Dual Universe is a massively multiplayer online game built around a continuous single-shard universe—meaning everyone plays in the same massive world with no loading zones or instancing. Using advanced voxel technology, players can build anything from ships to entire cities, and all structures persist in the same world. Its real-time ship-building, market economy, and Lua scripting capabilities allow for programmable gameplay mechanics, making it a sandbox for players who love engineering, coding, or economic strategy.
