Nothing says "We're building a really good game" like a trailer that has all the awards you were nominated for (but didn't win). So the folks behind Alien: Isolation came out with a trailer that shows how well received their game was (it was well received). For a game based on a concept we all know, with predictable behaviors of the antagonist, it still looks like they're doing a nice job of ratcheting up the "creepy factor", which is what made the original movie so good in the first place.
