The Strata

Topsoil0 – 200m
air: free
Iron everywhere near the surface, copper from 72m. Soft digging, gentle falls. Earn your first upgrades here.
Shallow Rock200 – 600m
gas pockets from 276m
Iron thins out by 264m; copper is the workhorse, silver appears from 360m. Harder rock digs slower — a better drill pays for itself.
Deep Rock600 – 1,200m
hot · lava from 708m
Gold from 660m, platinum from 1,020m. Dark — your headlamp is all you get. Long flights home; watch the fuel gauge.
Magma Margin1,200m +
open lava
Platinum country, and the only home of Descentium ★ (from 1,380m). Lava pools glow through the dark — that's the warning and the beacon.

Each ore is rarest at the edges of its range and richest in the middle. Descentium is guidance ore — the trader won't take it, the rocket needs 3. It still occupies cargo space, so plan the haul home.

What's Trying To Stop You

Gas pockets Dirt with faint green speckles, 276m and below. Drilling one detonates it — deeper pockets hit harder (up to 45 hull).
🔥
Lava From 708m, pooling wider with depth. Touching it burns 40 hull/sec and slows you. It glows through the dark — heed the glow.
Falling Drops of ~5 tiles and more damage the hull, scaling with speed. Feather the thruster on the way down — or buy the parachute and never worry again.
Running dry Empty tank strands the pod: surface tow costs 25% of your cash and all cargo. Hull failure costs 30% and the cargo. Turn back at half a tank — the screen bleeds red when it's getting serious.
Dying broke Stranded with less than $150 in the bank? Nobody tows for free. The pod goes dark, the run is over, the save is gone.
