The Denver Police Department answered the alarm but incorrectly arrived at IllFonic's address, handcuffing three of its employees at gunpoint before the error was resolved.

[15] However, legal battle surrounding the Friday the 13th franchise rights was in progress, causing IllFonic to cease development of new content for the game by June 2018.
