Hmmm... how about a team of Marines is sent to investigate some... unusual humanoids as the government is attempting to prevent the zombies from spreading further. They find out its really Aliens and Predators who have lured them into a trap explaining why they can't escape. The average zombie being replaced by Xenomorphs as they attack with only Melee similar to the zombies with a boss being a Predator.
