Alien vs. Predator/Walkthrough

Story
San Drad, California has been overrun by Xenomorphs. Two soldiers were caught in the town during the initial alien outbreak and were abandoned by the rest of their team as well as their superiors, and are cornered by a swarm of xenomorph drones. Before they can be killed, two Predators appear and destroy the xenomorphs, saving the soldiers (who are assumed to be humans but are later revealed to be cyborgs judging by their Character's Profile during the game's attract mode). The Predators offer an alliance with the cybernetic humans, in order to stop the Xenomorph infestation. Eventually, it is discovered that the Alien presence on Earth (and the subsequent swarm that overran San Drad) was the result of an experiment headed by an USCM colonel in conjunction with the Weyland-Yutani corporation. In the end, the Alien Hive on Earth is destroyed in a scene similar to that in the ending of the fourth Alien film, Alien: Resurrection - A military ship is set on a course that causes it to crash into San Drad, destroying the Alien threat along with a good portion of the western US, if the explosion in the ending credits is to scale. The story ends with the veteran Predator (Predator Warrior) breaking off his wrist blade and giving the piece to Linn and Dutch. When asked why the Predators helped, they jokingly light their Plasma Cannon sights at them with the leader saying, "They'll know." before departing into space. Indicating their hunting season is over...for now.
