Sierra Entertainment today announced that Aliens vs Predator: Requiem, a PSP game based on the new film, which Twentieth Century Fox releases on December 25, has shipped to retailers. In Aliens vs Predator: Requiem, players take on the role of an elite Predator carrying an extensive arsenal of exotic weaponry and equipment. Guided by an unquenchable thirst for the hunt, players have one mission: eradicate all traces of the horrifying Alien outbreak on Earth.
