Viscosia Asteroid guide: the oil moonlet no cluster places
AsteroidsHard
What the Viscosia world file generates in the current game, and why many seeds fail, with two in-game examples.
The Viscosia Asteroid is a 64 × 96 cell moonlet of oil fields and rust over a magma core. The game describes it as filled with crude oil, natural gas and ethanol. In the current game the oil is modest: 27 to 29 tonnes of Crude Oil and 25 to 52 tonnes of Ethanol on the two sample worlds.
The world file guarantees one of eight oil-pocket templates. On three of the five seeds tried (1234567, 2468024 and 31415926) none of them fit, and the game stops world generation with an error. Seeds 55555 and 909090 generated.
No cluster in the current game places this asteroid, so typing a seed never produces it. Players meet it in custom clusters built with cluster-editing mods such as Cluster Generation Manager. The screenshots below come from the game's own world generator: a Terrania Cluster game in which the Superconductive Asteroid placement was replaced by this world file, so the cluster coordinate under each picture does not reproduce the asteroid in an unmodded game.
| Fact | Value |
|---|---|
| Size | 64 × 96 cells |
| Where you find it | No stock cluster; custom clusters only. |
| Biomes | Oil field at the surface and an oil patch below, a rust biome and a small magma core. |
| Guaranteed | One oil-pocket template; generation fails when none fits. |
| Peak light and radiation | 80,000 lux of sunlight and 250 rads of cosmic radiation at the surface. |
Strengths
Weaknesses
- No geysers on either sample world.
- No water at all.
- Magma close under the surface: 770 to 1,230 tonnes.
What to target first after landing
- Land on the surface and build a small sealed outpost.
- Capture Slicksters if the colony ranches them.
- Pump the crude oil and ethanol before mining around the magma.
- Mine the lead and the diamond.
Surviving the asteroid
The asteroid is small and dry. Bring water and oxygen, and keep visits short.
Example 1: world seed from SNDST-C-55555
16 Slicksters and 419 tonnes of lead; no geysers.

Example 2: world seed from SNDST-C-909090
10 Slicksters, 52 tonnes of ethanol and 1,230 tonnes of magma; three Sporechids bring zombie spores, so dig around them.

Role in the colony
In a custom cluster, Viscosia is a small lead, oil and Slickster stop rather than the oil world its description suggests.
