688 Attack Sub is a submarine simulator video game designed by John W. Ratcliff and Paul Grace, developed and published in 1989 for MS-DOS and in 1990 for Amiga by Electronic Arts. A Sega Genesis version was released in 1991 by Sega and was developed by MicroProse.
The player takes command of a US Los Angeles-class or Soviet Alfa-class nuclear-powered attack submarine and plays ten missions ranging from into either Cold War scenarios or combat missions in a hypothetical global conflict.
As modeled in the game, the American submarine has more sophisticated electronics and more weapons. The Soviet boat has fewer weapons but higher sustained speeds.
This was one of the earliest games that allowed two players to play against each other over a modem (or null modem cable).
EA later published Jane's 688(I) Hunter/Killer (1997) .
Copy Protection
The 688 Attack Sub box stated that the game was NOT copy protected. However, in order to start a mission you had to transmit a code to fleet command which consisted of looking up a sub name in the manual and finding the corresponding code. The codes were scattered all through the manual in an attempt at making pirating difficult.
(The game executable was hex edited to remove the code requirement
and versions of this fix circulated on Bulletin board BBS systems
back in the day.
Text file versions of the User Manual also circulated on Bulletin board BBS systems back in the day.)
Installation
The first time you install the game, it asked you for your first name. Your name was then saved onto the game disk so all future installs would use this name. There was no option to change it.

An early submarine game with ten missions which can be played with both American and Soviet attack submarines. The game focuses on realism with several stations the player can use (sonar, weapons, navigation, helm, radio and periscope) but most duties can be delegated to crew members. The graphics are mostly close-up views of the control panels but in some occasions they feature digitized images of surface ships and crew. - "In a full VGA 256 Color!"
