Theres nothing wrong with survival horror, it's a great genre, what's left of it that is. Having said that, there is one single Alien in this entire game. I don't want to shoot up hoards with an automatic turret or anything but I also don't want to play Hide and Seek the Video Game for 20 hours of Single Player either. That really sucks imo.
Not to mention all survivor horrors tend to franchise and leave those elements behind just like Dead Space and probably more aptly just like Alien and Aliens. Since this is already a franchise, you know the next games going to go right back to tons more aliens to shoot regardless of this one's success.
But again I'll tell you right now, if you think this is going to save anything your wrong. Most people will avoid it based on Colonial Marines alone and those that don't may based on only 1 single alien.
This concept has already been done with Slender Man the game and wasn't a huge success so this won't be anything new to gamers.

You go around trying to survive and escape while having to avoid and run or trap and get away from Slender Man. It's this on earth instead of Space.
