Prerequisites for Accessing Voussoir

The Voussoir dimension is entered through a portal inside the Neutrino Detector. Before attempting to reach this location, prepare the following:

  • Diving Suit: Required for the approach through flooded areas. The suit must be crafted before attempting the swim.
  • Navigation markers: The underwater route through the Hydroplant can be disorienting. Prepare landmarks or place markers to track your path.
  • Save spot materials: Bring enough resources to establish at least one checkpoint inside Voussoir. Falls and failed climbs are punishing without a nearby reset point.
  • Inventory space: Reserve capacity for Neutrino Mappers, Digital Gold, and Transcendium. Filling inventory before learning the return route creates unnecessary risk.

Locating the Neutrino Detector

The Neutrino Detector sits as a standalone building in the water on the northeastern side of the Hydroplant Sector. The approach requires swimming through flooded tunnels beneath the Hydroplant. This underwater section is the primary obstacle before reaching the portal.

Swim Route Workflow

  1. Enter the Hydroplant from a known access point. Identify the northeastern section of the facility before submerging.
  2. Navigate the flooded tunnels using your chosen markers. The underwater passages branch in multiple directions; maintain awareness of which tunnel leads toward the open water where the Neutrino Detector sits.
  3. Surface at the Neutrino Detector once you exit the tunnel system. The building is isolated in the water, so look for its structure as you emerge.
  4. Enter the building and locate the portal inside. Activate it to transition into Voussoir.

Recovery advice: If you become disoriented underwater, return to the last known landmark and reorient. Swimming in circles wastes oxygen and increases drowning risk. If oxygen runs low before reaching the detector, retreat to the previous safe area and try again with better route preparation.

Understanding Voussoir's Climbing Mechanics

Voussoir is a vertical dimension where climbing mechanics form the core gameplay. Unlike horizontal exploration zones, this portal world tests movement skill and route planning. The dimension features:

  • Vertical traversal: Most objectives require ascending or descending significant heights. Assume vertical distance is the primary challenge.
  • Neutrino Mappers: These are the headline collectibles within Voussoir. They serve as the primary reason for extended exploration.
  • Two save spots: The dimension contains two locations where you can establish outpost bases. Use these as route anchors.
  • Renewable materials: Digital Gold and Transcendium can be collected repeatedly, making follow-up runs worthwhile for resource gathering.

Climb Safety Decision Table

SituationRecommended ActionRationale
Unknown climb aheadMark current platform before proceedingEnsures you can find the return path
Inventory partially fullBank valuable items at nearest save spotProtects loot if the next climb fails
Multiple risky climbs in sequenceSplit into separate runsReduces cumulative fall risk
Return path unclearStop and establish a route markerPrevents getting stranded after collecting

Route Planning Strategy

Treat the first visit as reconnaissance rather than a full clear. This two-pass approach prevents the common mistake of attempting to loot, map, climb, and build simultaneously.

First Visit: Reconnaissance

  • Find the portal entry and learn the immediate climb area.
  • Identify where you would build an outpost.
  • Locate the two save spots.
  • Leave before inventory fills.

Second Visit: Collection

  • Establish an outpost at the chosen save spot.
  • Branch out for Neutrino Mappers and rare materials.
  • Return to the outpost to bank loot before attempting further climbs.
  • Use the established return path to exit safely.

Mini-Outpost Guidelines

A functional outpost inside Voussoir does not require a full base setup. Focus on:

  • One save point
  • One small storage container
  • Food and water backup
  • Clear visual indicator of the return direction

Place rare finds into the container before attempting the next climb. If the subsequent branch goes badly, the most valuable portion of the run remains protected near the route anchor.

Recovery and Failure Prevention

Voussoir punishes forward-only thinking. A climb that appears straightforward on the way up can become confusing when returning with a full inventory. Apply these recovery principles:

  • Before each risky climb, verify you know the way back down. If uncertain, mark the platform or return path first.
  • Use save spots as route anchors, not decorations. Build or claim one before branching far from the portal path. This breaks the dimension into short climbing loops instead of one fragile expedition.
  • Do not carry every climbing reward through every new branch. Bank Neutrino Mappers and high-tier materials first, then explore with a lighter bag.

Common Failure Points

  • Attempting the Hydroplant swim without a Diving Suit leads to drowning before reaching the detector.
  • Getting disoriented in flooded tunnels causes wasted oxygen and failed approaches.
  • Forgetting save spot materials leaves no checkpoint inside Voussoir, making falls catastrophic.
  • Treating the first visit as a full clear instead of a route-learning run increases the chance of losing valuable loot.
  • Filling inventory before learning the climb back to the exit creates unnecessary extraction risk.

Priority for Extraction

When inventory space is limited, prioritize items that unlock other decisions:

  1. Neutrino Mappers: The headline collectible and primary reason for exploration.
  2. Digital Gold: Useful for later crafting and routing decisions.
  3. Transcendium: Valuable for crafting, though renewable on follow-up runs.
  4. Renewable bulk materials: Leave these for subsequent visits when you have established safe routes.

This priority order ensures that each successful extraction returns the most valuable items first, while renewable resources can be collected on later runs with less risk.
