The release of Five Nights at Freddy's Sister Location was the moment that it became clear just what a sequel in the popular horror series could and should do. Taking players out of another security office environment and into the deep, mechanical bowels of Circus Baby's Pizza World, it proved an experience that was as rich in story as it was terrifying. This entry is admired for its bold industry movement, deep enriching of the series myths, and beautiful interpretation on horror.

Sister Location's immediate and most impressive feature, is its innovative gameplay. No longer is it a case of sitting in one spot, this time players must make their way through the facility and keep moving around to maintain things. This turn towards the active adds a strong note of dynamic, immersive horror. Every night brings new and nerve-wracking challenge, from the sound stay (mere footsteps to surviving Ballora's gallery), to making last minute repairs of our animatronic rivals. It's that variety that helps ensure the tension never slackens; the player is always kept on their toes, as every map presents its own set of survival mechanics.

Also, Sister Location is the franchise's high point in terms of storytelling. The game continues to enrich the dark myths of the series with disturbing voice-acting and environmental story-telling. We are greeted to the elusive William Afton and see the tragedy of his daughter, which is such a deep sense of emotion humanizing among all that horror. The like of Baby are given a voice — here both in the literal and figurative sense — turning ready-made jump-scare villains into complex characters with their own ratio of cause. The game's jaw-dropping true ending, exposing the horrifying fusion that is Ennard and his gory escape plan, serves as a master work in psychological terror that continues to feed fan theories and conversation.

FNAF SL steps inside the terrifying new horror elements and lore that spreads the popular Five Nights at Freddy's formula while scaring players familiar. But this audio-dependent game and its complex gameplay may appeal only to the hardcore.

Ultimately, Sisters Location feels like crafted horror. That’s a declaration that true terror is to be found not just in the jump scare but also in the creepy atmosphere of a well-told story, and the oppressive close-up horror of its setting. And doing that, it turned its gameplay on its head to provide something better with a darker, richer and more satisfying story and is now one of the bravest entries in Five Nights at Freddy’s history.
