Alien Isolation is a game that will never let you feel safe even for a minute. I love the never ending tension. Want to save your game? Well then you have to make sure, the Alien is not in your vicintity, as it takes a while and leaves you defenceless until it's finished. Or you try to sneak away from the Alien while it moves in the opposite direction of you. Every step you take feels tense as it could just randomly decide to turn around and kill you. You can't just memorize the paths it takes and then sneak past it without fear of being spottet. It's A.I. randomizes its behaviour. Many don't like it for that fact alone, for me it's what makes it the unique experience it is.
Soma has one of the best stories not just in horror, but in games as a whole. That questions if you really are who you are, and how you can be certain of that. It's desolate underwater facilities have a nice atmosphere. I even like many of it's encounters. Sure they aren't the best in the genre but they get the job done in creating tension. I also had to swallow hard, a few times, as i learned about the fate of the few remaining survivors. The ending will also stay with me for a very long time.
Resident Evil 4 is the game i bought the gamecube for. It's still the best survival horror game with a focus on action, that i've played. It has the jump scares that are so common for the genre but because it controls better than previous titles it makes them not as aggrevating, if you should die to them. I also care more about the characters in this entry then any other Resident Evil, with the exception of 2 maybe. I mean i even like Ashley. It's highlight are certainly the boss fights though. I don't think it had a single one that i disliked.
