If you find the vanilla circuits too easy, you may like this mod. It will make all circuits in the game more challenging. You will need to build them from scratch...boards...components (resistors, capacitors, diodes...) and put it together to have your circuits. This mod will override all three circuits levels, will add a forth to unlock futurist techs such the high-speed/high cargo robots and the quantum computer.

As you evolve in the mod, you may need advanced electronics parts. Such advanced technology demands rare materials, high-tech parts and research.

More than 15 new buildings and 100+ recipes that will increase the difficulty of your game, specially on the electronics part and also rebuilds the entire production of hightech science pack.

Not compatible with Bobs. The use with Bobs or Angels mods may cause bugs or incompatibilities.
This mod will only run with pY Coal processing mod and pY Fusion Energy mod installed as all mods in that suite.
