So I had my first go of this last night I started on hard difficulty (I'm around 3 hours in I think) & they have absolutely nailed it, so refreshing to play a survival horror game that gives you the tools to survive but
still makes you feel weak & constantly on edge.
I also had a particularly great moment with the xenomorph, after a brief encounter with it for the first time I headed back to a big room I had previously visited (my objective is to access a door on the far end) as I step through the door I hear frenzied shots going off, so I run towards the nearest place which has a massive window looking down into the room just in time to see it pounce from a large distance onto a guy and tear him apart.
I wasn't hanging about though so I continued forward down a small set of steps where I see a door that's hackable (mini game for this is really good) but I don't seem to have the necessary upgrade/device. Thinking I hear the beast nearby I cower in the corner for a moment in a terrible hiding spot hoping it doesn't come down the steps as I'd have no way to escape, I risk taking a peek and see that it's all clear I slowly crouch walk my way down a walkway towards another set of stairs leading to my objective I take one last look back from where I came only to see it checking the area I was just in but I reach the door nervously hack it thinking I might die at any minute but I make it through.
I either sighed massively in relief or finally decided to breathe, great stuff!
