I use the wings, range enhancer/cluster missiles, the charge gun (you get on level 1 with the glider, its on a plataeu surrounded by 6ish spider tanks) and energy shield.
Stand ontop of the hill you start on, shoot, use shield to deflect the lasers while you continue firing, use glider to escape hill when it starts raining cruise missiles. This way gives you maximum shooting time. Glide to the beach, drive along it, wait for TW to stomp over, drive back up to the start and repeat.
When his turrets explode, Energon flies out. Destroy all laser and missile turrets and he starts doing a questionable manouvere as flying drones come at you.
For an added fun move, go to the top of the outcrops on the other side of the map (you can walk/drive to them without getting too deep) and let TW wonder over to you. But for some reason, this doesn't work for the two outcroppings connected by the beach.
