In 2197, an interplanetary mankind encounters a rogue planet passing through the solar system.  Beneath its frozen surface lurks a discovery that threatens all of humanity.  As the human race is brought to the edge of extinction, a failing AI locates a remaining hypersleep pod within lunar orbital Theia's crisis unit chamber.  Once awakened, the last surviving soldier must journey across the solar system to secure the THREAT VECTOR. THREAT VECTOR has a laser focus on the core elements that make classic shooters timeless: ENGAGING COMBAT > easy to learn, hard to master; varied, dynamic and refined. EXCELLENT LEVEL DESIGN > succinct and elegant levels are infused with the rich history of classic FPS design. GRIPPING ATMOSPHERE > ambience and mood so thick you can cut it with a knife. Neutralize the murderous mechs, augmented animals and antisocial aliens that menace lunar bases, orbital facilities and space stations across the solar system with an arsenal of ballistic weaponry, including shotguns, carbines, precision rifles, explosive launchers and high-tech, experimental weaponry.
