In the game spaceplan you must collect probes and generate electric energy for their launch. All you need is to send these probes to a new unknown planet. There is a high possibility that, on this planet, you will be able to generate energy for your space ships. Click to the white square in the left corner of the screen, to generate energy points.
These points will help you to create probes and energy that will help you to reach the next planet. In the right part of the screen, you may open new versions of probes and different improvements that will simplify your way to the victory. Good luck! Generate energy and invade new planets!
