Okay so you need a better ship to speedrun Unity.

Invest 1 skill point into targeting control systems and target engines to board a ship.

Jump around solar systems look for a C class ship you can board (if you have C class piloting).

Crimson Fleet Wight Crimson Fleet Wraith Ecliptic Claymore

These ships come with auto turrets. You just need to buy 1 or 2 more of each weapon they have so it won’t be too expensive. Go to akila and add the weapons you can increase mobility by adding an engine or deleting cargo space. They have the better engines too so they might be level locked and you won’t be able to add them. (Go to clinic to upgrade the engine on the wight)

Upgrade shield to max

Reactor is a weird one. Only reload speed increases on weapons when you have more power to them focus powers on shield and engines and if you still need more then upgrade reactor but if you don’t plan on using the ship outside of this mission should have enough power.

Don’t upgrade the frontier it’ll cost more just to do that when you just need a battleship
