Continuity mistake: When Magneto crashes through the roof of the Baxter Building, there is rubble all around him. There is a rectangular shaped white piece of rubble directly in front of Mr. Fantastic. That piece of rubble vanishes as Mr. Fantastic leaves to go get a broom.
Continuity mistake: Taking Liberties: Partway through the level, The Hulk, Mr. Fantastic and Wolverine will have to go into a lift. When the lift reaches the second level, all of the positions of each person in the lift have been reversed. They are completely different to when they entered.
Continuity mistake: After completing "Juggernauts and Crosses", it will show the Fantastic Four outside Baxter Building. The Thing and The Human Torch will then run off, leaving Mr. Fantastic and the Invisible Woman. The two will then go to Central Park and get in the Fantastic Car. When they get into the shuttle, it is still just them, but when the intro clip for "Doctor In The House" starts, The Thing, The Human Torch and Nick Fury have appeared in the shuttle from nowhere.
Continuity mistake: Rebooted, Resuited: Tony loses his pants in "Rock up at the Lock up" and doesn't have them when he returns to Stark Tower, but he suddenly has his pants as soon as the intro clip for "Rebooted, Resuited" starts.
Continuity mistake: Sand Central Station: Abomination is thrown through a station window and the glass flies out as he is thrown through. No glass is shown on the ground.
Continuity mistake: During the intro clip, one shot shows Tony inside his suit with blonde hair. Later on during the intro clip for the "Sand Central Station" level, he is shown inside his suit with brown hair.

Chosen answer: Captain America has a shield. Use his shield to deflect the blasts from the turret and it will bounce back at the turret destroying it. Left over from the turret is a piece of rubble. Switch to The Thing and have him throw the piece of rubble at the part of the wall that is glowing. This will uncover a target for Captain America to throw his shield. Switch back to Captain America and have him throw the shield at the target. The electric gate will be disarmed after this.
