Kowloons Gate, a japanese adventure game for the PSX.
is about negative feng-shui bringing back the Kowloon walled city to the real world and the mc has to send it back to the realm of yin. Pretty weird looking and uses the concepts of feng shui, interesting mix of cyberpunk and paranormal concepts. I dont think theres an english patch tho, the game was planned for an english release but it never happened so is japanese only. Theres some playstation vr thing about it but i dont know if is avaible in america or if its an actual adaptation of the game.https://www.youtube.com/watch?v=xEgBswY6_tk
Garage: Bad Dream Adventure
You are a guy trapped in a weird world called Garage, a dilapidated industrial shanty town suspended over a sea of sewage and inhabitated by weird mechanical creatures that look like fetuses. The game is about trying to escape the world by meeting characters who may help you, upgrading your body and finding stuff that reminds you of who you are. The health system is called ego and if you run out of it the npc's kill you since you dont look like one of them to them anymore. No jumpscares nor spooky monsters, just a weird wolrd that imo nails the atmosphere of a nightmare, a weird world with its own internal logic that is more depressing than scary.
Was lost media for a while but it was found and recently localized, mobile only tho. https://www.youtube.com/watch?v=8F8eT8oNpT0
Hellnight (Dark Messiah in japan)
You are a japanese guy taking the subway when it suddenly derails. Starts out as an standard horror game where you are running away from a weird mutant monster but gets weird really fast when you encounter underground colonies and stuff about an end of the world prophecy. You can get different companions thru the game and the ending depends on which you finished the game with.https://www.youtube.com/watch?v=bLmYeFrmdco
