PrimeCraft

PrimeCraft is a sci-fi sandbox about exploring a vast, procedurally generated universe of miniature planets, training AI companions, and jumping into handcrafted scenes created by the community. Every world you visit has its own gravity, terrain, and strange little challenges, and you’re free to roam, experiment, or simply relax and explore. Travel between billions of unique planets, drop into “bubble” scenes for small self-contained experiences, and return seamlessly to open-world exploration. Play solo or bring friends along in multiplayer and local split-screen modes. Your AI companion learns directly from your actions. Teach it how to move, navigate worlds, help you, or take your place entirely inside any scene. AI behaviour persists across worlds and sessions, creating a growing sense of personality as you explore. PrimeCraft is built around playfulness, physics, and discovery. Whether you’re drifting between planets, testing a new AI reflex, or showing friends a strange world you found, the universe is designed to surprise you.
