Smash the neon signs in Times Square by jumping towards them and using a tentacle attack or by throwing cars at them. Smash a few signs and then pick up cars and throw them at Electro. Try to smash as many signs as possible, as Electro uses them to recharge. When Electro goes near Spidey, throw cars at him. Also, bust open the fire hydrants to cause water to shoot out, as the water will harm Electro. Once all of the neon signs are smashed, throw cars at Electro until the battle is over.
