DIRT - Origin of the Species PC Game

Origin of the Species is a third-person action game with RPG-style character development and a sci-fi storyline of genetic mutation, designed to live up to its Darwinian title. The premise is based on a secret government-sponsored research endeavor, cleverly called "Project G.I. Ants," which is intended to cause insects and other small parasites to mutate into vicious fighting units for the military. The project has been progressing, as certain substances are already being tested and released into the atmosphere in selected areas -- such as the open expanses of Nevada countryside.

Players take control of a Goth-y city girl, nicknamed Dirt, who's on a camping trip with some friends in the Nevada wilderness when a test run of Project G.I. Ants leads to some dangerous, unexpected troubles -- including the ordered elimination of any witnesses in the area. Yet although the airborne agent can turn everyday bugs into ferocious monsters, it also grants Dirt new, superhuman abilities, which become more powerful with her continued exposure to the substance. The plucky young heroine must use her new powers to defeat a variety of mutant enemies and find her friends before it's too late.

This game is also available on PS2.
