PT Boat Simulator was an improved version of PT-109 (Spectrum Holobyte's 1987 title).
After developer Digital Illusions disappeared from the gaming industry for several years, they returned in 1994 with this improved version of their classic, and highly underrated, simulator.
As in PT-109, PT Boat Simulator puts the player in the role of skipper of the most versatile fighting machine of the WWII era: the PT Torpedo Boat. The interface and controls would be familiar to PT-109 players, but the graphics and sounds were tremendously improved. PTBS also offered many more missions than its predecessor: 45 different historical missions spanning 5 theatres of action in the Pacific and Mediterranean.
