About this game
688 Attack Sub is a classic modern submarine simulation which puts you in command of either the American Los Angeles or the Soviet Alfa class nuclear-powered submarines.
Most of the systems you would expect such as sonar and periscope are featured and nicely presented in VGA.

The game offers ten missions for both the Soviet and American side in a Cold War scenario, that grows progressively hotter.
Nice to see that the two sides' submarines have their own graphic sets in the game, even with some pseudo-cyrillic labels on the Russian side.
About Sega Genesis
Known as the Mega Drive outside North America, the Sega Genesis (1988/1989) was Sega's most successful console and Sonic the Hedgehog's original home, fueling the "console wars" era against Nintendo's SNES. Genesis cartridge collecting is well-established: common sports and platformer titles are affordable, while sports-license and later-era games with smaller print runs can carry a meaningful premium.

Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
