What is 688 Attack Sub?

688 Attack Sub on SEGA Genesis is a submarine simulation game that originally hit MS-DOS and Amiga before MicroProse brought it to Sega's 16-bit console in 1991. Published by Sega, this port simulates Cold War submarine warfare, putting you in charge of a nuclear attack sub. It's not an arcade shooter or a fast-paced action game; it's a methodical simulator where patience and planning matter more than reflexes.

How to play 688 Attack Sub online

Getting Started

When you boot up 688 Attack Sub, you'll first see a menu where you can choose a mission or a training scenario. Start with the training to learn how to manage sonar, periscope, torpedoes, and your submarine's speed and depth. The core loop involves navigating a realistic sonar display, detecting enemy ships and subs, then closing in to engage with torpedoes while avoiding counter-detection.

Managing your vessel is key: you control heading, speed (ahead or reverse), depth, and even silent running to reduce noise. The interface shows a lot of data at once - heading, speed, depth, sonar contacts, and weapon status. Take your time reading the manual or on-screen hints if available; rushing will get you killed quickly. Stealth and careful sonar interpretation matter more than twitch reactions.
