Deep Scan

Deep Scan is a 1979 submarine simulator video game developed and published by Sega for Japanese arcades; in North America, it was distributed by Sega/Gremlin. The player controls a battleship on the surface of the ocean attempting to destroy submarines below it, similar to games such as Periscope (1965), Sea Wolf (1976) and Depthcharge (1977). Some arcade cabinets also include Invinco, a Space Invaders clone released by Sega in 1979.^{[citation needed]}

Gameplay

Most of the screen is a side view of the water with enemy submarines patrolling in it. The goal is to destroy as many submarines as possible by dropping explosives from either the left or right side of the ship while avoiding mines launched from these submarines.^[4] A mini-map at the bottom of the screen shows submarines coming from the sides, before they are visible.

Legacy

Deep Scan is a bonus game in the Sega Saturn version of Die Hard Arcade.^[4] Every 200 points earned gives the player an extra credit for the disc's title game.
