Upgrades
One-off boosts for this run; a Collapse takes themEvery upgrade bought. Further multipliers come from shards, Aether and Ingots, and none of those is lost to a collapse.

Collapse
Reset the run for Shards; the shop keepsCollapse resets stardust, generators and regular upgrades. You keep Singularity Shards and every purchase made with them. Lifetime Shards permanently multiply all production.

Crucible
Patterns that survive a Collapse, paid in Ingots from the meltCollapsing converts owned generators into Ingots: each complete group of 25 contributes, and larger stacks pay more. Ingots buy Patterns; every level adds five starting generators to that tier after future Collapses. A Compress resets Patterns.

Castings
Castings are consumables queued for your next Collapse. They activate at the start of the new run, then leave the queue.
The Mandrel remembers your last Castings queue and repeats it in one press.
Vault
Aether, refined into permanent multipliers and HarmonicsAether survives a collapse and a challenge. Only a Compress takes it, with the rest of the layer. It stops flowing while you own no Galactic Nexus, and starts again the moment you own one.

Aether
Every refinement bought. Harmonics continue from here.
Harmonics
Harmonics multiply all production and survive Collapses. Each level costs more Aether, the line is soft-capped at the Harmonic cap, and it has no maximum.

Contracts
Standing work · paid in Salvage when it comes inWorkshop
Buildings paid in the materials expeditions bring backEvery building level is permanent and survives every reset. Each building costs a different mix of materials.
Compress
Reset the Collapse layer for Neutronium; caps, levels and DutyCompress resets the systems that survive a Collapse, including Shards and their shop, the Crucible, Vault, Workshop, crew, and challenge progress. It pays Neutronium, which survives future Compressions. Achievements and lifetime records remain.

No Compressions yet.
Kept by the Vise
Nothing to Compress yet. It takes what a Collapse keeps: shards, the Collapse shop, the Crucible, the Vault and the Workshop.
Kept, always: every achievement and every Laurel, every record, every lifetime total, your settings, and the Vise itself.
Breadth
0%Breadth is how much of the game you have played, across 12 systems. More breadth makes every cap and every Fracture level cheaper.
Caps
Each row raises one cap. Its price falls as you build breadth in the other systems.
Duty
A pool you spread across six multipliersAssign a limited Duty pool across stations to choose which systems receive a multiplier. Lifetime Neutronium adds capacity after each Compress. Changed plans must spin up before reaching full output.
At full duty.

Descent
Crew sent down the shaft for materials and BasaltEvery stratum the cage clears raises crew rank and opens another one, whether the descent pays or not. Hardpan and deeper can come up empty.
The cage is at the head, waiting.
0 strata cleared
Crew on the cage are not available to the bay.
Depth
Push it one stratum deeper than Auto-descent would risk.
Mill
Turns the Descent’s haul into Carbide and stockThe Mill converts Regolith and Chondrite into Sinter, Isotope and Filament into Sinter, and Sinter plus Basalt into Carbide. Every converter runs continuously, including while you are away.
Expand
Reset the Compress layer for ChartersAn Expansion takes the whole of Stellar Foundry — the run, the Collapse, the Vise and everything under it — and pays Charters. Worlds and Shelf keys are permanent; everything else on this shelf is the layer’s own rebuild, and is bought again each time.
Shop
Charters
Shelf
Three multipliers bought with your own outputPriced in seconds of your own best output, so a price never goes stale: four minutes means the same thing in hour six and on day thirty. Switch on saving for a row and a quarter of your income goes into a pot; the row is bought when the pot fills.
Worlds
Five pocket games, each paying ChartersEach world produces its own currency while closed, up to its reservoir limit. A full bar means that world has stopped earning until you visit it or increase its reservoir.
Achievements
Permanent records · each one claimed pays LaurelsEarned once, kept through every reset. Claim each one for Laurels, and every Laurel you hold lifts all production.
Claim an achievement for Laurels.
Every achievement claimed.
Challenges
A Collapse under one rule · clear the target for a permanent bonusGive up any time. Targets are fixed.
The Sky
Constellations lit with Embers from challenge recordsGoing deeper on a challenge than you ever have earns Embers; repeating old ground earns none. Spend them lighting stars on the chart, from the bottom of each figure up, and a finished figure pays out forever.
Lines
Repeatable levels of Refit and ScaffoldRepeatable levels with no maximum. Each level costs more than the last, soft-capped.
Expeditions
Crew you send out; the haul builds the WorkshopOne crew for every job. More surveyors on a trip make it faster, not bigger. Launch a destination once and the standing order keeps sending that crew back out. The clock keeps running whether you're watching or not.

Nothing runs until you switch it on. Every automation also has a switch on the panel it acts on — and every one of these also has a control on the panel it acts on, so you never have to come back here to flip one off.
