10 Years After is a post-apocalyptic survival horror/ RPG by new indie dev Ten Tree Games.
Lag Studios' first-person adventure game where players traverse the 1000-room mansion of the cute ghost girl, Spooky; there they encounter disturbing specimens and various send-ups of classic video game horror and modern "YouTube-bait" horror tropes. Currently in Early Access, but free to play.
Absolutely horrifying game and a nod to Lovecraftian horror. Wish more similar games came out.
