This is so fucking stupid, I hate when games do this. I still can't do it...
How the hell do you take down a zeppelin without the bird? I fired like 20 rockets into one and it did nothing. I don't get this at all...
I never once fired on the Zepplin myself. I set down electric traps all over the middle and the again up at the top where you first start. I had the songbird attack ships as they came about. Used possession on one Patriot each time they appeared. And used Undertow to pull enemies to me. They would get stuck in my electric traps as soon as I pulled them up, I would then melee them with electric punch and finish off with Charge if needed. There was never a ship that still had enemies on it once it reached the front of my ship. I pulled them all off each time. It was insane. I finished that last battle with full ammo, health and salts.
