Of course, I had to find some sort of gaming application for the movie. I've been looking for "new" aliens to throw into a Doctor Who game so I decided to stat our the unamed alien invaders.
(Revised on 2-11-13: Forgot to give aliens skill ranks. Also, traits for the compatible Primeval RPG have been added. Revis again on 10-10-13, I don't know why I didn't think of the name Blue Tooth. Snagged name from this post over at A Field Guide to Doomsday.)

Blue Teeth are blind, gorilla-sized aliens with spiky black fur. Their fur is so dark that it reflects no light. However, the creatures can be detected in the darkness because of their multiple rows of glowing blue teeth. Blue Teeth are simple bestial creatures. They travel through space likes spores, drifting on solar winds until the find a suitable planet. When they find a such a place, the female releases a strong pheromone that attracts the males.Any none Blue Teeth covered in the pheromone will be hunted mercilessly as prey. The dangerous creatures can be quite formidable and more than one community has been destroyed by an infestation.
