How to use the Reconstructor (free revive)

Reconstructor rooms give you a free in-run revive. Here is how to spot and use them.

How to use the Reconstructor

Reconstructor rooms are basically free revives within a run — separate from Astronaut Figurines. Most players never use them because the prompt is missable.

What they look like

  • A small chamber with a glowing orange chair in the middle.
  • The wall has a distinctive Atropian totem pattern behind the chair.
  • They appear once per biome, usually past the midpoint.

How to activate

  1. Walk up to the chair.
  2. Press triangle to scan in. Costs 6 Ether (the green resource).
  3. The chair stores your current state.
  4. If you die anywhere in the rest of the biome, you respawn in the Reconstructor with full health.

When to use it

  • Always activate it on the way to a biome boss. Scanning in costs almost nothing relative to the value of a free revive at the boss door.
  • Skip if you're under 6 Ether and about to clear the boss anyway.

Common mistake

  • The chair only works for the current biome. Going to the next biome resets it. Use it before, not after, hard fights.

If stuck: if you can't find the room in a biome, it's behind a side door — Reconstructors are never on the main path.
