Foundation
The stable platform every seabase starts on. Adds hull integrity and anchors corridors and rooms.
Corridor (X-Tunnel)
The connecting passage that links rooms and foundations into a navigable base layout.
Multipurpose Room
The main interior space for fabricators, storage, filtration, and other base equipment.
Hatch
The entrance and exit for your seabase, letting you pass in and out underwater without flooding.
Solar Panel
The primary early-game power source, generating electricity from sunlight to run your base.
Water Filtration Machine
Purifies seawater into large filtered water bottles for reliable hydration at the cost of power.
Recommended Build Order
A typical first base follows this progression. Start with a Foundation, add a Room for equipment, mount a Hatch to get in and out, then power it with Solar Panels and add a Water Filtration Machine for hydration.
