World · How it works
Explore
Caves on five levels, giant lodes marked by ore boulders, geodes, oil under bitumen, raisonite deep down.
In the game
How to get it
Find a cave entrance (a hillside opening or a sinkhole) or dig down. Ore boulders on the ground mark a giant lode below; a bitumen puddle marks oil; geodes and raisonite hide deeper.
What it is for
Every ore of the game is underground: coal and iron near the surface, gold, titanium and gems deep down.
Why it exists
The world is as deep as it is wide: the best things are found by those who look.
The same text the game shows in its progress tree and on the item's sheet (I).
The underground of Openworld is a world of its own.
Caves
- Galleries on five connected levels, twisting tunnels, caverns held up by pillars, ravines, flooded halls and lava deep down.
- Entrances are rare: look for openings in hillsides and for sinkholes, or dig your own way.
- Without a torch a cave is pitch black: bring torches -- they also keep monsters from appearing around you.
- Monsters come to the noise of breaking blocks: see Monsters of the night.
What lies where
| Depth | What you find |
|---|---|
| 2 to 48 m | small veins in every cave: coal, iron, copper, a little bauxite |
| 3 to 70 m | coal veins |
| 10 to 140 m | iron veins |
| 20 to 160 m | Geodes: crystal, quartz and gems |
| 35 to 110 m | raisonite pockets (an iron pickaxe or better) |
| 70 to 200 m | gold; titanium from 90 m, gems from 100 m |
See Ores of the Earth for every ore.
Giant lodes
Huge deposits, 40 to 120 m wide, with a core of pure ore. Coal, iron, copper and bauxite lodes lie 250 to 700 m from the world's start; gold, titanium, gem, lithium, saltpetre, oil and uranium lodes within 1.5 km; dozens more across the planet. Ore boulders of 2 to 4 m on the ground above mark them from afar.
Oil
A bitumen puddle on the ground means oil below: dig down along the black conduit to the oil lens. Bitumen lit with a torch burns for good. See Crude oil.
