The Cochise base are making new robots to wipe out man kind forever. You have to stop them. You play the Rangers, (use all ready set characters or make your own) and you start off with different attributes and skills. You have to use your knowledge and your range of skills to eventually stop the robots. Gather information, do whatever you can. Very good game, had me addicted for a week but even then I kept going. The game is a lot better than it sounds. Try it yourself but keep a backup copy just in case!
