TL;DR
Crustatians (Magma Crust + Crustacean + Martian), silicate based lifeform with a resemblance to crabs, lobsters, shrimp, ispods, etc. that utilize ambush tactics and camouflage.What ?
Crustatians are a silicate based lifeforms that dwell and nest in magma. As their exoskeletons resemble volcanic rock, they excel at camouflage and often lay in wait, limbs and legs curled up to mimic terrain. Since they're slow, heavy, and lumbering, they utilize ambush tactics to get the jump on threats and prey. Once grabbed by their claws, Crustatians will scuttle back and attempt to drag you into the lava. On Vulcanus, Crab boils you.Their tough shells are resistant to firearms, and incendiary weaponry has little to no effect on them. Explosives, however, break them up real good.
You may question yourself; Was that rock always outside my factory? ... Were all of those rocks?
Why ?
Pentapod reveal suggests that new enemy species are being designed to directly confront the player in their pursuit of the planets resources. Reading into the Vulcanus reveal, it suggests slurping up lava might 'disturb' something below. A species made of rock and mineral that dwell in magma make a lot of sense, and would fill a unique niche. I imagine this is the plan already; my idea is just sharing how they may look and behave. As well as the very punny and very high quality name, Crustatians.Pointless Fluff
With the reveal of the Pentapods, I started having ideas about what we might see on other planets, based on the 'hints' in their reveals. Crustatians came to me and started really clicking, so I wanted to share it! I'm sure the devs already have something in mind, but I wanted to at least toss it out there and share.All the work going into 2.0 is amazing. Every update surprises me with more and more. I didn't expect the pentapods, they're really awesome and blew me away. Really great work y'all!
