I'm writing an article for an Xbox site I'm a regular on, and my current feature is, well, the concept is up there. So far I've got aliens from Halo, Mass Effect, Half-Life, just doing Prey and I'll finish on Alien Hominid. :D Any more suggestions? I'm not doing Warp. Or The Maw. Mm, maybe. I was considering laughing at the xenos from Colonial Marines. Five may be enough, though.
