Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction.

Obtaining

Resource acquisition

Limestone can be harvested by hand (default E) in trace amounts from resource deposits scattered across the world, or from inexhaustible resource nodes on which Miners can be constructed to extract automatically. Additonally, Lizard Doggos will ocassionally bring it when tamed.
