Summary

Adds a darker version of the vanilla science packs, such that you need to research both the vanilla pack and dark pack to fulfill a research. Makes the game more challenging. If a science has surface conditions, those are inherited. This goes through the entire tech tree - modded research is changed accordingly.

Double the science. Space Age compatible. For example - all research that uses automation science pack will now also use dark automation science pack. Dark science recipes are rather tame. Think of this mod as a way to ease into hardcore Factorio.
