This is an Early Access Game

This means the game is still in active development, and can change drastically throughout development. The Early Access program will not only allow the player to enjoy the fantastic gameplay experience, but will also allow the player to make a real difference in how the game progresses.

The team will continue to create new features throughout the process. Those who choose to purchase the game should expect missing content, bugs, incomplete content and, potentially, game breaking problems.

Another brand-new block makes its debut in Space Engineers: A reloadable parachute block for both small and large grid!

Space Engineers is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, 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.

Space Engineers is inspired by reality and by how things work. Think about modern-day NASA technology extrapolated 60 years into the future. Space Engineers strives to follow the laws of physics and doesn't use technologies that wouldn't be feasible in the near future.

Space Engineers concentrates on construction and exploration aspects, but can be played as a survival shooter as well. We expect players will avoid engaging in direct man-to-man combat and instead use their creativity and engineering skills to build war machines and fortifications to survive in space and on planets. Space Engineers shouldn’t be about troops; it should be about the machinery you build.

  Starting Worlds
• Earth Easy Start - start on a habitable planet with a set of basic vehicles. Your survival is threatened by attacking pirates who set up shop within range of their drones.
• Mars Easy Start - become a colonist on a barren, inhospitable planet. Make sure you secure a source of water soon. Also beware of local pirates.
• Alien Easy Start – the alien planet is a place with very sparse oxygen, not enough to breath freely. There is hostile fauna and pirates who want to claim the riches of this mysterious world and are not willing to share.
• Moon Easy Start – You start on a moon orbiting a habitable planet. Your base is under attack by pirates.
• Empty Star System - It is a star system with 3 distinctive planets and their 3 moons. Except for local fauna, planets are uninhabited.
• Easy Start 1 – start on an asteroid platform with one large ship and two small ships
• Easy Start 2 – start in a green asteroid station with several large and small ships (this is a large scene!)
• Lone Survivor – start on an abandoned asteroid platform with no ships
• Crashed Red Ship – your mother ship just crashed...
• Two Platforms – competitive two-team multi-player world
• Asteroids – start in a rescue ship with very limited resources
• Empty World – no asteroids, no ships; suitable for creative mode
  Enemy NPCs
• sabiroids (spiders): can be found on alien planets and on Titan moons. They can destroy metal blocks and attack players. Their favorite hunting strategy is hiding in the ground and un-burrow to surprise their prey. When players kill a spider, new spiders won’t appear in the area for some time. They also store some components inside their bodies from objects and blocks that they consumed.
• pirate bases: can be found either in space or occupying planetary surface. They have bounty hidden inside their containers that players can loot if they get over the drone attacks.
• enemy drones: they spawn automatically from pirate bases and attack the players when they venture into pirate territory
  Ships (small and large ships – build them, pilot them and crush them
  Space stations
  First-person & Third-person
  Planetary bases, outposts, cities!
  Dedicated servers - allow players to connect to a third party host, rather than using a player-host, in a peer-to-peer set-up. The result is a faster connection and a more fluent multiplayer performance with less lag
  Super-large worlds – the size of the world to 1,000,000,000 km in diameter (almost infinite)
  Procedural asteroids - adds an infinite number of asteroids to the game world

Performance Notes
Space Engineers is in development and undergoing frequent optimizations. The performance will get better.
The performance depends on the complexity of your world and the configuration of your computer. Simple worlds run smoothly even on low-end computers, but a more complex world with rich object interactions could overload even high-end computers.

Please read our performance advices: http://www.SpaceEngineersGame.com/performance-advices.html

Minimum requirements represent the bare minimum to run simple scenes and don’t guarantee a perfect experience.
