In the Hunt is a horizontal scrolling Submarine Game from 
Irem
The Story: The player is on a mission to destroy the Dark Anarchy 
Society (D.A.S.) in an post-apocalyptic Japan, after the polar ice caps 
have melted. The only remaining evidence of earth society are a sunken city, 
replete with submerged skyscrapers, and a Japanese town built on oil rig-style 
platforms. The rest of your journey will take you through underwater caverns and 
ruins, and finally, the flooded base of the D.A.S. itself. 
In the Hunt is a furious two-player submarine-based 
shoot-em-up, it looks like Metal Slug, plays like Metal Slug, 
it is essentially Metal Slug with the ability to move all over the 
screen. Visually, In the Hunt looks very nice, with its cartoon-style 
graphics, excellent animation, and careful attention to details. In the second 
level, your submarine can blow up quite a few background objects, which often 
causes (tiny) people and animals to run out and plunge into the water below. You 
can even decimate the buildings in this stage with no repercussions.
