I'm few hours in and I'm enjoying it so far, but it has some problems. I think introduction wasn't so great, it shows smaller budget with things like simple animations and I encountered annoying bugs. It's alo quite overwhelming at first, but it's maybe a good thing, I mean, when I was swarmed by Aliens it was pure chaos, I didn't even know when one of my marines was snatched away and it was great moment, like hive scene from Cameron's movie. I think that this game evokes suspense of Aliens far better than any shooter can.
