Exotic Matter

Exotic Matter is a single-player, open-world voxel adventure set on the randomly generated planet Xcylin. Shipwrecked there, you must find a rare substance that could save humanity from destruction. You explore the planet and the ruins of an alien civilization, uncover a sci-fi mystery through your own exploration, and expand your arsenal and abilities.

Explore Xcylin

The planet is fully simulated and open to exploration. You can mine resources beneath the surface, search for hidden treasures and secret underground complexes, and explore roguelike facilities generated so that no two dungeons or playthroughs are the same. Procedural generation shapes both the alien landscape and its facilities, creating different adventures each time.

Build and craft

Terrain is fully destructible and reconstructible. You can build shelters and bases using in-game technology, connecting lights and doors to switches, pressure-sensitive blocks and computer systems. The world includes many block types with different attributes and abilities, along with tens of ancient items and technologies left by the alien civilization.

Crafting combines personal crafting with large-scale crafting through replicator technology, allowing you to make more complex items. The game also includes countless items, weapons and block types to discover and unlock.

Generated facilities

You can explore tens of roguelike facilities, from large, important sites to small, secret ones. A sophisticated dungeon-generation system creates these facilities, while the planet's other procedural systems shape each adventure.

Create custom worlds

The moddable engine lets you explore community-created worlds or make your own sci-fi adventure. Built-in modding support opens nearly every aspect of the game to customization, including items, block types, planet composition, terrain and biomes.
