Audio problem: Times Square Off: When Doctor Octopus says "Victory is now within my reach", his mouth is wide open and his lips don't move.
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.
