Antimatter Chemistry is a questing/progression pack inspired by Anti-Material Energy (1.7.10) by Parcel31u. You find yourself stranded in the Antimatter dimension with nothing but some basic gear, a chemistry set, and the hopes of returning back to your home.
Coming in at about 100 mods, this pack loads quick and performs well on potato computers, but still remains a unique hand-crafted and engaging experience that can provided dozens of hours of fun that feel nothing like vanilla.
Alchemistry (My own mod, forms the foundation of the pack)

Avaritia (For those who care to use it in the end-game)
