Stone

Stone is one of the several natural blocks which you can utilise for your construction projects.

Usage
The stone block is a cheaper alternative to metal blocks. As they both weigh the same, the advantage of using stone blocks is a lower cost (3 materials vs 5) and it is immune to EMP. Therefore it is most commonly used as EMP protection for blocks such as AI, being a cheap alternative to Surge Protectors and Heavy Armour.
