I always got spawnkilled in Multiplayer
But I seriously did love the Alien and Predator campaigns
Marine is meh for me
The Alien campaign was great, and the Predator was too.
Marines... Not too much, just like every other shooter out there.
Also, I'm watching a video and the guy did the finisher as an Alien where he stabs his tail into the Marine's eye. It made me remember the eye poke machine.
