The series takes a bold new direction underground. No office, no cameras, just you, interactive tasks, and a cast of highly advanced and highly dangerous animatronics.

The Story

Welcome to Circus Baby's Entertainment and Rental, a sister location where cutting-edge animatronics are repaired and prepared for private parties. As a late-night technician known to the system as Eggs Benedict, you descend into the underground facility to perform maintenance on the Funtime animatronics: Circus Baby, Ballora, Funtime Freddy, Bon-Bon, and Funtime Foxy. What starts as routine repair work quickly spirals into a nightmare as the sophisticated machines begin to hunt you through the facility's vents, stages, and control rooms. With voice-guided instructions, hidden secrets, and multiple endings, Sister Location dives deeper into the twisted lore of the FNAF universe.

How to Play

Desktop Recommended: This web port is designed for desktop PCs. Touch support on mobile devices is highly limited, so playing on a computer with a mouse and keyboard is strongly recommended for the best experience.

Each night features unique, story-driven tasks instead of static office defense. Follow HandUnit's instructions while navigating crawlspaces and different rooms. On some nights you will monitor stages with controlled shocks, play audio cues to distract animatronics like Ballora, crawl carefully through vents while avoiding Funtime Foxy, or hide from Minireenas. Later nights introduce direct interaction, precise timing, and moral choices. Listen closely to Circus Baby's guidance, she may not always have your best interests at heart. The game blends puzzle-like mechanics, stealth, and tense movement sections, with difficulty ramping up significantly toward the end. Custom Night offers even more intense challenges.
