Deep Blue is a TurboGrafx-16 shoot ’em up set beneath the ocean’s surface. Your vehicle is a fish-shaped submarine, and its opponents are waves of aggressive sea creatures. The action scrolls horizontally, with the craft’s ability to withstand and recover from damage shaping the way each attempt unfolds.

Gameplay
Move through the available space and fire at marine enemies before they surround the submarine. Collectible items provide different weapons and improve the craft, but reaching them can require crossing a busy part of the screen. The submarine’s eyes change to show its damage level, giving you a visual cue for how much danger you can afford. Safe periods allow its condition to improve, while another collision can weaken weapons and briefly disrupt movement. Because a hit affects both survival and equipment, several mistakes in quick succession can leave the craft struggling to clear a path. The screen also scrolls vertically as you move, offering room above and below the current view. Each stage asks you to manage that space, find useful pickups, and reach the boss with enough strength remaining to finish the encounter.
