The Problem

I found the Neutrino Detector but I cannot reach the portal inside it. How do I get to Voussoir?

The Solution

Voussoir is the climbing dimension, and getting there is half the adventure. The portal is inside the Neutrino Detector, which is that lone building sitting in the water on the northeastern side of the Hydroplant Sector. Before you even think about swimming out there, you need a Diving Suit. The swim through the Hydroplant tunnels is disorienting, so drop navigation markers or memorize landmarks. Once inside Voussoir, the dimension is all about vertical traversal — climbing mechanics are the core gameplay. The collectibles are Neutrino Mappers, and there are two save spots you can use as outpost bases. You will also find Digital Gold, Transcendium, and renewable materials.

Step-by-Step

1. Craft the Diving Suit once you find the recipe.
2. Navigate to the northeastern side of the Hydroplant where the Neutrino Detector sits in the water.
3. Swim through flooded tunnels — use landmarks to avoid getting disoriented.
4. Enter the portal inside the Neutrino Detector to access Voussoir.
5. Voussoir features climbing mechanics and Neutrino Mappers as collectibles.
6. Build two save spots for outpost bases inside Voussoir.

Common Mistakes

• Attempting the Hydroplant swim without a Diving Suit and drowning halfway.
• Getting disoriented in the flooded tunnels and swimming in circles.
• Forgetting to bring save spot materials and having no checkpoint inside Voussoir.
