There won’t be an Adult Agony Patch due to legal issues, Polish developer Madmind Studio has announced.

Agony is an adult-rated title, and will feature explicit gore, intense violence, heart plucking, brutal sex scenes, and more. To protect the game from any kind of censorship, Madmind initially announced that a free 18+ PC patch would be released. “Agony is a game for adult customers. We are doing everything we can to protect this game from any kind of censorship”, the developer wrote.
