Developer Explains How Catalysts Work in Big Pharma
The developer of Big Pharma has released an update about how catalysts will work in the game.
Essentially a catalyst is a property of an ingredient, that is sometimes required to upgrade an effect to next level or remove some side-effects from the ingredient.
There will be five types of catalysts, each indicated by a different symbol. If an ingredient does not have a property with a catalyst, it needs to be added to it via a machine from another ingredient to be used to upgrade or remove effects.
