PlanetSmith is a procedurally generated voxel adventure game where you must survive on an alien world after crash-landing with no way to return home. You will explore massive hexagonal block planets with a variety of biomes, from polar regions to desert equators, as well as continents and island chains scattered across the deep oceans. To survive, you will need to craft tools, weapons, and shelters, avoid hostile robots patrolling the surface, and delve into underground dungeons in search of technological artifacts.
