RadioIsotopes
Play around with uranium tools, a nuclear fission reactor, nukes (including a nuclear rifle), etc...but beware of radiation (you should take precautions)!
On your way to the use of the powerful atomic forces you might find old laboratories and nice villagers who will help you.
Contents
Currently Implemented Resources:
Uranium
Lead
Lithium
Bismuth
and much more Items and Blocks derived from them.
Spoilers (e.g. expand if you need help)You'll find the uranium centrifuge (which is also the working block for the physicist) in a structure somewhere in the end
You can buy uranium centrifuges and plutonium reprocessing plants from the physicist
When you have problems with radiation, you can make yourself lead armor or protect yourself with lead blocks or industrial casing
=> Recommended when you build a reactor (it can explode...)
- Ores: Lithium ore only generates inside diorite; Uranium ore mostly generates inside deepslate; Lead ore and bismuth ore mostly generates inside stone
Shhh... When you are tired of mining uranium all day long, try the living and also green looking alternative
