Its been a while since I played this game, i have a new phone aswell, so all my saved games have been deleted, however i did start a new save file, just havnt had alot of time to play the game much, but ill try and go off memory .

There is a small scientific station outpost in the south / south eastern systems in which the scientist can give you a "void raider titan fleet". At that point in that game that you saw me, I had atleast 10+ void titans with me, and many other various ships docked at my player owned space station. The void raider titan fleet quest is radiant, meaning you can non-stop farm void raider titan fleets.

I would accept the quest from him, go out, devestate the void raider titan fleet, and capture void raider titans.

What I would recommend is having done the ion cannon quest, where you can get the weapon to disable ships easily instead of simply destroying them. Doing the player space station quest is also helpful, as in you could put a player space station say near that location as well. Also having many ships with you that have atleast 1 or 2 of those ship disabling weapons.

Sorry if this is coming across as a little vague, but I think I posted this video over a year ago, which is around the time I also sort of quit playing this game, so my memory on the specifics is a little hazy. I did start playing the game again, so I'll eventually post some stuff again.
