I agree with what OP said. I would also add that there were some occurrences of absolutely terrible decisions from the designers that made the game extremely frustrating and feeling cheap in some parts.

Communication to the player was absolutely terrible at parts. I remember being often left wondering wtf I was supposed to do and where I was supposed to go next, wasting time wandering around.

There were a few instances as well where the gameplay mechanics were extremely inconcistent which left me feeling cheated and made the game extremely frustrating.

I specifically remember a part relatively early in the game where it looked like I was supposed to sneak past a patrolling security robot. It was shown pretty clearly earlier that these robots are supposed to be bullet proof and that they will attack anything that moves. I sneak past it and encounter a cheap scripted moment where an infected human blocks your escape and forces you back towards the robot. Several deaths later I determine that trying to fight or run past the infected results in the robot detecting you and killing you. So I thought I would make clever use of what I had learned so far and hid from the infected and waited for the robot to take care of it for me. Turns out the robot completely ignored the infected human in contradiction to what I was told by the game, which got me killed again. Many frustrating attempts later I realized that you could just shoot the robot in the head to kill it even though earlier I saw another robot being shot at by security guards with no effect.

There is another part where you have to go to different points in a room with walkways surrounded by water. In it is an invisible monster that will randomly attack and kill you instantly. I died many times in there again, trying to figure out what triggers the monster to attack and insta kill you and how to avoid it. I tried sneaking, I tried running, I tried different paths, the attacks seemed to happen completely randomly. I managed to beat the area by pure dumb luck without ever figuring out what the trick was supposed to be.

Also there are a lot of tired and overused cliches. The vent crawling portions tried really hard to be scary but you realize early on that nothing ever attacks you in them and that they are in fact the safest part of the game. Just hold the W key and wait. And then they keep using that trope again and again to a point where you end up laughing at the game's misguided attempts to scare you.

Those were boneheaded design decisions that made the game feel like a cheap bargain bin game. Which is a shame because it clearly was made with top notch graphics.

I didn't play it but that jives with what I heard, plus buggy
