Volcanic worlds have erupting volcanoes all over the surface, and plants with crowns glowing with the same colour as volcanic lava. Viewed from space, they look reddish. Temperatures are high just like on scorched worlds, sometimes ground self-ignites due to high temperatures. The resources are inconsistent.

Note that Hazard protection is always on due to high temperatures. Coolant Network upgrades are recommended, especially on extreme worlds.

Water can be found on some volcanic biomes.
