Funny part is the OP post is often deceptive in a lot of threads about the content the game has.  I can understand confusion often when the game content isn't described probably and is missing important tags and such.
This is the least deceptive OP I've ever seen though.  It tells you the goal is to survive, warns you that it's brutal and dark, there's even graphic rape images in the preview, lol.  People coming into this expecting some lovey dovey consensual sex scenes confuse me.  Just the art style alone warns about the type of game it is.  When I saw it, I was like "Oh shit this is going to be dark" and expected most the H scenes to be brutal.  I mean the damn main banner image looks like Lona is standing on a pile of corpses.  Everything dark and muddy looking.  Walls, floors, and people caked in blood and dirt.  I don't know what more you could do imagery wise to warn people than that lmao.
Even for the people that don't read the warnings in the main post before downloading, there are plenty of immediate warnings/hints in game.
