Play 688 Attack Sub Online
You're hunched over sonar screens in a creaky sub, plotting silent torpedo shots while destroyers ping the water above—tense as hell when those depth charges start rolling in. The controls click after a while, and suddenly you're whispering orders to your crew like some Cold War captain.

Game Overview
688 Attack Sub is one of those old-school Sega Genesis games that actually makes you feel like you're running a submarine. You get to pick either an American or Soviet sub and dive into ten missions where you're juggling sonar pings, torpedo launches, and avoiding depth charges—or just let your AI crew handle the boring stuff while you focus on sneaking past destroyers.
The controls look intimidating at first—lots of dials and screens—but after a few minutes, you start figuring out which stations actually matter. The graphics are mostly close-ups of your sub's dashboard, but every now and then, you get these grainy digitized shots of enemy ships or your crew looking stressed. It’s not flashy, but it nails that cramped, tense vibe of being underwater with warships hunting you.
Honestly, half the fun is deciding whether to micromanage everything or just yell orders at your crew while you peek through the periscope. The game’s definitely showing its age, but it’s still weirdly absorbing if you’re into slow-burn naval warfare.
