Exactly what it says on the tin. List your ship. Your weapons. Your crew.
Honestly, the worst loadout I've had was on the Noether. I had nothing but Slugs. All my crew died aside from the 2 Slugs I had. Slugssssssss. Uselessssss. And guess what my weapons were?
Yeah.
Mhm.
*cries* HEALING BOMBS. AAAAH.
I was forced to board...
I actually won that one - my consistent failure to find or score ANY weapons at all other than Basic Lasers got me to invest in drones, teleporter, cloak, etc. Ridiculously long, tough fight aimed at using Manti boarders to knock stuff out, but well it worked! The Basics took the Flagship down when it had only a HP or two and the boarding crew had...somehow...damaged the shields enough.
I'm still not entirely clear on how all of that worked.
