Wondering why your first base in Subnautica 2 is all just corridors? Before you can build rooms in this submersive survival crafter, you'll need to unlock the room recipe, which can be a surprisingly big limitation early on. You're going to need space to fit your facilities, after all, not to mention anything larger like a Tadpole moonpool if you want a vehicle.
The 'Room' structure is surprisingly versatile, though. You can create bigger rooms by placing them next to each other, and even shave off little chunks to get the perfect size, assuming you've unlocked the Habitat Builder, that is.
