Description

In Kerbal Space Program, take charge of the space program for the alien race known as the Kerbals. You have access to an array of parts to assemble fully-functional spacecraft that flies (or doesn’t) based on realistic aerodynamic and orbital physics. Launch your Kerbal crew into orbit and beyond (while keeping them alive) to explore moons and planets in the Kerbol solar system, constructing bases and space stations to expand the reach of your expedition.

Kerbal Space Program features three gameplay modes. In Science Mode, perform space experiments to unlock new technology and advance the knowledge of Kerbalkind. In Career Mode, oversee every aspect of the space program, including construction, strategy, funding, upgrades, and more. In Sandbox, you are free to build any spacecraft you can think of, with all parts and technology in the game.

Key Features


  • Build spaceships, rockets, and vehicles using any imaginable combination of parts, each with their own function that will affect the way your spacecraft behaves.
  • Take full control over your ship’s setup to execute complex flight maneuvers.
  • Manage your Kerbal crewmembers, including hiring, training, and sending them into space to become heroes.
  • Discover a whole star system with unique moons and planets, exploring detailed terrain at a vast scale.
  • Send your Kerbal crew outside their ships for “extra-vehicular” activities.
  • Dock spacecraft together to construct space stations, massive starships, and surface bases on new planets.
  • Use satellites to scan terrain and find biomes and other anomalies.
  • Set up communications networks to communicate between your spacecraft and Kerbal Space Center.
  • Research and develop new technologies to extract valuable information and resources from all over the solar system, and much more!

This is the third space game I have bought. Now I can be as irresponsible as I am in any other game, but with green aliens this time. 10/10 game, had fun sacrificing green megaminds to save money on cheap parachutes.

KSP is one of the most fun and chaotic learning experiences I have ever played. It starts off hard and you might need a tutorial but that what makes it so rewarding. the feel when you final reach the mun, Dune, or Jool.

Idk. I'm autistic and really like deep diving into understanding orbital mechanics, space flight, and building space stations. If that sounds like you, buy it.

This game is awesome, and addicting. 3 hours in a single day, maybe more. For it's age it's pretty awesome. Unique moon and planet names (Kerbin, Mun, Duna, Eve, Laythe and so on.), funny aliens called Kerbals. But
