AddForce

AddForce takes you to a imaginary miniature solar system where you can travel between planets while you are affected by gravity. You should be aware not to run out of oxygen, fuel or rocket ammunition. These can be obtained by destroying AA Turrets placed on the planets. Avoid crashing into the land, though - that could cost you lots of HP - so try and maneuver carefully. Planets are not only orbiting the Sun as in real life, they are located in random positions to the solar system's main plane; making visuals more fascinating, and reducing distances at the same time.
