Lunar Mass
Deploy bots to build a lunar mass driver while carving new craters in the Moon.
About Lunar Mass
Lunar Mass is a 3D building sim set on the Moon. The player constructs a mass driver, a huge launch structure, by putting an arsenal of bots to work on the surface. Progress comes from managing those bots and pushing the megastructure toward completion.
Construction leaves a mark on the terrain, since new lunar craters appear while the work goes on. The mix of adventure, strategy, and simulation gives the build a planning side as well as a hands-on one.
It was submitted to Vibe Jam 2026 and runs on Three.js. The creator built it with Cursor. They describe it as a way to learn about the Lunar Mass Driver project with the Terafab team, and they plan to grow it into a more realistic simulation later.
