Im not great with horrors but i love them. I hate it when i ask people if they found a horror scary and they say "NO". The point of a horror is that is supposed to scare you and thats why i like them.
Space things don't bother me to much, except even horizon that was messed up and awesome.
Back to the game, its pretty jumpy about and hour or two in and i have only seen the aliens tail but you can hear it. If you have watched the films you can recognise the noises fairly early on in the back ground, the audio for the game is amazing.
