You oversee the space program of an alien civilization known as the Kerbals. You are expected to send your crew into orbit and outer space, explore your solar system, expand into the universe by building bases and space stations. There are three modes to play. Carry out experiments and advance your technology in the Science Mode, oversee and micromanage the space program in the Career Mode, and build whatever you like in the Sandbox mode as all parts and technology in the game is made available to you. Build vehicles using any combination of parts, and your construction will affect the flight of the spacecraft. Assume the control of the ship, hire, train and manage the Kerbal crew, discover the vast outer space and much more! Kerbal Space Program is definitely an entertaining yet challenging simulation game.
