Aftershock is a small mod aimed at helping modpack creators develop a rich world in the post apocalypse. Giving players access to a bunch of random scrap components such as Circuits, Plastic Amalgams or Machine Parts that can then be used to make more useful things, or can be used to barter with others. How they are used is up to the modpack developer!
This mod provides structures that give loot exclusive to this mod, they are generally common, but not super common to make the world appear as if there was a world before whatever the apocalypse is. This mod does not do too much on it's own & just provides items & structures to better shape you're ideal apocalypse world.
This mod pairs well with my other mod, Blocks You Need!

And this mod was made with Worldly Galaxies IV in mind, which is why there is an WG-IV version
