About This Game

In KSP you must build a space-worthy craft, capable of flying its crew out into space without killing them. At your disposal is a collection of parts, which must be assembled to create a functional ship. Each part has its own function and will affect the way a ship flies (or doesn't). So strap yourself in, and get ready to try some Rocket Science!

The game offers three gameplay modes: Sandbox, in which you are free to build anything you can think of; Science Mode, which lets you perform Scientific experiments to advance the knowledge of Kerbalkind and further the available technology; and Career Mode, in which you must manage every aspect of your Space Program, including administration strategies, Crew Management, Reputation, as well as taking up Contracts to earn Funds and upgrade your Space Center Facilities (or repair them).

Add to this the ability to capture asteroids (a feature done in collaboration with NASA), Mining for resources out across the furthest reaches of the Solar System, Constructing Bases and Space Stations in and around other worlds; plus literally thousands of mods from a huge active modding community, all add up into the award-winning game that has taken the space sim genre by storm.

Key Features


  • The Vehicle Assembly Building and the Space Plane Hangar allows players to build spacecraft out of any imaginable combination of parts.
  • Fully-fledged, Physics-based Space Flight Simulation ensures everything will fly (and crash) as it should.
  • Take your Kerbal crew out of the ship and do Extra Vehicular Activities.

I've done more engineering in 3 months playing KSP than in 20 years of career as an engineer.

My 8 year old son broke away from Minecraft today. He sat on my lap while we made a rocket. He asked questions about rockets. We made it into space and he asked, "Are we in space?" We came down and the friction caused our heat shield to glow. His eyes were wide open as we slowed down. We pressed the space bar to deploy our parachutes but were going too fast and our chutes failed. We crashed and he asked if the kerbal was OK. I said yes as I hit ESC and went back to the VAB and changed a few things. A few minutes later, we landed our capsule safely and he had the biggest smile on his face. I haven't heard a word about Minecraft since! Thank you for making this wonderful game!!!

Started playing this game when I was 11, it was too complicated for me. I'd spent over 20 hours trying to reach the moon but always failed.

I'm now 14 and I've finally reached the moon and back.

10/10 - would wait 3 years until I'm mature enough to understand a game again.
