3. Bunker - Anita's Garden & Basic Fins

After getting the Main Habitat location from the Reception Center’s NoA, prepare for the journey.

Open your PDA Signals page to see all discovered signals. Click the dot on the left to show/hide markers; click “Edit” on the right to change marker colors (useful when many signals are active).

Since the Main Habitat is far, craft Basic Fins and Standard Oxygen Tank first. You’ll need Rubber and Silver. Rubber is crafted from Sea Crowns (grow on Cradle Bud roots on the seabed, emit orange glow). Cradle Bud roots can also be cut for fiber. Craft Basic Fins first for faster swimming, then get Silver for the Oxygen Tank.

Equip crafted items by opening PDA, going to Inventory, and dragging items to body slots.

Silver is far from the lifepod. You’ll encounter toxic sponges. Prepare water, Three Moon Fish Wrap, Basic Medkit. Craft an Air Bladder (Rubber x1 + Titanium x1) — great for emergency oxygen or fast ascent. The bladder itself isn’t consumed, but the air inside is; it auto-refills in oxygenated areas.

Head NE 45 from the lifepod about 90m. Find metal wreckage exposed above water. Enter the cave near it — swim on the surface first, then dive.

At the metal wreckage entrance, there’s a cave with a downward current. This is one-way (down only). Refill oxygen fully before entering.

Follow the current to the bottom. On the left, bubble plants provide oxygen; there’s also an oxygen pocket above them. Head toward the table ahead, and continue past it.

Scan Underwater Propeller Module 1/3 and Flashlight 2/3 at the table. Open the box for a Basic Battery. There’s also a Portable Locker to carry.

From the table, look NE. Find a cave entrance with blue light — enter it.

Follow the tunnel, take the right fork at the blue light, arriving at Colonist Bunker (Anita’s Garden).

Inside the garden, scan items (Stool, Trash Can, Single Bed, Bio Bed). Download data from the trash can, then use the Bio Bed for an endurance boost.
