Space Engineers

Space Engineers is an open-world sandbox game about designing, building and testing space machines. You construct ships, stations and planetary bases, then explore planets and space, mine resources, survive hazards and fight alone or with others in Creative or Survival mode. The game uses block-by-block construction and volumetric physics: blocks and voxels have mass, inertia and damage, and ships, stations and terrain can be broken apart, drilled, carved and reshaped.

You can play solo or in multiplayer, from small co-op outposts to large community servers. Begin with a simple lander, build a mining and industrial operation, or focus on warships and planetary fortresses. The setting draws on real engineering, hard science fiction and plausible near-future technology, with ships, stations, tools and systems built and simulated block by block.

Build and engineer

You design and pilot small and large ships, asteroid stations and planetary bases. More than 200 functional blocks include thrusters, rotors, pistons, turrets, conveyors and production blocks. You can build in first or third person, use symmetry tools and blueprints for large-scale construction, and, in Survival, weld blocks together, grind them apart and reuse their components.

Shape a destructible world

The worlds contain voxel planets, moons and asteroids with atmospheres, gravity and climate zones. You can drill, cut or blast terrain to make tunnels, craters and underground bases. Ships and structures take damage block by block and can break into pieces; objects have mass, storage capacity and integrity, and can deform or be destroyed.

Choose how to play

Creative mode provides unlimited resources, instant building and no death. In Survival, you assemble things manually, manage resources and power, and can die and respawn. You can play alone or in co-op and competitive multiplayer, with privacy settings and dedicated servers. Scenarios, Workshop worlds and custom worlds let you choose the kind of universe to start in.

Explore and create

Super-large worlds contain procedural asteroids and exploration encounters. Exploration systems add ships and stations to discover, capture and conquer, while cargo ships, factions and AI-controlled threats offer other things to interact with or defend against. The Visual Script Editor lets you create missions, game modes and campaigns.

Systems and survival

Electricity, power grids and generators supply bases and ships. Oxygen and hydrogen support life systems and thrusters, while weapons and combat blocks equip ships for battles and bases for defense. Other tools include GPS, remote control and voxel hands.

Modding and scripting

Steam Workshop integration supports worlds, blueprints, mods and scripts. The C# modding API can change game behavior and add systems, while programmable blocks let you create in-game automation and custom logic. Mods can also add custom textures, models and other types of content.
