"Armageddon It: NASA Kerbal Mission Blasts Off" -

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 Flight Simulation ensures everything will fly (and crash) as it should.

  • Take your Kerbal crew out of the ship and do Extra Vehicular Activities

  • Fly out to Moons and other Planets

  • Procedural Terrain delivers detailed terrain at a vast scale. The Kerbal Planet is 600km in radius!

  • Mod-enabled, allows players to create new content and modify the game.

  • Ship systems. Keep an eye out for engine temperatures and fuel levels, and try not to explode.

  • Build ships with multiple stages, and jettison parts away as they burn out.

  • Full control over the staging sequence allows for complex ships and advanced functionality.

  • Dock spacecraft together to build Space Stations, Massive Starships, or even surface bases on other worlds.

  • Manage your crewmembers, hire them, and send them out into space and make them into heroes.

  • Research and Develop new technologies to advance your Space Program.

  • Take on Missions to attract interest in your Space Program.

  • Discover new worlds and expand the scientific knowledge of Kerbalkind.

  • And a whole lot more!

Very fun game

kerbal space program is a game about building rockets and planes with the main goal of exploring the planets and moons in the solar system. the game can be played in a casual sandbox mode with no restrictions in terms of part avaliability or funds, science mode, where your only restriction is getting science to unlock parts, and career mode, where you have to build up your space agency from the ground up and manage science and funds used to build rockets and upgrade facilities. there is a steep learning curve after you get past the initial launch into orbit phase of your space adventures, but that can be overcome by watching tutorials or using autopilot mods if you just want to get out there. overall its a great game and is enjoyable for anyone with a passion for engineering and space.


Making space fun!

Rockets, physics, gravity, and a ton of fun! The mods make this game a lot more fun and kind of defy some of the physics but who is really all about that hahaha. My friend is a huge fan of this game and I love messing around with him on it all the time. Loads of fun and can really teach you a lot about spaceships.


An excellent simulator.

This game has finally come out of Early Access, which alone shows how good a game is, due to it being fully fledged. This game offers a wide opportunity of construction, the most fun personally being jets and moon landers. The game offers many objectives such as building a humongous space station or landing on the moon successfully with your kerbals. The physics and technicality of the game are simply amazing, whilst it can be a little hard to learn ( I would recommend watching Scott Manley's videos on Kerbal). I extremely enjoy this game and recommend this game to anyone.


Fustrating Fun

For a simulation game the parts simply add up. the Graphics could be better, but in a complex game as this, the graphics can take second to physics. music is catchy without being drone. A plethora of replay ability. but one thing that stands out the most is the learning curve, you must learn the game by playing and failing and trying again. Great on sale and worth the early access price.


awesome game

Kerbal Space Program is a game in which you can create planes or rocket ships to go to space and explore new places. The game has great graphics, they run smoothly, even with a gigantic map. The sounds are good for the game, but could have been better since they are very simple. The gameplay is great but it is really hard to understand the controls in the beginning, since it is complicated to play the game. Overall, it is an awesome game that I recommend to all people out there who are into simulation and vehicles creations game, since this is a great combination of both worlds. The only thing is that the player needs to be patient to learn how to play and create, but besides that, it is really fun!
