Let's play "In the Hunt" A PS1 classic

In the Hunt is an underwater-themed scrolling shoot 'em up game, with its gameplay described as a cross between Metal Slug (1996) and the classic shooter R-Type (1987). The plot involves an organization named the Dark Anarchy Society (D.A.S.) attempting to launch a superweapon over a post-apocalyptic earth. To stop this, a submarine named the Granvia is deployed to stop the D.A.S. and protect what is left of the planet. The game does not scroll automatically, as the player is able to move the Granvia at their own will. In each level, the objective is to destroy enemies, avoid their projectiles, and defeat the end level boss. The Granvia begins the game with forward-moving missiles, which defeat most enemies with one hit. Missiles can be launched upwards to destroy enemies above the player. Destroying specific enemy types rewards the player with a power-up, which give the Granvia access to new weapon types. Weapons include a powerful machine gun, a wave cannon, and a "cracker" shot that launches a barrage of bullets at enemies.Some enemies drop red orbs embossed with stars, which award bonus points when collected. The game has multiple endings.
