Deep Blue

The ocean is under attack by mutated fish and other aquatic creatures, but a special underwater vehicle called the A.N.G.E.L. Fish Attack Sub is on its way to stop them. This heroic sub is equipped with various power-ups that help it navigate through four challenging scenes of aquatic danger.

With its arsenal of attack modes, including the Pulse Shot, Swirl Cutter, and Bubble Beam, the A.N.G.E.L. can take on even the most formidable mutant fish. However, it's not invincible - the sub's health is indicated by a color-coded system in its eye, and when it reaches maximum damage, the sub explodes, ending the game.
