About this Mod
As of the 1st of June 2025, all future updates for ampz mods will require Voltaic API, and not Electrodynamics, in order to function. This update affects all the mods and brings world breaking changes, which are written in the changelogs. Note that this should however not corrupt your world. If you have such issues reach out on our discord channel!
Assembly Lines intends to increase the efficiency of factories or production lines. It makes the game more realistic by providing useful machines that facilitate the transfer and storage of items. It is based upon the old Voltz mod and therefore follows the same base systems.
This project is based upon Voltaic and requires this mod to run.
