688 Attack Sub

Computer Gaming World in 1989 gave the IBM PC compatible version a positive review, noting the game was designed to be a fun game, as opposed to a realistic simulator, and concluding that it was "this reviewer's personal candidate for 'Game of the Year'". 1992 and 1994 surveys in the magazine of wargames with modern settings gave the game two stars out of five, stating that the game was closer to World War II than modern submarine operations, and criticizing the "unrealistic" emphasis on periscope target acquisition. Compute! included the game in its list of "nine great games for 1989", describing it as "swift and exciting as any Mach 2 flight simulator". The magazine praised the game's graphics and two-player modem option, but criticized the lack of more than ten missions.

Mike Siggins reviewed 688 Attack Sub for Games International magazine, and gave it a rating of 7 out of 10, and wrote that "the appeal of using modern weapons soon wears off and one is left with only the different situations to add spice. Overall though, it is a good game on an unusual topic but would benefit from a second edition".
