How do I extract? It keeps sending me back in.

Use the extraction markers (green boxes) and trains. Leaving a breach is only possible by train.

  1. Find an extraction marker: a green box.
  2. Check where its train goes before boarding: destinations differ, and some lead into other breach regions.
  3. To get home, take the marker for your hub, for example ZHAT for Zhat Kali.
  4. Check your build rating: a train into a breach region refuses ships above that tier's maximum, with cargo counting at 25%. Over? Take a different train.
  5. Fly to the marker and harpoon onto the train.

Warning

If your harpoon disconnects in the tunnel, you're left behind and must fly back to reconnect. If the next train arrives while you're still in there, it runs you over.

Tip

Nothing you carry counts until you have extracted. Extracting from a tier is also what clears it and opens the next one.

  • Discord: trusted player, 4 Oct 2026: the marker to head for is the green square for your destination
  • Discord: developer answer, 3 Oct 2026: a harpoon that disconnects in the tunnel leaves you there; fly back to reconnect
