Start with the prologue, survival tools, Digestion, Welcome Center and a powered first base. Then follow Heat Tolerance and the Tadpole Pens to the Alien Ruins, where Axum Vision and the Power Plant lead to the Observatory story sequence.
Updated .
This is the short, practical route chain for a new save. Each step links to the detailed guide when you need screenshots, exact room order, recipes, or hazard notes.
Leave the tutorial with PDA, NOA, oxygen, Pressure Tolerance, basic supplies, black box recovery, biological bed, and Launch complete.
Follow the prologue prompts in order instead of rushing outside. The important part is getting your survival systems online before the first real dive.
Next: Once Launch finishes, use the World Tree and compass as your first orientation anchor.
Build the early routine: save, pin recipes, gather Titanium and Quartz, make the Scanner, craft Water, and start mobility upgrades.
Keep loops short. Basic Battery, Scanner, Water from Water Slug, Basic Fins, and storage discipline matter more than a long sightseeing swim.
Next: After the Scanner and basic comfort are handled, move into the Flashlight fragment route.
Scan the Lifepod cave fragment and the northeast wreck fragment, then craft the Flashlight before dark caves become routine.
Use the Lifepod cave first, then take the northeast wreck route. Monitor oxygen and avoid threats, then craft the tool back at a Fabricator.
Next: With visibility fixed, follow the Anita black box route to the Angel Comb.
Fix Digestive Incompatibility so local fish, Oily Salad, Coral Mash, Halfmoon Jerky, and similar food become useful for hunger.
Read Anita in NOA, swim northeast toward the black box signal, interact with the Angel Comb, confirm Digestion, then collect Anita black box below it.
Next: Now you can support longer trips without relying only on starter food.
Swim southeast at about 150 degrees, scan the Habitat Builder fragments, restore power, and choose your first biomods.
Bring Scanner and one spare Basic Battery. Scan Habitat Builder, Dining Table, Biolab, both wall lights, and New Life Poster, then use the battery terminal to power the facility.
Next: Do the southwest wreck immediately while you are already positioned near the Welcome Center.
Start the vehicle chain and reveal Power Cell plus Strong Acid planning before returning home.
From the Welcome Center, aim southwest between 210 and 240 degrees. At the shallow 25m wreck, scan Dive Elevator, Beacon, and one Tadpole fragment, then open the nearby supply crate.
Next: Return home, gather Titanium on the way, and craft the Habitat Builder.
Turn the Welcome Center route into a real, powered first base beside the Lifepod.
Craft Habitat Builder (2 Titanium, 1 Glass, 1 Basic Battery, 1 Copper Wire), then build corridors by the Lifepod, add a Hatch, power up with Solar Panels, and place a Fabricator with Wall Locker storage.
Next: Build the Sonic Resonator, unlock Heat Tolerance, then follow the Tadpole Pens and Alien Ruins route below.
Bring Scanner, one spare Basic Battery, enough Water, and a little food. If you already unlocked Digestion, local food becomes much easier to use.
Surface first, then enter. The route is short, but the interior, cave oxygen stop, power terminal, and Biolab pick are cleaner with full air.
Treat the deep seep near the southwest wreck as a quick look. Use Dash with W plus Left Shift to move forward, and keep Air Bladder ready for emergencies.
These recipe searches are the ones that turn the route into a first base instead of another scouting trip.
Follow a short first-hour loop: use the World Tree and compass, open storage, pin recipes, gather nearby Titanium and Quartz, make Scanner and Basic Battery planning your priority, craft Water, then move toward Flashlight and Angel Comb.
Go after the basic first-hour setup, Flashlight route, and Angel Comb Digestion gene if possible. Bring a Scanner and one spare Basic Battery, then swim southeast at about 150 degrees from the Lifepod.
The Angel Comb route unlocks Digestion, which makes local food useful. That makes the Welcome Center and southwest wreck follow-up easier because hunger is less fragile.
After the Welcome Center, swim southwest between 210 and 240 degrees to the nearby 25m wreck. Scan Dive Elevator, Beacon, and one Tadpole fragment there.
Craft Habitat Builder first: 2 Titanium, 1 Glass, 1 Basic Battery, and 1 Copper Wire. Glass needs 2 Quartz, and Copper Wire needs 2 Copper.
Restore the Research Station and prepare the Modification Station, Feedback Resonator and a depth-ready Tadpole. Clear the three branches and center of the Alien Ruins Angel Comb for Axum Vision, activate the lower console, repair the Power Plant turbine, finish the green control-panel sequence and enter the Observatory from its west side.
A powered base is the beginning of the next supply loop. Prepare the mining tool and environmental adaptation before taking the longer story route east.
Return to resupply between these stages. The Zip cave swim and the later gorge crossing need separate oxygen, repair and battery budgets.
The next objective is restoring power to the Observatory. Use the Research Station as a supply stop, then complete these stages in order.
The May 2026 Early Access walkthrough ends with this Observatory sequence. The roadmap tracks announcements for the next story expansion.
