It wasn't anything special score wise, but I just had, probably, the luckiest run of FTL I've ever played.
Started in the Red Tail. Things went normally for a while, found a burst laser II and a hull laser I. Noticed I had a mantis homeworld up next, and having not unlocked the mantis cruiser yet, upgraded my medbay to prep. I'd already purchased a teleporter early, which I used to rack up some good scrap. Ended up getting lucky enough just as the rebel line pushed towards the end of the sector I found the thief's ship, did what I needed and got the mantis cruiser. Pushed on, found the pod. Thought to myself. "I can't be lucky enough to finish this off this late", but worked towards it anyway. Collected another hull laser I and a small bomb (never to be used although equipped to the end). I'd been racking up a lot of scrap by this point, holding it, somewhat stupidly for stores. Purchased a few decent upgrades... such as a nice pre-igniter and auto reloader. At some point I'd also found the engi med dispersal unit which was very handy. Next to last sector... Rock Homeworld... I'm panicking, I've only reached this far in the crystal quest once before... I pushed on, searching desperately for the beacon, when... yes! Found it!. I ran through the crystal sector, straight to the quest, and straight out. Only hit one fight and one store. Probably missed some stuff, but I don't care, I'd unlocked the cruiser! Left that place, and hit the last stand. Breeze through the first two forms with only one hit of damage taken. Final form hit me a bit harder, but I never dropped below 2/3 hull, and I had a hull repair drone to back me up, which I never needed.
Very happy with that run. Now all I've got left to do is the slug cruiser.
