The new modular building system in Subnautica 2 is WAY deeper than it first appears, and after spending my first week building a massive leviathan observatory base, I learned a ton of tricks the game barely explains.
In this guide, I cover room expansion and shrinking, hallway customization, window variants, moon pool layouts, interior walls, decorating tricks, tunnel designs, and a bunch of other building tips I wish I knew sooner. This is just the beginning, but if you’re diving into base building in Subnautica 2, these tips should save you a lot of confusion and help you build way cooler bases faster.
Expect more advanced building guides, modular base tricks, and mega base shenanigans soon.
