About this project
What does IC2 Extension add?
A relatively small mod focused on expanding Industrial Craft 2 without compromising overall difficulty & gameplay.
Requires Industrial Craft 2 v2.8.221-ex112
Generally inspired by mods like Compact Solar Arrays, GregTech and some other concepts found way back in 2012, some of which either become something completely different these days, or never made it in a long run.
Mostly meant for dedicated modpacks that uses minimalistic assets, and thus I do not plan on bloating it with octillion resources/machines or slapping 32x textures (unless SERIOUSLY required, otherwise use resourcepacks, or play with it as is). You are still welcome to use it any way you like.
