Space Engineers is an open world sandbox game defined by creativity and exploration.

It is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, wheeled vehicles, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel through space to explore planets and gather resources to survive. Featuring both creative and survival modes, there is no limit to what can be built, utilized and explored.

Space Engineers features a realistic, volumetric-based physics engine: everything in the game can be assembled, disassembled, damaged and destroyed. The game can be played either in single or multiplayer modes.

Volumetric objects are structures composed from block-like modules interlocked in a grid. Volumetric objects behave like real physical objects with mass, inertia and velocity. Individual modules have real volume and storage capacity.

Highlights

• Planets and moons – fully destructible & persistent, volumetric, atmosphere, gravity, climate zones
• Game modes
  - Creative – unlimited resources, instant building, no death
  - Survival – realistic management of resources and inventory capacity; manual building; death/respawnSingle-player – you are the sole space engineer
• Multiplayer
  - Creative and survival mode with your friends
  - Cooperative and competitive
  - Privacy customization: offline, private, friends only, public
  - Up to 16 players
  - Dedicated servers
• New game options
  - Scenarios - offer linear story with action-packed gameplay, while the majority of Space Engineers scenarios feature unique sandbox environments where players create their own challenges.
  - Workshop worlds - offer worlds created by other players.
  - Custom worlds - offer variety of customizable worlds where you can start your own scenario.
• Customizable character - skins, colors, community market, male and female character
• Ships (small and large) – build and pilot them
• Space stations
• Super-large worlds – the size of the world to 1,000,000,000 km in diameter (almost infinite)
• Procedural asteroids - an infinite number of asteroids to the game world
• Exploration - adds an infinite number of ships and stations to the game world; discover, explore, acquire and conquer!
• Drilling / harvesting - use welder to assemble blocks from components; use grinder to disassemble and reuse components
• Deformable and destructible objects – real proportions, mass, storage capacity, integrityVisual script editor - players can create missions and game modes which can be played by other players. Capture the flag, death-match, racing or campaign driven missions - all can be done by using the editor, with your own rules and designs! Even main campaign and game scenarios were created in this tool.
• Building blocks - over 200 blocks (gravity generators, jump drive, turrets, doors, landing gears, assembler, refinery, rotors, wheels, thrusters, pistons, wind turbine and many more)
• Programmable block - allows players to write small programs that will be executed in the game
• Electricity – all blocks in a grid are wired in an electrical and computer network; electricity is generated by nuclear reactors or various power sources
• Gravity – produced by planets and gravity generators. Spherical gravity generator also available.
• Symmetry/Mirroring – useful in creative mode when building structures that require symmetry
• Weapons – automatic rifle, small and large explosive warheads, small ship gatling gun, small ship missile launcher
  Steam Workshop – share your creations with the Community (upload and download worlds, blueprints, MODs, scripts)
• Localized interface
  - Official localization: English, Russian, Chinese, French, Spanish, German, Italian, Portuguese-Brazil
  - Community localization: Czech, Danish, Dutch, German, Icelandic, Polish, Spanish-Spain, Spanish-Latin America, Finnish, Hungarian, Estonian, Norwegian, Swedish, Slovak, Ukrainian
• Cargo ships - auto-piloted vessels (miners, freighters and military) that carry ore, ingots, constructions components and other materials from sector to sector. They can be looted but beware, they often contain booby traps!
• Oxygen - take off character's helmet, generate oxygen out of ice by using the oxygen generator
• Hydrogen - hydrogen thrusters, hydrogen tanks and hydrogen bottles
  Factions - create and join factions, determine ownership of blocks and manage the relations between them (hostile/ally).
• Remote control – control ships and turrets without being inside
• Modding - world files, shaders, textures, 3D models
• Modding API - brings a lot of new possibilities to modders and allows them to alter the game by writing C# scripts which have access to in-game objects
• Blueprints - save your ship or station on a blueprint and paste it into your game
• GPS - create, send, receive and manage GPS coordinates in the game
• Voxel hands - shape and form the asteroids and change their material (creative mode only)
• Xbox controller support
• Sounds – realistic and arcade mode
• Manual building in survival mode –
• Planetary bases, outposts, cities
• First-person & Third-person

Space Engineers utilizes an in-house built VRAGE 2.0, realistic volumetric-based physics engine: all objects can be assembled, disassembled, damaged and destroyed.
