We can now confirm that there was an error in the original submission in which a video sent alongside the game (depicting the scene) was from an alpha build of the game and not representative of the final version of the game. This was not supposed to be submitted along with the game originally.
The same game code that was submitted originally was submitted a second time without final video footage and received a R18 rating. One version of the game will release worldwide and it will include the scene in question.
You can find the full statement from Red Barrels below:
“The original submission of Outlast 2 sent to the Australian Classification Branch contained the final game code and a video file for reference taken from an Alpha version of the game. This video file should not have been sent along with the game code, as its content was not representative of the final game.
In the second submission, the same game code was submitted with a video file reflecting the final game content. The game was then approved for release with an R18+ rating. There will be only one version of Outlast 2 available worldwide.”
