Blob, but you can build walls, turrets engines etc, and you are basically living, constantly growing ship
edit:
to expand on the idea, im thinking of couple of thing you can do as this blob
walls: two types of walls maybe more
- hardshell which is very protective
- fleshwall which is fairly weak but it will regenerate if not destroyed completely
organs:
basically ship components
- gyroscopic organ
- power generating organ
- resource generating organ
- thruster organ
- special strain organ: organ that generates strain related stuff
etc
turrets:
light spitter
medium spitter
heavy spitter
special Spitter
tiny spitter that attacks boarders, really fragile
anti boarding tentacle that catches/smacks and holds the boarders in place so tiny spitter can hit em
special spitter will do something according to chosen strain
strains:
using generated points you can choose a strain, this will change properties of your stuff for example: you can choose emp strain that allows you to fire emp blasts with special spitter, and you will use special organs to generate ammo for it
other strain would fire homing boarding pods that infect other ships, special organ generates simple mobs
maybe a shield generating and fast regenerative strains
etc
ship interior and boarding:
im thinking about having organs and things having be powered by veins, they basically work like cables but they have to be coming from your core which will allow for natural made corridors
resource generation:
you will obviously passively generate some points but your main income would be any matter, your job is to consume as much as you can and grow
lore:
you can probably tie it to chimeras as their flagship/hivemind overlord or whatever they are
