I played it a bit, the first edition, bought the second but never did anything other than play a few times. I have the box and have considered painting up the units with it. Some months back, Nick Reiketa talking about it got me keen to start painting again, which I may do. It was a fun game as I recall, you couldn't see the aliens until they attacked you, right? They were just scanner blips moving behind the walls/under the floors/across the ceiling like in the movie Aliens. Really a cool implementation of fog of war.
