Uranium is one of the rarest materials in the game. It can be used to craft very powerful but slow blunt weapons (with the uranium mace being the most powerful blunt melee weapon in the game), and it is also a required element in the construction of certain late-game high-tech constructions, most notably the end-game ship.


Tiles of uranium ore can be found rarely throughout the map, but must be mined before they can be used. Small amounts of it can be salvaged from deconstructing ancient cryptosleep caskets, or may randomly arrive in cargo pods. The most reliable method for acquiring it is to purchase it from bulk goods traders. Once you've completed the research necessary to construct a deep drill, it can also be found in small deposits underground.

Playing in Large or Ludeonicrous maps (of 300x300 or 400x400 tiles respectively) offer greater chance of finding it on the surface.


Uranium ore in game

Uranium ore tiles have 4,000 health, making them one of the slower ores to mine. They can be found in veins ranging from 6 to 12 tiles in size. Each mined block yields 40 uranium, although miners with less than 8 skill in mining will produce less.

Version history

In Beta 18 or earlier, uranium is a small volume material.
