A secret branch of the Army has unleashed a deadly experimental weapon upon the Enemy! In order to neutralize the Enemy's river defenses, you must play a cyborg shark armed with a super-laser. You are programmed to DESTROY all threats: choppers; fighter planes; battle ships; and especially BRIDGES! Charging stations have been secretly placed in the river. You must maintain power in your laser, or you will self-destruct! This is to safeguard your technology from the Enemy. Above all, you are programmed to MAXIMIZE POINTS! You gain points by destroying threats and barriers - for extra points you can destroy your own charging stations, but BE careful. Now Go Forth And Serve Proud.
