The level will start with Agent Coulson in an extremely delicate situation. Destroy the objects in the center of the room, one gives you the parts for a pool table, the other the parts for a shield deflection panel. Swap to Captain America and deflect the beam into the red spider looking box above (in the center of the rear wall).
Use spider-man's spider sense to detect the web spots on Agent Coulson's device. Rip him out of there and Daredevil will join you. After the Kingpin revolves, Electra will join in. Hit her three times to knock her out (pretty simple really).
Bullseye will be the next enemy to fight. Attack him to deal the first point of damage and he will retreat to a laser cannon. Attack the cannon to destroy it. Bullseye will repeat the same thing again so blow up the next cannon. Bullseye will be knocked out and the parts will be there to make web spots on Kingpin's panic room.
Pull it down and Kingpin will join the fun. Build the push panel on the left side to drop a chandelier on Kingpin's head for a point of damage. The second one can be knocked down with Captain America's shield and the third has two web spots that will be revealed by Spider-man's spider sense. Pull it down for the final hit.
