Galacticraft-Legacy
Galacticraft-Legacy takes players off the planet, with spaceships, planets and moons to reach across the solar system on Forge for 1.12.2.
What it does
The mod lets players build a spaceship, customize it and fly between the planets and moons of the solar system. Exploring new worlds brings its own items and blocks, and the mod adds an electrical system and an oxygen system that a settlement on another body depends on. Players can form teams with flags and stats in space races, and the mod supports multiplayer, so a group can explore together on a shared server. Its translations cover several languages.
Galacticraft-Legacy is open source under the MIT License and was first published on 2021-02-24, with its latest Forge file, 4.0.6 for 1.12.2, dated 2023-12-09. Source code and an issue tracker are public. Both sides run the mod, so the server and every player need it. Fifteen other catalog mods require it as a base, including More Planets, AsmodeusCore [Galacticraft Addons Library], Galactic Research, Interstellar: Exoplanets and Space Ambient [Addon for Galacticraft].
