Kerbal Space Program Complete Edition Key

In the Kerbal Space Program, take over the leadership of the space program for the alien race known as the Kerbals.
You have access to a range of parts to assemble fully functional spacecraft that fly (or not) based on realistic aerodynamic and orbital physics.
Launch your Kerbal crew into orbit and beyond to explore moons and planets in the Kerbal solar system, building bases and space stations to extend the range of your expedition.
Kerbal Space Program has three game modes.
In Science mode, perform space experiments to unlock new technologies and advance your knowledge of Kerbalkind. In Career mode, oversee every aspect of the space program, including construction, strategy, funding, improvements, and more. In Sandbox mode, you are free to build any spaceship you can think of, with all the parts and technology in the game.
