Revealing mistake: Red Head Detention: Just after you reach the area where Red Skull is first shown to be located, walk over to a device with tracks leading into it. If you walk straight up to it, the floor design's colour changes and the shadow of some objects appear from nowhere.
Revealing mistake: S.H.I.E.L.D. Hellicarrier: If a character falls off the Hellicarrier, a rescue drone will rescue them. On some occasions, the drone will fade through part of the Hellicarrier, depending on where you fall.
Revealing mistake: Baxter Building: After letting Captain America out of the park gate and Captain America breaks the Shield Switch on the wall with his shield, a ladder will drop. If you climb the ladder, the shadow of an air conditioner instantly appears on screen. There is no air conditioner as you start to climb.
Revealing mistake: Baxter Building: Just as Captain America and Mr. Fantastic are about to land on the ground after jumping off the Helicarrier, Captain America's shadow doesn't match up with his distance off the ground.
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.
