In Free Mars you are a fighter who wants to free your friends and your planet from a tyrant and his officers. In order to do this, you must first destroy the officers that are in your way. In Free Mars you will use the arrow keys to move and the space bar to fire. You can gain health ups by taking out the officers. Try to get through each level without dying. When your health bar in the upper left runs out your fighter will go for a crash landing on the ground. If you die all the fight for freedom will be over with.
