Gish isn't your average hero, in fact he's not your average anything - you see, Gish is a ball of tar. A Sunday stroll with his lady friend Brea goes awry when a shadowy figure emerges from an open manhole and pulls Brea into the ground below. Following Brea's calls for help, Gish suddenly finds himself in the subterranean sewers of Dross, a long-forgotten city filled with twisting corridors, evil traps and some of the most demented creatures imaginable. With his gelatinous structure as his only means of defense, Gish must follow the echoing cries of his damsel in distress deep into the earth below.
