About this project
What does Exolith add?
Exolith is a tech-magic mod focused on unmanned space exploration, crystalline energy, and automation.
Instead of generating laggy, empty space dimensions, Exolith lets you manage a space program from the comfort of your Overworld base. Design modular probes, track orbital trajectories through an interactive celestial telescope, harvest exotic matter from distant star systems, and power up your base and personal companion.
For player convenience, the mod includes an in-game guidebook (Exolith Codex) that provides detailed explanations of all its features.

The mod is in early beta, and a lot of new content is planned!
Exolith offers:
- A space exploration system using modular unmanned probes
- An in-game celestial telescope to discover planets and track flights in real time
- A wireless energy network based on crystal resonance and optical lenses
- A customizable companion that assists with mining, farming, and combat
- Factory logistics with conveyors, ore crushing, and automated launch pads
- Rescue missions to recover lost modules and cargo from crashed probes
- Exotic materials to craft base gravity controllers and machine accelerators
Getting Started:
- Locate a fallen meteorite in the world and craft the Astro-Journal.
- Grow crystals and set up resonance pedestals to generate energy.
- Build the telescope to scan the sky and find target planets.
- Assemble your first probe on the launch pad and send it on a mission.
