Kerbal Space Program is a multi-genre game where players create their own space program. In KSP, you must build space-worthy craft, capable of flying your crew out into space, without killing them. At your disposal is a collection of parts, which must be assembled to create a functional ship.

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.

  • 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 ship’s setup 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 crews.

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

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!


Houston, we have at least eight problems

Have you ever wanted to be a rocket ship engineer? Well, how about making things explode, sometimes in the air? You can do both here! I hear rumors that you can get to the moon, the moon! I haven't made it there, I'm not even certain I've ever made exit velocity. Regardless, this is a great game for tinkering, or exploding, or tinkering and then exploding.

One thing I will say about this game that it does exceedingly right is the physics. And it should be no surprise, being a game where physics is practically the thing you're manipulating.

I remember that as a kid I was fond of drawing rockets and spaceships. Later on, this same love moved on to paper plane designs. Something about a heavy object weighing tonnes captivated my mind as a child, and, being the nerd that I was back then, read up a lot about aerodynamics and stuff like that.

Seeing this game for the first time, I was filled with a good deal of nostalgia. Now I can bring those drawings and creations to life with the great deal of customization available to me. I've outlined my gameplay: flying around the Earth is my first priority, then leaving the Earth's atmosphere is next. Then it's a matter of orbiting the moon, landing on the moon, then eventually, should I be lucky enough, I wish to travel past our solar system.

With Kerbal Space Program, the farthest reaches of space are not so far. I only wonder what the limitations of the game itself are. I haven't gotten that far yet. But I'll be sure to call down from space to tell you all what it looks like (spoilers: it's amazing.)


This is a fun simulator

This game is a silly, yet rather interesting simulator for space travel. While it is a bit silly, don't let it fool you it is rather realistic, which is good. Most simulators today are more like just games while this one is more like learning and teaching. You must make a space craft and go around space in your shuttle, which you must figure out what makes the best impact. They have many types of pieces of shuttle. Like cones, gastanks you can make it so you can have stages. You must then orbit the earth to get into a moons gravity or plantets, to get sucked in and land. Then you can explore that planet. It is in EA so don't expect it to be perfect it does lag sometimes, and get some issues ut all in all it is really fun and interesting to learn. Lets go to the space exploration center nooowww.
