The Sewer Shark's goal is to travel all the way from home base to Sun City without crashing or running out of power, while maintaining a satisfactory level of performance as assessed by Ghost and Commissioner Stenchler. As in other rail shooters, the train primarily flies on its own, letting the player shoot moles (mutated hybrids of a mouse and alligator), bats, giant scorpions, and mechanical moles. Along the way, Catfish shows the player the way. If a player makes a wrong turn or misses a turn, they will eventually hit a dead end and crash, ending the game. Later in the game, Catfish is replaced by a "crazy-looking thing" that visually guides the player through the sewers.
The ship has a limited amount of energy, which will gradually deplete during flight and when firing. Scorpions also steal the ship's energy if the player fails to shoot them down. This energy can be partially replenished at charging stations. In later areas, the ship sometimes runs into bags of hydrogen that the player has to blow up so Catfish can pass through safely.
At certain times, Ghost or Stenchler interrupt the player to give direct feedback. If players do well, they are allowed to continue and are sometimes given a promotion as a new call sign. Poor performance will eventually end the game. I wish you a great experience!
