I’ve never fought with spaceship sentinels much, so I’d thought I’d give it a try. I went all out, maxing out the alert level, or whatever it’s called. Everything was pretty easy. Until this bad boy warped in, with all it’s weapons pointed on me. 
Covered in lasers and turrets, navigating around it in my beginner ship while avoiding/fighting the smaller ships, this capital ship put the pressure on in the battle.
Once I understood its attacks and timing, it was so easy to take down, I did 2 more on my way to the space station. Got some decent loot from the ordeal, if I had a fleet to use it with anyway, and sold it off at the trading hub.
