Just finished playing through this. I wanted to enjoy it as much as you guys seem to have but just couldn't, it was just ok overall I thought. The combat never really crossed the line from annoying to fun for me, you never end up feeling like a typhon smashing badass - maybe that's the point and the odds are always stacked against you to make things scarier, but then being scary wasn't something it was good at either (even with the mimics, which seemed to spawn out of my view cone most of the time rather than presenting any jump scare moments). The space sections were frustrating and disorientating, the little alien pods that race up to you and explode were the worst. There was a point in the midsection of the game where
I also spent the last few hours of the game simply sprinting between airlocked sections to progress the story, which was normally a case of running for about a minute and then waiting for a two minute loading screen to disappear (on PS4) then running to the next loading screen and repeating. Really the segmentation of the world in this sense took away from the immersion a bit. I could've hung around in those areas to fight the aliens of course but the game never gave me a reason to do so, maybe if the combat was more fun and there was a levelling mechanic of sorts I might have.
At the end I also reached a point where the game wiped the option for every to complete a bunch of side quests without warning me that progressing with the main quest would force this, which was a bit annoying though I probably wasn't going to attempt them all anyway. On the plus side I thought they had some interesting ideas such as the recycling technology, fabrication and the mimics, and I liked the fact that you could find everyone on board the ship if you wanted to and see what happened to them and the looking glass stuff was cool. I still found it interesting to play through in the end despite the general frustrations above.
