Space Engineers is an open world sandbox game about designing, building and testing your own space machines. Construct ships, stations and planetary bases in a fully destructible environment, then explore planets and space, mine resources, survive hazards and engage in combat alone or with friends in Creative or Survival modes.
Play solo or in multiplayer, from small co-op outposts to huge community servers. Start with a simple lander, grow into a mining and industrial empire, or focus on warships and planetary fortresses – the game gives you the tools and physics, you decide what to build.
Space Engineers uses a volumetric physics engine: every block and voxel has mass, inertia and damage. Ships break apart, stations crumble and terrain can be drilled, carved and reshaped, so your engineering choices really matter.
Space Engineers is grounded in real engineering and hard science fiction, driven by realism and plausible near-future technology. Think modern space programs extrapolated into the future: realistic ships, stations, tools and systems where everything is built and simulated block by block. It’s about the machinery you build, not about magic or scripted set-pieces.
