Red Barrels studios stated they will only release Outlast II if they themselves are afraid to play it.
Several of the game's events were inspired by the Jonestown Massacre.
There is unused audio within the game's files of Father Loutermilch apparently raping Jessica. This was more than likely removed from the game for being too shocking and graphic.
In the teaser, there are two common misconceptions: -The inverted cross is commonly believed to be a satanic symbol. It's actually the cross of Saint Peter; according to the legend, St. Peter requested to be crucified in a different way than Jesus Christ, as he felt that he didn't deserve to die in the same manner as his lord, and the Romans did so. The true Satanic Cross was first introduced in the Satanic Bible, written in 1969 by Anton Szandor LaVey, and it's called Brimstone Sigil, one of the many symbols of Church of Satan. -The cross burning was used as a sign of protest and declaration of war in the past, but has been ever since associated with the KKK, who would burn crosses near the homes of those who they wished to intimidate.
