I've just realized that Starbound as it currently is lacks something essential, without which it will never reach its full potential. There are no bagpipes.
Found a legendary weapon in gamma sector. A tesla staff(spear) shoots little lightning bolts. Pity it has alpha sector damage, and is thus worthless.
And really, at this point you could probably kill the ufo with a rubber chicken.
I found one in X sector that does Delta sector damage, too. Looks like it's just a novelty.
The world tree is bearing fruit.
I'm going to stuff it full of chests and if I can get water in the ship, it'll be topped off. If you want my treasure you'll have to swim in my fluids.
Hey, my latest starting planet was around a star named Yggdrasil!
EDIT:Forgot I came here to ask, where can I get guns? Is there any sort of specific area that's more likely to have a merchant?
Arid, desert and grasslands seem to be the prime candidates for avian sky pirates, who sell guns. Look for an anchor and have a lot of noobtoweringblocks.
On that note, what are the coolest weapons y'all have found? Mine's still the flamethrower rifle, though in a world of 1000-2000 DPS its 60 DPS has become pitful. Still useful for lighting, though.
I don't think that the sky pirates have "preferred" biomes; I've found them just as often on moons, magma worlds, and jungles as the ones you listed. :/
My favorite is still the landmine sniper, but my 5k damage rocket launcher is pretty cool. I also picked up a mediocre green grenade launcher that shoots plasma grenades.
