My strategy: Use the ledge on the end where you came from (you can walk up it and have a clear view of the tower) as much as you can. Set fuzzle traps at the base of the path, use the top to take care of the nailers in the clear area past the ship, and hug that cliff wall tight to avoid being seen when going for more ammo.
Use Boombats for the nailers. Avoid loud ammo for the most part, like Stingbees. If you are spotted, go lower down the ledge until you can't see the tower, because they won't see you too.
