FINALLY managed to beat this on easy with the Type B Kestrel Cruiser. I was down to 1 HP for like 90% of the last phase but through careful cloak usage and, let's be honest, downright straight up luck, I was able to pull out the win. Yes, my Rockman may have been onboard the enemy ship when it blew up, but his sacrifice will not be forgotten!
All in all a memorable run, not only did I get my first win, I also unlocked both the stealth and mantis ships on that run, as well as got the third human achievement. Third human achievement was actually easier than I thought, when it said "6 unique aliens" I thought for sure that meant mantis, zoltan, engi, rockman, slug, crystal dude. Nope, apparently humans count as aliens now, only needed 5 of those plus my human pilot. Just in case anyone else is looking at that achievement boggling at the amount of luck it would take to pull it all together. Only need 3 more ships, Crystal, Slug, and Zoltan. I also learned that no matter how many missiles you THINK you have, you need MOAR MOAR MOAR for the last boss, that would have been WAY easier if I hadn't have ran out halfway through phase 1.
