Terra's Atomic Disassembly is a pack for the Terra community. The pack is galacticraft based but there's quite a bit of mods like tinkers construct and immersive vehicles. The modpack can be played in singleplayer or in singleplayer. The choice is yours!

Mod Descriptions

Galacticraft:

Galacticraft is the main mod we have in this modpack. With Galacticraft, you are able to create rockets and rovers to travel to other planets. Each planet has unique terrain features and dungeons that contain bosses and blueprints for better rockets. The server has a discord where you can follow the space race that is happening between the factions.
