Submitted to Oceanauts, a collection of "Subnautica" Leviathan observatories. See complex bases built in key places on Planet 4546B. Will the Leviathans attack these bases? Can yo go outside and interact with dangerous animals? Can you die while doing that? But of course. I winder if there are enough materials in the area to build so many windows and hull reinforcements. It is interesting to note that this player is in Survival Mode, and managed to build complex bases without being eaten!
