Outer Wilds guide: Giant’s Deep

Find Gabbro, the Memory Statues, the Construction Yard, and the Probe Tracking Module

Outer Wilds Giant’s Deep guide Mobius Digital/Annapurna Interactive via Polygon
Jeffrey Parkin (he/him) has been writing video game guides for Polygon for almost seven years. He has learned to love just about every genre of game that exists.

Two locations in Outer Wilds — the Southern Observatory on Brittle Hollow and the Orbital Probe Cannon — have pointed you to Giant’s Deep. Now, it’s time for a visit.

There’s quite a bit to do on the planet, but each location is relatively simple, so we’re going to combine everything in this guide. We’ll start with a visit to the resident Hearthian Gabbro, learn about the Nomai Memory Statues at the Statue Island and the workshop, find the Nomai Construction Yard, and finally reach the Probe Tracking Module that broke off of the Orbital Probe Cannon.

Find Gabbro

From orbit around Giant’s Deep, pull up your signal scanner. Listen for Gabbro’s flute to find where they are.

Drop through Giant’s Deep’s cloud cover, and fly along the ocean to Gabbro’s Island. You’ll find them hanging out in a hammock.

Talk to them to get all the information you can — this’ll add some information to your ship’s log. They’ll point you to your next goal: Statue Island.

The problem with the islands on Giant’s Deep is that the tornados keep tossing them around, so they’re never in the same place for long. Luckily, the planet is relatively small, so you can find them after just a couple minutes of searching. If and when you’re on an island that gets launched by a tornado, just ride it out until it falls back to the planet.

Statue Island

You’re looking for the island Gabbro described — two islands connected by a natural bridge.

Land on the gravity platform, and climb the stairs. All you have to do is jump the gaps, but gravity here is twice as strong as Timber Hearth, so jumping doesn’t work as well. Jump and jetpack boost your way across to the other side.

The door ahead of you is broken, so follow the path on your left, and use the gravity crystals to snake around to the very top of the cliff. Go into the building ahead of you, and drop down to read some Nomai script.

Exit through the other side of the building and follow the path up the hill (you’re crossing over top of the natural arch). There’s an inactive teleporter at the top with another Nomai note pointing you down to the workshop.

Head back to the arch and jump down into the water facing the broken workshop door you passed earlier. Underwater, you’ll see that the island is hollow. Head into the workshop from underneath.

When you surface, follow the path on your right around the room. Check the recording to learn about the Memory Statues and the Ash Twin Project. Continue up the stairs.

Grab the Ash Twin projection stone and use it in the two pedestals.

Drop back down, and open the workshop door to return to your ship.

Construction Yard

The final island to check out before we head below is the construction yard. Look for a small island with a landing pad and some Nomai construction sticking out of it (there’s also a tall, lone tree sticking out of the top).

When you land, head down the stairs nearby. Go straight and check the scroll laying nearby.

Use the gravity tiles on the left side to continue out into the ruins.

Pick up the Brittle Hollow projection stone, and use the ring of gravity tiles to loop over to the righthand side. Place it in both pedestals and read the script here.

Check the Nomai computer near the blank wall for information about the probe.

Grab the Launch Module projection stone and use it in both pedestals. You have already read most (all?) of this information, but this will reinforce it and guide you to your next location.

Ocean Depths

To get to the Ocean Depths of Giant’s Deep, the first step is to find the counterclockwise-rotating tornado. Just look for one of the smaller ones that’s spinning in the opposite direction than the others. Fly your ship inside, and it’ll launch you down. (If you end up in space, you’ll know you picked the wrong one.)

Under the water, approach one of the electrified jellyfish. Exit your ship and swim up to it (make sure you’ve got your suit on, obviously — we learned this from dumb, dumb experience).

Swim under the jellyfish, and then follow the tentacles up into its bell. You’re safe there from both the jellyfish and the core’s electrical field. Ride it out until a wave of electricity passes over you. Jetpack down and out of the jellyfish, and keep going down toward the core.

Probe Tracking Module

Once you’re inside the core at the coral forest, look around for the Probe Tracking Module. It looks just like the other two on the Orbital Probe Cannon. Enter through the tunnel and unlock the hatch.

Drop to the floor side — the side with the projection pool — and pick up the Ash Twin and Launch Module projection stones. Use them both in both pedestals to reinforce some more information — you’ve probably seen it all before, but it’s worth revisiting.

Outer Wilds Giant’s Deep Probe Tracking Module Eye of the Universe coordinates
Use the simulator in the Probe Tracking Module to learn about the probe(s) and get the coordinates of the Eye of the Universe.

Use the pad with three gravity crystals to switch to the ceiling. Use the ball and tube to check the simulator there. Read the Nomai computer output at each switch. The final simulation will give you the coordinates for the Eye of the Universe.

What have we learned? // What’s next?

We’ve learned a lot on Giant’s Deep. Now we (kind of) understand the Nomai Memory Statues — which also explain the time loop that you and Gabbro are experiencing — and their link to the Ash Twin Project. We’ve also learned that the Nomai probe(s) were successful in finding the Eye of the Universe and have its coordinates.

We’ve still got several rumors from back on Brittle Hollow that point to the Hourglass Twins (the Ember Twin and the Ash Twin) — Escape Pod 2, a quantum shard, the Fossil Fish Cave (and the anglerfish fossil inside), and the High Energy Lab.

But before we go there, there’s one more thing to do on Giant’s Deep. Inside that huge tornado that sits at the north pole, you’ll find the Tower of Quantum Trials. We’ve broken that out into its own guide.
