By the end, you'll be able to navigate this obstacle with confidence.
Understanding the Puzzle Setup
After the intense jeep chase and a precarious climb, you and Sam arrive at a large, flooded chamber. In the center are two enormous metal spheres—the Atlaspheres—resting in tracks. Your goal is simple: get to the elevated platform on the far side of the room. The means to do so, however, require some clever thinking.
The core mechanic involves using the two Atlaspheres to bridge gaps and create pathways. The key things to understand are:
- The Spheres are on Tracks: Each sphere moves along a predetermined, U-shaped track. They cannot be moved freely around the room.
- They are Your Platforms: The primary function of the spheres is to act as movable platforms that you can climb on and use to reach higher areas.
- Water is Your Friend: The flooded floor allows you to swim between the different sections of the chamber. You'll be diving frequently to get from one track to the other.
With this basic understanding, let's dive into the step-by-step solution for the Atlasphere room.
The Complete Step-by-Step Atlasphere Puzzle Solution
Step 1: The First Sphere and the Initial Climb
- From the starting point, dive into the water and swim straight ahead. You'll surface in a small area with the first Atlasphere.
- Push the first Atlasphere along its track until it reaches the end. It will settle against a platform with a climbable wall.
- Climb onto the sphere and then jump to the ledge. Follow the linear path until you drop down into a new section with a winch mechanism. This is the control for the second Atlasphere.
Step 2: Lowering the Second Sphere
- Interact with the winch. You'll see a cutscene where the second, larger Atlasphere is lowered into its track in the central chamber.
- After the cutscene, turn around and jump into the water below. You'll now be back in the main room, but with access to the second sphere.
Step 3: Positioning the Second Sphere for the First Bridge
This is where the puzzle logic in Uncharted 4's Atlasphere chamber becomes clear. You need to use the second sphere to create a bridge.
- Swim over to the second Atlasphere (it's the one now accessible in the central part of the room).
- Push this sphere along its track all the way to the end. It will stop just short of creating a bridge to a platform with a large wheel mechanism.
- This is your first "Aha!" moment. The sphere is just a little too low to jump to the platform. You need to raise the water level.
Step 4: Raising the Water Level
- To raise the water, you need to open a floodgate. Dive into the water near the second sphere and look for a tunnel. Swim through it, and you'll emerge in a small chamber with a rusty crank wheel.
- Turn the wheel. This will open the floodgate, and the water level in the entire room will rise significantly.
- Now, swim back to the second Atlasphere. Because the water level is higher, the sphere is now floating, raising its height. This is the crucial trick for solving the Atlasphere water level puzzle.
Step 5: Creating the First Bridge and Reaching the Wheel
- With the water raised, push the second Atlasphere back along its track to the same end position as before.
- Now, because the sphere is floating higher, it will perfectly align with the platform. Climb onto the sphere and jump across to the platform with the large wheel.
- Interact with the large wheel. This will shift the tracks in the room, changing the possible paths for the spheres. This is a vital step that many players miss, so if you're stuck, double-check that you've turned this wheel.
Step 6: The Final Sequence with Both Spheres
Now for the home stretch. This part involves a clever dance between the two spheres.
- After turning the big wheel, dive back into the water and return to the first Atlasphere (the one you started with).
- Push the first sphere along its track. Because you shifted the tracks, it will now move into a new position in the center of the room, directly beneath a hanging platform.
- Climb onto this first sphere. From here, you can now jump to and climb the hanging platform. This gives you a high vantage point.
- Look towards the second Atlasphere. You need to get it to the other side. Jump from your high platform onto the second sphere.
- Now, push the second sphere along its track in the opposite direction from before. You will push it all the way to the far end, where it will create a bridge to the final exit platform.
- Simply walk across the sphere to the ledge, and congratulations! You have successfully navigated the Atlasphere puzzle in Chapter 12 and can continue your adventure.
Common Troubleshooting and Pro Tips
- "The sphere won't go where I want!" Remember, the spheres are on fixed tracks. You can't steer them. If you're stuck, re-examine the room from a high point. The solution almost always involves moving a sphere to the end of its track.
- "I turned the wheel, but nothing changed." The large wheel on the platform doesn't move something obvious nearby. It reconfigures the tracks for the first Atlasphere, which is in a different part of the room. Always go back and check the first sphere after turning this wheel.
- Use Your Perspective. Don't be afraid to climb to high ledges to get a better view of the room layout. This is a classic Uncharted 4 environmental puzzle, and the solution is often revealed by understanding the space.
- Listen to Sam. While Sam won't outright solve the puzzle for you, he often provides subtle hints about what to do next if you linger for too long. His dialogue is part of the game's clever in-game guidance system.
