Base Building Materials

Core connecting piece for bases. Links rooms together and provides walkable space.

The most fundamental base building block. Build these first to connect modules.

Stabilizes base on uneven terrain. Increases hull integrity.

Essential for bases on slopes or uneven seabeds. Dramatically reduces structural weakness.

Entry and exit point for base. Required to get in and out.

Every base needs at least one hatch. Place hatches where you resurface most often.

Allows visibility outside the base. No structural benefit.

Purely cosmetic/practical. Great for monitoring surroundings.

Scans for nearby resources and creatures. Invaluable for finding rare materials.

One of the most useful base modules. Range upgradeable with Camera Drones.

Crafting station for all tools, equipment, and materials.

Install this in your base ASAP. Far more convenient than using the starting pod.

Wall-mounted storage for base. Each holds several stacks of items.

Build many of these. Poor storage organization is a constant frustration in survival games.

Automatically generates medical kits over time.

Passive health restoration over time. Install it and forget it.

Provides renewable power in shallow, lit areas.

Best early power source. Effectiveness decreases below ~200m depth.

Converts organic matter into power. Useful at depths where solar fails.

Fill with plant samples and fish eggs. Great passive power for mid-depth bases.

Generates power from thermal vents. Essential for deep bases.

Required for deep-sea bases. Place adjacent to thermal vents for maximum output.

Vehicle docking bay for Seamoth/Prawn suit. Allows vehicle customization and charging.

Must-have once you get a vehicle. Recharges power cells passively.

Allows installing upgrades on docked vehicles.

Place inside or adjacent to the moonpool. Required for depth upgrades.

Upgrades tools and equipment to higher tiers.

Unlocks the second tier of most tools. Essential for mid-game progression.

High-output power source for large late-game bases.

Needs reactor rods made from Uraninite. Extremely high power output.
