Kerbal Space Program

Game description:

Become a commander of a space campaign and control the aliens – kerbals! They are waiting for your command to create the space ships, basing on the experience and knowledge you have. Or those you haven’t yet, but will get very soon through the experiments and investigation of the physics laws and aero dynamics principles. Place your ships on the orbit trying to keep your team safe and send them to the distant planets, continuing to build bases on your planes as well as the stations that will help you discover even more space environment!
