LEGO Marvel Super Heroes -
At the beginning of the mission you will be forced to fight with huge army of Magneto Acolytes. They will flow in endlessly - you must stop them in some way. To do that, switch into Spider-Man and use his spider sense on the wall located on the right side of the room. Uncover two attachable points, then yank them with your web, uncovering a silver plate in this way. Destroy it using Iron Man's rockets, then choose Thor and charge the battery.
Turn left and look for the another silver wall. Blow it up, then charge second battery as Thor. After that build a lever from the debris and rotate it to open the door.
