The final boss really requires to bring every trick you’ve learned up your sleeve. The cruiser summons fighters with Corrosion Missiles, that penetrate shields and just a couple of those can finish most ships. So my bet was on Gunship, that doesn’t have shields anyway, and plenty of hull. Front shield also helps negate some of these. Still, you need a lot of repair items, and a lot of luck. Cruiser regenerates shields quickly, and the missile flies slowly, so a few times it hit the cruiser when its shields were already up again. And you need three pairs of eyes, to watch both the cruiser with its wave of flame attack at the fighters, and their missiles, all at the same time. It’s not a fun mission, I must say.
I also finally figured out what to do on the Ancient Temple map. Turns out you can fly inside the temple and summon the Ancient, or whatever that is. Luckily, on the run I discovered this I was running a Scout with “sniper rifles”, and Okkar can’t chase you there, so you have all the time in the world to chip at this fire blob and hide behind asteroids. It’s ironic that the perk that I’ve got from achieving this task is that those Ancient Depots are shown on the star map.
