METAL EYE

In Metal Eye, the player takes the role of a young weapons expert named Findhill. His father was apparently involved in a project that dealt with creating artificial life forms. But recently he has disappeared without a trace. Findhill remained alone, in a small town surrounded by vicious monsters. He wants to become a hunter, just like his father once was, to get rid of the monsters roaming the wilderness, and get to the bottom of his father's disappearance and his mysterious project.
