Science Difficulty Overhaul
Have you ever wished for a mod that would make manufacturing science packs more complex and challenging, without straying too far from the spirit of the game?
In that case, this overhaul is for you!
Science Difficulty Overhaul changes the recipe for all basic science packs and adds an extra one. The cost increases slightly, but it is in terms of complexity and production chains that the change is most noticeable. It consists of three customizable and complementary mods.
They're designed to work together, but can be played separately if you wish.
-
Harder Science Packs, which tweaks the majority of science pack recipes.

Better Space Science, which adds a bit of depth to space science.

Military MK2 Science Pack:
This mod add a new science pack used for some advanced military techs, as well as infinite military techs, and offers settings to customise the gaming experience as it fit to you.
It’s in the same price range as production/utility packs and add some complexities in the production chain. The ingredients needed in the base pack are reused in the MK2 pack, with the exception of walls. However, the MK2 packs still include 10 stones per pack in the form of concrete.

For maths lovers:
This is the cost for ONE science pack, without any productivity bonuses at any stage in the production chain:
- 36,83 Iron
- 15 Copper
- 5,5 Steel
- 11,67 Coal
- 10 Stone
- 2 Plastic
- 0,83 Explosives
- 50 Crude oil
Most changes can be customised in the settings !
No fewer than 15 customisation options:

Available in the following languages:
- English
- Français
