Robots have been developed by nomadic alien races to perform high risk jobs to decrease loss of life. One day, for an unexplained reason, the robots turned on their creators. They now attack and kill any aliens they come across. The three alien races join forces against the robots. You are a criminal locked up in a ship when the robots attack. You wake up with massive gaps in your memory. After you escape, the alliance leaders approach you for help. You are sent on missions to take out the robots' leaders and sabatoge their war effort. After a few missions, you discover that the robots were reprogrammed and can be turned back. The next levels include good robots that help you fight the hacked ones. Eventually evidence shows that you are the cause of the evil robots. The alliance sends all the ships they can muster to attack the station with you onboard. You rush to find the main control room. After defeating the final boss, a horde of robots rushes in and you are killed. The aliens end up victorious because of your actions.
