Played this to finish. Cheats was not really necessary.
It was a boring experience. and just like others said. Poorly designed backtracking, and not many types of enemies. The Story made no sense. You instantly know you are a Biological Artificially Created Lifeform, of some kind.
The game is not really "Horror" type. You got Guns. You shoot, things die. None of the enemies are particularly interesting. The gameplay is nothing to brag about. There is bugs, and they can get from mildly annoying to breaking. The Camera and Gun Controls are poorly designed and frustrating.
I can give credits to the Sound Design to some degree. What i mean, is that you can notice what Enemies are nearby you, at any given time. They give off Movement Sounds and Sounds that gives off what type of Enemy they are, so you are prepared to swing around a corner and shoot off one of the exploding ones, before it gets too close, and they damage and kill allies too.
You CAN use the Crystals to your advantage. To lock off enemies in another section of the map. This can give you time to prepare. If you are a bit intelligent, you can play this on the hardest difficulty (but why would you, when the game is not that fun?) and still come on out top, if you use the Map to your advantage, and avoid tight corridors and corners. Never stray too close to the wall, so you do not accidently shoot the wall, as the Gun Camera is messy.
The Story is a mess. I am not going to spoil anything, but if you use your brain for a bit, after the 2nd Mission. You can understand some heavily suggested Storytelling.
The Game suggest it has "Horror". It does not have that, as i stated previously. Nothing feels truly "Horrifying". There are Pregnancy in the game, but it is heavily limited, especially to the Scout Spawners, who does Egg Laying, or so i think. Other than that, there really is nothing to mention of Kinks/Fetishes.
Conclusion: Unimpressive. I can see the Talent of the Creator, to some degree. I just wish he could make an actually interesting Game, and hope this was a learning experience, if anything.
Take care.
