Polaris

Polaris is a 1980 fixed shooter arcade game by Taito. Players control a submarine which can only shoot missiles upward. The goal of the player is to destroy all of the airplanes in each level while avoiding bombs dropped from the aircraft, as well as mines launched by enemy submarines and depth charges dropped from boats that speed by. Versions for the Atari 2600 and VIC-20 were released by Tigervision.

You're the commander of a Polaris class nuclear submarine. Your mission is to defend your country from enemy attack. You must face one to three enemy subs and one to five bombers in a squad. You must destroy the bombers by shooting missiles. After you destroy the bomber squadron, you must face a dive bomber dropping torpedoes that plunge to your depth then move horizontally. After destroying him, you must navigate through a channel, avoiding or torpedoing mines to reach the next level. Occasionally, an enemy destroyer will move across the screen and will drop a depth charge.
