So Aliens: Colonial marines is quite possibly one of the worst games to come out recently. And I bet there are a heap of people out there still wanting to scratch that marines vs aliens style gameplay - and NS2 could be the itch scratcher they need. UWE should take this opportunity to do a trailer or some kind of quite promotion to get those people on board.
btw here are some comparisons of the Aliens Colonial Marines game being compared to what the advertising material was and what the actual released game looks like.
Oh and in multiplayer the wall walking is laughable
