Agony, the demonic horror game, was expected to launch on March 30, but due to delays, developer Madmind Studio has pushed the release back to an unannounced date. This is, in part, due to the violence, torture, and nudity present in the game affecting the age rating. The developers stated on their Kickstarter page that they had to tone down a number of things to accommodate the age rating board. The rating had gone from Adults Only to Mature, in order to be allowed on consoles.
Like with most creative projects, the creator wants to keep their image true. This is why they announced a "special, optional patch for PC that will remove the aforementioned 'censorship'" that players can download after the game's release. Since this will not be an option for consoles, Madmind is offering their Kickstarter backers the chance to exchange their console backer reward for the PC variant, instead.
In order to minimize spoilers, Madmind didn't say what exactly had been censored. They did clarify that everything seen in the trailer (viewable below) will remain in the game, at least. So you can still expect a hellish experience all the same.
