Play 688 Attack Sub Online

688 Attack Sub came out for the Sega Genesis in 1991, published by Electronic Arts. It was one of the more serious military simulations on the console at the time, offering a detailed, methodical alternative to the faster action games that dominated the platform. You didn't just jump and shoot; you managed systems and made careful decisions under pressure.

You command an American or Soviet submarine, depending on the mission, with the primary goal of completing objectives like sinking enemy ships or protecting convoys. The game is played from a first person perspective inside the sub, where you monitor sonar, check your periscope view, and manage your weapons and damage control systems. The pacing is slow and deliberate, demanding patience as you track targets and wait for the perfect moment to fire a torpedo. The difficulty comes from managing multiple threats at once, like avoiding depth charges while keeping your systems operational. It feels like a genuine test of your focus and tactical planning.
