Ok well, hear me out.
It's one of the best games I've played probably since 'Life Is Strange' and it's prob in my top 10 of all time. I played it through twice (with a mod I recommend second time round).
The AI though... I thought it was so weak! My first issue occurred the very first time the alien got let lose on me - it got stuck running in a circle. This never happened again, but the it was so obvious to me the alien was acting on information it shouldn't have. I understand it being 'tethered' to the level I am on, but if it entered a room I was hiding in, it would stay in there for SO long for no obvious reason. Beyond following way-points and checking if it can hear or see the player I didn't notice a single thing that was advanced about the Aliens AI. I would have really liked it if the alien climbed along the walls or ceiling too, but I understand it was quite an undertaking as it was.
The working Joe androids where similarly useless - if you stood behind a table, centered yourself with the table when the Joe was also centered on the other side, then tapped left/right/left/right it would just continually change direction giving you all the time in the world to make a decision or reload or whatever.
Enemy humans had issues too, I would hide while they looked for me, they would get really close checking the area I am in but not see me, walk away, stare at a wall for about 15 seconds then turn around and just walk RIGHT up to me.
Also "civilian" NPCs you are not supposed to kill. The tram door opened and 2 of them are inside. One see's me and immediately runs up to a wall next to me and just crouches there hiding, while the other is stuck inside a railing in the tram moon-walking lmao! Another guy had his hands set in the gun holding animation so it looked like a finger gun, and he was running right at me. I shot him - instant game over.
The alien was definitely my biggest issue though - at first it was so tense and scary I loved it, but then I got over it and it was just a pain up the ass. The medical facility is one of the worst bits. They spent so much time using original Aliens film material to craft such an amazing environment and I felt like I was getting rushed by this stupid 1 hit kill alien. It's not like I felt a sense of achievement using stealth to get past it because it always just re-appeared and there is so much backtracking. They added all this backstory and info on computer terminals but I couldn't read them because the alien would get me. I ended up having to open them then really quickly hit escape and pause the game to read them.
The mod I used in the second play-through makes the alien ignore the player and I highly recommend it if you are a fan because you can enjoy the levels and environment without it getting in the way.
Based on what I read on the wiki they broke even or made a little profit and so it's unlikely we'll see a squeal which is a shame. I'm amazed they went to the trouble of making their own engine from scratch for it, it looks beautiful but could they not have pulled that off in unreal or unity to save money?
