The Last Caretaker: Eden Cradle Complete Mission Walkthrough

Eden Cradle is the Seed Vault that arrived with Update 04: Below Us, sitting on the eastern edge of the map at coordinates 167, 34. No Navigation Beacon reveals it, so you have to sail there yourself — head northeast of Exodus Station and the white offshore structure eventually breaks the horizon. The quest itself is short on paperwork and long on wiring, dark corridors, and Rollers.

Quick answer: Power the exterior building, ride the elevator to the bottom, feed a Small Battery into the master power room, authorize The First Reserve, The Safe Divide, and The Last Remainder at their PECO 1.0 terminals, then take the elevator back up and scan the pyramid model in the upper room with your Replica Scanner.

What to load into your ship before you dock

The facility has two doors on the front of the building. The ground floor door only needs power. The upper floor door stays locked and tells you outright that you need access to every seed room first, so there is no shortcut past the tunnels.

Bring	Why
Wind Turbine or Solar Panel parts, plus cable	Permanent power for the exterior building, which runs the main doors and the elevator
Small Battery (at least one, ideally two)	Temporary power for the lower tunnels via the master power room
Weapon and a lot of ammo	Rollers patrol the corridors and corrupted growths block several doors
A light source	The lower levels are pitch black until the tunnels are powered; a head-worn lantern works well

Tip: bring spare junction boxes and extra cabling if you would rather run a permanent line down the elevator shaft instead of relying on a battery timer.

Power the facility in two stages

Eden Cradle runs on two separate circuits. The exterior building handles the front doors and the elevator. Everything below ground is on its own system, and nothing you build outside will light it up until you deal with the master power room.

Moor your ship at the dock outside the facility. A hostile spherical robot often hovers near the entrance, so clear it before you tie off.

Climb the stairs and go around the back to find the power building. Place a Wind Turbine or Solar Panel nearby, run cables inside, and plug into the main power outlet.

Flip the switch. The main doors and the elevator now have power, so head through the ground floor door and ride the elevator all the way to the bottom.

From the elevator, face the stairs going up and take a right, pulling the door open by its handle. Walk straight through the tunnel until you spot a black and orange barrel on your right, then turn right.

Cross the room with the two angels on the table and leave through the door on the back right. Follow that tunnel forward and take the first left to reach the master power room.

Insert a Small Battery to power the whole lower level. Lights, heal stations, and save points come online, and the powered doors between you and the terminals will finally open.

Note: a Small Battery does not last forever. If you move quickly you can clear all three authorizations on one charge, but running permanent cables down from your exterior setup removes the timer entirely.

The three PECO terminals and what they unlock

Each seed chamber is sealed behind its own authorization file, stored on a PECO 1.0 terminal somewhere else in the maze. You connect to the terminal, download the code, and the matching chamber door unlocks. The chambers can be done in any order, but the route below wastes the least walking.

Chamber	Terminal prompt
The First Reserve	Acquire the First Reserve Chamber Authorization
The Safe Divide	Acquire the Safe Divide Chamber Authorization
The Last Remainder	Acquire The Last Remainder Chamber Authorization

Tunnel routes to each seed chamber

The lower level is a loop of near-identical circular corridors, and it is very easy to walk in circles for twenty minutes. Use the barrels, the angel room, and the elevator hall as landmarks — they are the only reliable reference points down there.

The First Reserve

Walk straight out of the power room and take a left toward the closed door, which now opens because the level has power.

At the powered door at the end of that path, go right and then take the first left to reach another powered door. Go through it, follow the tunnel to the end, and open the door into the PECO terminal room. Download the First Reserve authorization.

Head back out through the powered door, take a right and another right, and pass through the opposite powered door.

Follow the tunnel to a handle door, then go left or right through the looped room — both sides connect. Two Rollers patrol here, so have a weapon ready.

As soon as you clear the second door out of the loop, turn left and walk straight ahead into The First Reserve.

The Safe Divide

Leave The First Reserve and turn left. Open the powered door, cross the bridge, and go through the handle door on the far side.

Keep following the tunnel until you can turn left, then pass through the handle door into the elevator room.

Go up the stairs and take the left tunnel. It is long and leads nowhere except the terminal, so you cannot get lost. Download the Safe Divide authorization.

Backtrack the entire tunnel to the elevator room, go down the stairs, then down a second staircase on your right and into the tunnel beneath the ascending stairs.

Walk straight ahead into The Safe Divide. A Roller usually sits in the corridor on the way in.

The Last Remainder

Exit The Safe Divide and take the left branch at the split.

Go through the handle door, immediately climb the staircase on the left, then move to the right side and through another handle door.

Turn left, walk to the end of the hall, and open the powered door into the final terminal room. Download The Last Remainder authorization.

Leave the terminal room, take the first left, follow the tunnel, and take another left. The red-lit seed room is directly ahead.

Step inside and listen to the voice prompt. That line confirms all three chambers are registered and that the Project Eden room on the upper level is now open.

Collecting the human seeds

Each chamber holds rows of seed pods, and the human seeds inside can be carried out. They are bulky, so expect several trips back to the elevator platform if you want all three. Hauling them is not what closes the quest, but the elevator platform is the sensible staging point if you plan to move them up to the surface afterward.

Robotic enemies you destroy along the way can be dismantled where they fall, which is worth doing on the return trips since you are already walking the same corridors.

Finish the quest by scanning the Project Eden model

From The Last Remainder, walk down the hall and take the first left. Cross the room with the angels on the table, then take the first room and open the handle door to get back to the elevator.

Ride the elevator up to the main deck, walk up the exterior stairs, and enter the upper room that was locked when you arrived.

Equip your Replica Scanner and scan the large pyramidal model in the center of the room. Closing dialogue plays and the quest is marked complete in your tracker.

Why the run stalls

The upper door refuses to open. All three chambers must be entered and registered first; downloading an authorization is not enough on its own.
Doors in the tunnels will not budge. The lower level lost power, which means the Small Battery in the master power room has drained.
The ground floor door and elevator are dead. The exterior power building has not been wired up or its switch was never flipped.
You cannot find a route. Corrupted growths seal several passages and need to be shot out before the door behind them will open.

Wrapping up here rolls straight into First Roots, which sends you to Eden Platform Pishon, northeast of the Last Listener Station, to build the Eden Frame and plant your first tree. Stock up on Stainless Steel before you sail — the frame alone eats 50 of it.
