Over on Cardboard Warriors, a great web board for people who create and use paper miniatures, the user Yifferman posted some Alien Xenomorph paper minis a few years back.
Recently I ran a one-shot GURPS adventure set in the Aliens movie universe from the Game Geekery Blog. In the scenario, the players are Colonial Marines battling swarms of aliens. So I needed to print a lot of aliens quickly.
To make a swarm of aliens to fight I created a cutfile for use with my Silhouette paper cutter. This is a machine, usually sold in craft stores, that can cut paper based on digital files.
In case anyone wants to make their own alien horde, the cutfiles are posted here:
