Argo

In Argo, a group of astronauts attempts desperately to survive as they explore a mysterious space station and are besieged by horrible alien monsters. The only hope is to reach the shuttles. However the seats are limited, not everyone will be able to escape. This leads to a frantic every-man-for-itself race, where the others are at best obstacles, and at worst bait to hold the fierce Aliens back while you run...

But be careful: If too many die, the Aliens win! So while this is a competitive game, some level of cooperation will be required, lest everyone lose to the Aliens.
