explained Deadpool has dual swords,
dual guns, regeneration, and the power to break the fourth wall.
