We first expected Five Nights at Freddy's 4 to release on Halloween, and then a little sooner, on the 8th of next month. Well screw all that, it's out now! FNAF 4 released on Steam today for $8/£5.59 (opens in new tab).
Regarding the unexpected release, creator Scott Cawthon wrote (opens in new tab), "Ok, so as many of you already know, I'm bad with release dates. The game is finished. :)"
We haven't had a chance to play the fourth game in the rapidly expanding series of horror vignettes, so we'll take the word of a Steam reviewer for now: "menu screen spooked me 10/10." Well done, menu.
