Voussoir dimension: Neutrino Detector access and climbing mechanics

Field Complaint

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

Validated Response

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 — find the recipe and craft it, because deep diving without one is a quick way to drown in a confusing flooded tunnel. The swim through the Hydroplant tunnels is disorienting, so drop navigation markers or memorize landmarks before you commit. Once inside Voussoir, the dimension is all about vertical traversal — climbing mechanics are the core gameplay here, and you will be scaling surfaces the entire time. The collectibles are Neutrino Mappers, and there are two save spots you can use as outpost bases if you want to set up a temporary operation inside the dimension. You will also find Digital Gold, Transcendium, and renewable materials scattered throughout the climbing routes. Pro tip: there is another Neutrino Mapper in the Exor Village portal world, near the campsite where you find a dead scientist floating in the water — grab both if you are a completionist. Prepare your swimming gear, stock up on air, and mark your path before attempting the Hydroplant traversal. Getting lost underwater with no air is how runs end in embarrassment.

Summary

Voussoir requires the Diving Suit and a confusing swim through the Hydroplant. The climbing dimension inside is worth the trip.

Prerequisites

• Find and craft the Diving Suit recipe
• Navigate to the Neutrino Detector in the Hydroplant Sector
• Swim through flooded tunnels to reach the detector building

Recommended Loadout

• Diving Suit (required)
• Navigation markers for the flooded tunnels
• Climbing gear and two save spot materials for Voussoir outposts

Step-by-Step Route

1. Craft the Diving Suit once you find the recipe — you cannot reach the Neutrino Detector without it
2. Navigate to the northeastern side of the Hydroplant where the Neutrino Detector sits alone in the water
3. Swim through flooded tunnels connecting the Hydroplant to the detector — deep diving is disorienting, so use landmarks
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
7. Farm Digital Gold, Transcendium, and other renewable materials from the dimension

Common Mistakes

• Attempting the Hydroplant swim without a Diving Suit and drowning halfway
• Getting disoriented in the flooded tunnels and swimming in circles — place visual markers
• Forgetting to bring save spot materials and having no checkpoint inside Voussoir for the deep exploration
