"An extremely hard, dense metal. While it is best known for its use powering nuclear reactors, its physical properties also make it excellent in some roles as a tool, weapon, or armor."
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 base game), and it is also a required element in the construction of certain late-game high-tech constructions, most notably the end-game ship. While one of the strongest building materials available, it has a significantly lower beauty modifier which can negatively affect some room designs.
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 tiles have 4,000 health, making them one of the slower ores to mine. They can be found in midsize veins, ranging from 6 to 12 tiles in size. Each mined block has a base yield of 40 uranium, however this is modified by factors such as the Difficulty setting and the mining yield of the pawn.
Uranium's high hit point multiplier make it a useful material for walls. A wall created from Uranium has 750 hit points which makes it the second strongest constructed wall, stronger than any of the stone blocks and only beaten out by plasteel. This role was more important while plasteel was still flammable, as uranium was the strongest non-flammable wall, but even now it still has merit when an excess of uranium or dearth of plasteel is experienced.
Uranium is also the best material for crafting stuffable blunt weapons such as clubs and maces, as it applies the highest multiplier on melee blunt damage of any material, tied only with Jade (which can only be used with clubs), and only causes a moderate increase in attack cooldown times. A high quality uranium mace is a respectable weapon at any stage of the game.
