Build with milliblock precision in Fractoid, a multiplayer voxel sandbox designed for creative freedom. Create incredibly detailed structures, collaborate with friends, and help shape the game as it grows through Early Access, with survival mode planned for the future.
Fractoid
SteamFractoid is a voxel sandbox built for precision creativity.
Instead of placing large blocks like traditional voxel games, every block in Fractoid can be divided into milliblocks — allowing extremely detailed builds in 3D space.
Create intricate structures, detailed architecture, sculptures, or entire worlds using a powerful and flexible building system designed for creative freedom.
Build alone or create together with friends in multiplayer, collaborating on detailed projects in a shared voxel world.
Whether you want to build massive structures or focus on tiny details, Fractoid gives you the tools to push voxel building further than ever before.
Each block can be subdivided into hundreds of smaller pieces, allowing builders to create shapes and details impossible in traditional block games.
Build curved structures, custom windows, detailed trim, sculptures, or anything else you can imagine.
Build together with friends in multiplayer worlds.
Collaborate on massive projects, experiment with designs, or simply enjoy creating in a shared sandbox environment.
Fractoid currently focuses on pure creative building, giving players the freedom to experiment with shapes, materials, and structures.
Perfect for players who enjoy designing, experimenting, and pushing the limits of voxel construction.
Fractoid includes tools designed to make detailed building intuitive and fast:
• Milliblock precision building • Slopes and angled blocks • Fast placement tools • Flexible material system • Smooth building workflow • Copy, paste ability
Fractoid is currently in Early Access and actively evolving. Player feedback will help shape the future of the game as new systems and features are added.
Fractoid will continue expanding over time. Survival gameplay and additional systems are planned for the future, bringing new ways to explore and build within the world.
