Deep blue Katei Shinwa is an horizontal shooter by Pack In Video. The action takes place deep under the ocean and the player takes control of a fish-shaped robotic submarine. Its mission is to rid the oceans of all the evil fishy monsters that invaded it, and this through four long and perilous levels. Innumerable schools of fish and other sea creatures appear at random and relentlessly attack the robot-fish. Its first line of defense is a cannon that can fire small bursts of energy. More weapons are available for the sub's destructive whim though - blue moon fish are scattered around each stage and drop special items such as extra health, speed boost and new weapons (Light Bullet, Swirl Cutter or Bubble Beam). Each weapon can be upgraded up to three times, but getting hit will lower their power by one level (as well as the speed of the sub). Although the sub comes with only one life, his energy level is always displayed through his glowing eyes - if they glow blue then he is in good health, red and things can soon turn bad. The sub also automatically (and slowly) refills its energy as long as it doesn't fire its weapon. Meaner and larger creatures await for the player at the end of each level, and range from large hungry fish, giant jellyfish and mean nautilus.
