Giant's Deep - Outer Wilds Guide - IGN (2025)

Giant's Deep is a planet swirling with tornadoes that shoot elements of the surface into space before gravity crashes back down to the surface. This page contains all the locations and secrets of the planet.

You have probably been wondering how you're continuously waking up in the same moment every time you die by your own hand or an as of yet unexplained supernova. That question at least, is about to be answered.

While hovering over Giant's Deep you'll see an island with a black hole teleporter on it (the giant orange glowing swirly S shape). Land in the blue beam here with your ship.

As you get out and make your way to the door, you'll find it busted from the outside. However, to your left is a gravity crystal path. Head there and use it to navigate yourself via a secret path into the building.

Heading through the buildings and out onto the large teleporter, you'll see a message greeting arriving Nomai, along with letting them know that the lab for this island lies beneath it.

With this knowledge we can now head beneath the surface of the water and up into the recessed cave of the island.

There, using the Nomai Translator on a nearby recording, we learn the secret of the statue that looked at us at the beginning of the game. It's a device used to record the memories of Nomai, and using the Ash Twin Project, can relay those memories both past and future to whatever being the statue is paired with, which is why you're able to remember everything that happens before you die, despite being in the past. This allowed the Nomai to fix any issues on the Ash Twin Project before testing it.

The Tower of Quantum Knowledge is a Nomai location that can be found on Giant's Deep that teaches players the first rule of Quantum Objects through a series of trials.

How to Access the Tower of Quantum Trials

The Tower can be found inside one of the swirling tornados found on the surface of Giant's Deep. Not just any tornado however, but the largest one on the planet's North Pole.

Head there and then simply use your thrusters to boost yourself up and over the wall of wind to come upon the Tower hidden inside.

Conquering the Trials

Once inside the tornado, land on the platform and head up the path to the left. Eventually you'll come to an transporter beam that will take you up and into the Tower.

Inside, you'll find a large room with a Nomai message stating that these lessons are for you to learn for yourself. You'll also see an archway with a hole beneath it. Head into the hole to begin your first trial.

Inside a Nomai text will tell you to seek the wandering arch. You may notice a corresponding arch within the room that moves every time you look away from it. This is a quantum object, and you must keep your camera fixed on it as you move towards it. Doing so will allow you to access the hole underneath and progress to the next Trial.

Falling through the hole, you'll come upon a similar object that moves when you don't look at it. It is a shard of the Quantum Moon, but there is no Trial associated with this floor, so head through the hole in this room to progress.

The Nomai writing within the next room you fall into lets you know that observing an image of a quantum object and observing the object itself are one and the same. So in being able to photograph with your Scout, you may be able to guess where the solution to this problem lies. Once again you're faced with a wandering arch, however this time walls will always block your view of it. To keep it in the same place, snag a photo of the arch with your Scout and keep in front of your field of view as you move up the stairs to the arch's location. In having the photo of it, it won't move, and you can progress to the next riddle, falling through the hole under the arch.

In the next room, a Nomai text informs you that the gravity crystal on one of the walls that allows you to climb one of the walls, and the arch that lies atop those walls do not meet naturally, and both objects are quantum and move around the room on their own.

To solve this puzzle, first take a photo of only the crystal on the wall, without looking at the top of the all. In doing so, the crystal will stay put and as you turn around, the arch will move around the room. Once the arch and crystal lie on the same location, photograph the whole platform, arch and crystal both, and then you'll be able to climb up and reach the arch, and head through to the next Trial.

Note: you can also solve this puzzle by taking a photo of the arch once both are located on the same wall, and then fire your Scout above the wall to view the arch in the photo. Finally, avoid diverting your view from the crystal as you climb the wall.

As you enter this final room, the Nomai writing informs you as much but also mentions that it's a harder challenge. On opposite walls of the room, each has two quantum gravity crystals whose positions change each time you look away. Using your Scout, fire at one of the walls with the crystals in the bottom and middle row of the wall, then climb up to the middle section.

Once there, take a picture of the middle crystal but NOT the one at the base, then spin until the crystal appears in the highest row above you. Look directly at it as you climb up the wall and over the edge to reach the top platform.

You may find once you reach the top that the arch is on the other side of the room. However, this is no problem for a master of the first rule of quantum objects.

Simply spin around until the arch appears on your side of the room, then drop through the hole beneath it.

In the final room of the tower, Nomai writing on the wall congratulates you on your achievement, and simultaneously let's you know that the other shards also have lessons to teach.

So to recap the first rule of quantum objects:

Objects don't move as long as you are looking at them, and looking at a picture of the object and the object itself are the same thing.

If you've taken the time to try and penetrate the deep water of Giant's Deep and come out the other side, you have probably found your attempts futile. However, there is a way to do so with a great secret hidden within.

How to Access Giant's Deep's Core

All across the surface of Giant's Deep you've seen the tornados that spin sending pieces of the planet shooting into space.

However, if you've explored the Observatory on Brittle Hollow, you may have seen that the Nomai discovered this upward movement only applies to tornadoes spinning clockwise. The more rare counterclockwise tornado will shoot objects down as easily as its counterpart shoots things up.

You may see where this is going now. Head into a counterclockwise tornado while in your ship, and you'll be sent deep below the surface of Giant's Deep's ocean.

However, here we're met with yet another conundrum. Looking down, you'll see a large electric core with red jellyfish floating above it. Trying to penetrate the core with only your ship again is a futile venture.

The knowledge of how to get in however, can be found on Dark Bramble. If you've encountered the Jellyfish Corpse there, you'll find that Feldspar went inside one of the jellyfish to travel into Giant's Deep's core. You may do the same! Approach a jellyfish from the base inside your ship, then rise upwards into the head, allowing your vision to be filled with the translucent red glow.

Once inside, the jellyfish will ferry you through the electric barrier, giving you access to the core of Giant's Deep and the secret area it holds.

Inside, you'll see a large purple core with sprouting vines coming out of it. Attached to these roots you should see a Nomai structure. You'll want to land on it somewhere and make your way inside. To get in you should see a tube on the side of the building similar to the one used to enter the White Hole Station. Inside you'll find a switch to open a door to let you into the Probe Tracking Module.

Probe Tracking Module

Once inside the probe tracking module you'll find a ceiling and floor both with gravity walls as floors that allow you to walk on the surface of each.

Let's head to the one with the large tube sculptural object first. Using your cursor, to drag the ball into the first two switches, you'll be given a visually spectacular representation of the launch of the Probe Tracking Module. You'll learn that between combining the Memory Statues and these probes, they fired 9401 Probes with the 9354th finding criteria matching the Eye. The 4th and final switch will create a projection of 3 symbols.

These are the exact coordinates of the Eye of the Universe, and you'll need them later to reach the Eye.

On the ceiling you can read two separate Nomai conversations about the Probe with expectations and hopes high about the chances of receiving the Eye of the Universe coordinates.
