Here's a second Aliens vs. Predator multiplayer trailer showcasing the 'Infestation' mode.
Infestation sees one player go it alone as an Alien Hunter against a group of Marine Prey. The twist is that once a Marine is killed he joins forces with the Hunter, turning on his friends without remorse.
Check out the trailer for the 'Survivor' multiplayer mode as well, or just pick up your pad and get shooting.
The AvP demo goes live today on Xbox 360, PS3 and Steam.
