Oh I wasn't suggesting I should have attacked them (the ship was 10 times the size of mine!) But I wondered what was the intent of that set piece. Should I have been scanning the wreckage? Of would the Thargoid ship have blasted me out of the sky if I'd hung around?
I was a Thargoid hunting main last time I played, (it's all I did) it took me probably a week to get the correct ship build, (engineering grind. But honestly - my first experience taking on the first one, was one of the best gaming combat experiences I ever had, man it was intense - took me 40 minutes to kill it, and I only just got out alive.
I don't want to spoil it for you, but if you're going to investigate the Thargoids, you're going to need to be kitted out otherwise it'll be costly. You'll need some specialist weapons (remote flack and guardian gauss cannons) you don't need the biggest ship, my anti-thargoid build, is a shieldless krait-mkII.
You'll also need to learn to fly with assist off, and to cold orbit. I learnt most of this by killing the system authority anacondas in anarchy systems, just practise. Interdict them, kill them - kill the reinforcements until they send the advanced tactical response guys, who are basically invincible
Unfortunately to get the correct equipment it's a really awful grind, I'd recommend watching some of the youtube videos on how to do it the fastest, but it feels like Frontier never played their own game in regard to the grind, it's really not fun. Which is a shame as I feel it's an unnecessary barrier to one of the more awesome aspects of the game.
