Hey you guys should make it so the place the aliens reside look alien like. Like what they do in Natural Selection 1 & 2. I feel like it would add to the mood. Have blackish growth everywhere, a few of their home world plants and weeds sticking up from out of the ground; you know that kind of stuff. I mean just having alien assets everywhere without geological change just seems odd especially with a race like these who build stuff on things. Just a thought.
PS: Your Basilisk model still makes me giggle ;)
