War is hell: The scent of cordite, the clamour of artillery fire, the blood and the smoke and the guys from Five Nights at Freddy's popping up randomly to scare you. It's a nightmare made flesh, and something we ought to have grown past as a society, but which remains as a sad holdover from another age (2014, release year of Five Nights at Freddy's).
Or, at least, that's the case in Five Nights at Hearts of Iron 4, a mod/crime from an author named Krumtum that you can currently find over at the Hearts of Iron 4 Steam Workshop page.
