Post your stories about how you only try to unlock some achievement and end up beating the game in a really OP way/unlocking ship/something not related to the achievement.
Both my stories are about how I was playing the game with couple of my friends (on 55' TV screen
) and my friend just kinda challenges me to try and get some achievement.First time I just figured out I could try out Zoltan A the first time, and my friend challenged me to try the achievement "Manpower" (the one in which you're not supposed to upgrade generator until sector 5). "Shields are holding" was already unlocked, so success with this one and we would unlock Zoltan B. Therefore, I powered up my Zoltan Shield and set up on a journey.
I couldn't believe my luck. I found BL3 in first or second sector, got another zoltan from slaver, and also engi and rockman through random events. I annihilated just about every ship that tried to fight me, luckily survived couple of boarding events and upgraded my systems (though I couldn't power everything). But when I got to sector 5, I had pretty much upgraded all vital systems and had so much scrap that when I finally got to upgrade my generator there was nothing to stop me. I headed towards the flagship, armed with L3 shields plus my zoltan shield, BL3 plus halberd and leto augmented with autoreloader, and if I recall correctly, I also had teleporter and mantis and rock boarders. Flagship never truly standed a chance and boom - Osprey unlocked
. And afterwards my friend pointed out that it was a run "just to unlock that Zoltan B," in a ship named lolumad My second run was even more perfect. My friend set me challenge to get that "Artillery master" achievement on Osprey (which I had previously unlocked on my "just get that achievement" -run). Challenge accepted... From the beginning of this run, I was really on fire - again. I sent heck loads of rebels, pirates and slavers to heavenly universe, while also upgrading my artillery beam, shields and engines. Soon I got my hands on scrap recovery and repair arms - self-repairing ship achieved! Also got "Master of patience" achievement in some point, and found teleporter in shop - just what my two mantises ordered. So it was boarding time! I made killing this point, even with just L2 weapons, since I had L4 artillery beam, L4 shields and two mantises boarding if there was a chance. And again, RNG granted me with loads of weapons, so when reaching sector 5 and getting that achievement (and Fed B layout) I was after, my ship was already rebel-crushing juggernaut. Add drone control with defence and boarding drones and rebel flagship had already wet himself of sheer fear
And I just couldn't believe my luck when I got a slug from random event and headed towards slug home nebula - yes, I dare you to guess whether or not I stumbled upon a slug ship from which I managed to squeeze some information about their now cruiser... I headed towards quest beacon, tore the guarding interceptor into pieces and whoa - slug cruiser unlocked! So it was time to make rebels pay and annihilate their flagship. I tore it into pieces in a very straightforward manner. My ship took very little hull damage, and that repair arm could fix just about everything. And the best part? The ship was named in a VERY inappropriate way (because the Osprey sort of looks like male genitalia
) and it's now on high scores table - and probably is there for some time 
TL;DR:
Afterwards my friends just pointed out that in two runs with a goal of getting one achievement each run, I managed not only to get those achievements (and the B layouts) but also unlock two new ships and beat the flagship two times in a row in very very very OP manner. Good day for me I guess
