§1

The run, in five moves

Store description + player reports
  1. Ride the cursed elevator

    A run starts in the Outpost lift and drops the crew into shifting underground ruins. Players report the extraction quota is shown inside the elevator, so the target is set before the doors open.

  2. Break the furniture

    Furniture is the loot and the arsenal at once: smash it for resources, carry it out whole, or swing it. First-day reports describe chairs and planks used as improvised weapons.

  3. Feed the Grinder

    The Grinder turns hauled furniture into gold, and gold is what the Outpost is rebuilt with. That is the only reason to carry more than you can run with.

  4. Break, and keep playing

    A splintered vessel leaves you in the run as a bodiless Spark: you can guide the team through the dark, and you must force your way into a new host with a different ability set before you fade out.

  5. Extract, or lose the haul

    If every member of the crew breaks, the run loses its loot. Players report the carried items are gone and depth resets to 1, while player level and room levels survive.

The published description stops at the shape of the loop. Quota values, timers and depth scaling have never been released, so this sheet does not print them. The Descent carries the same loop with the HUD readouts attached, and Sparks & Vessels covers what happens the moment a vessel actually breaks.

Unresolved at filing

A launch-week ledger is only useful if the blank lines are marked as blank. These are the ones that matter, and none of them can be closed from a first-party source today.

What nobody has published

Enemy, boss and biome namesThe 1.0 scope list adds all three categories and names none of them
Stats, drop rates, upgrade costs, quota valuesNo numbers released
Maps of the Deep LayersProcedurally generated; no spatial data exists

Patch notesNo post-launch patch has shipped; the record ends on launch day

What is confirmed works through the same gap in full, including why competing wikis look larger while restating the same store description.
