The issue with me is, I've already talked about all the spooky games i've played in this thread. I've watched a walkthrough without commentery for an interesting game though. Much like Alan Wake, it has a live action prequel https://youtube.com/playlist?list=PLWjnM4fZ4U8wLxrFXjL-95ME0QJwdz8m8
Anyway, the game is called SOMA.
So, Your an average joe, Working a pretty regular 9 to 5 job. Wake up, Work, Sleep, Repeat. One day things don't exactly go as plan and you get onto a bad car wreck. Your fine, no scratches or broken bones. Just some real bad head trama. You can't really tell thats anythings wrong but you honestly don't have too long to live. You get a call from some scientist for you to volenteer for some program he's running about scanning your brain, You do the thing and get home quickly because you feel kinda sleepy. You go to sleep then wake up. It's time to work! Everything honestly looks fine and you get out of bed, and walk out the door to leave. You expected to get some fresh air but instead you get a futuristic, yet fucked up hallway that obviously is in a state of disrepair. After exploring, things go from 0 to 100 real quick.
The whole game is a total mindfuck. From the underwater setting, To music, humanity, and making choices you don't feel comfortable with this game does well. I kinda dont want to spoil it or talk too much about it but; [spoiler]So earth is fucked, everyones dead and the people that are alive got their brain scanned and put into robots, and are currently on some secret reseach center deep under the ocean. (200 years in the future) The transfer is honestly tramatic and they don't mention or atleast pretend they are still human, and if they realise they are robots they go totally insane. The human crew/scientists got turned into monsters because of nanotech they either touched, or ate because they ran out off food and it turned them into horrible monsters[/spoiler]>>627
