Vulcanus is a hot volcanic planet with mountainous volcanoes, rivers of lava, plains of ash, and sulfuric acid geysers.
It is home to demolishers, a large boss‐like enemy that defends its territory. There's no pollution on Vulcanus.

Biomes
Vulcanus has three distinct biomes.
- Ashlands are plateaus speckled with sparse vegetation and deposits of coal. They are home to leafless alien trees. They are relatively free of cliffs and lava, making them ideal for building.
- Lava basins are filled with winding lava rivers. Within them are deposits of tungsten ore
, which can only be mined using the big mining drill.
- Mountains are large volcanoes, covered in cliffs and with a large lava pool at their center. They are home to sulfuric acid geysers and calcite
.
Demolisher Territories
Native to Vulcanus are the giant centipede-like enemies known as "demolishers".
Demolishers have well-defined territories. On the map, these territories are outlined by an opaque, bright red line and the inside is marked by diagonal, translucent, red lines. Only one demolisher will spawn per territory, and the territories themselves do not overlap. However, they are tightly packed, as they follow a Voronoi-like pattern. At the start of the game, only Vulcanus' starting area is not inside a demolisher's territory.
When left alone, a demolisher will patrol the border of its territory. However, if players build inside of a demolisher's territory, it will soon make a beeline towards these buildings with the intent of destroying them. Building inside of a demolisher's territory is therefore extremely risky and dangerous.
The death of a demolisher is permanent, as they only spawn during world generation. Likewise, upon the death of a demolisher, its territory permanently becomes free for the player to use, as other demolishers will not try to expand their territories.
Access to basic resources
- Water can be obtained via Acid neutralisation and Steam condensation
- Stone is a byproduct of processing Lava into molten iron/copper
- Iron ore is not available, but Iron plate and Concrete may be obtained from Molten iron
- Copper ore is not available, but Copper plate may be obtained from Molten copper
- Coal can be mined from patches on the surface as normal
- Crude oil is not available, but Heavy oil can be obtained via Simple coal liquefaction
Space routes
Vulcanus is connected to 2 other planets: Nauvis and Gleba.

Key reasons to go to Vulcunus
• The planet unlocks Artillery, allowing you to automatically destroy nearby nests on Gleba and Nauvis. This is especially useful when evolution rates are so high that they create nests faster than you can fight them.
• Foundries and Big mining drills ensure that resource patches last for a long time.
• Power is essentially infinite since solar power is quadrupled and acid neutralization can support a ridiculous amount of steam turbines.
• An almost inexhaustible amount of resources allows you to farm quality or scale up and grow a megafactory.
Key reasons to not go to Vulcunus
• The planet uses a ridiculous amount of coal, making oil production hard to create. Coal liquefaction makes this process slightly more effeicent.
• It is the closest planet to the sun, making transportation to other planets hard.
• Space is very limited as foundations are only unlocked much later on.
