Secret of the Mimic
Steel Wool's exploration-driven FNAF horror: recover a Fazbear prototype inside Murray's Costume Manor while a shape-shifting endoskeleton hunts you room by room.
What the game is
Not a night-shift game - an exploration horror.
Five Nights at Freddy's: Secret of the Mimic drops the usual cameras-and-doors loop for free-roam first-person exploration. You're Arnold, an exhausted Fazbear Dispatch technician sent to recover prototype tech created by inventor Edwin Murray inside the abandoned Murray's Costume Manor (MCM).
Your tool is the Data Diver - a handheld device that restores systems, reads records and raises your security clearance to open restricted routes. The threat is the Mimic, a shape-shifting endoskeleton that wears different mascot costumes, so every chase plays differently depending on what it's wearing.
Chapter route
Nine main chapters from the construction route to the Tunnels, plus the Underpinnings finale.
| # | Chapter | What you do |
|---|---|---|
| 1 | Prologue | Enter Costume Manor, collect the Data Diver |
| 2 | Manager's Office | Restore power, raise clearance, reach Jackie's box |
| 3 | Jackie Chase | Escape the tunnels, survive the first major pursuit |
| 4 | Big Top Showroom | Repair the elevator, solve the mannequin route |
| 5 | Music Man Chase | Reach Rooftop Access, descend toward the Theater |
| 6 | Workshops & Theater | Build the springlock path through the backstage areas |
| 7-9 | Hospital, Doll Hospital & Tunnels | Deeper wings, the Nurse Dollie sequences and the final descent |
Expect keypad codes, power routing, crane and machinery puzzles - the answers always live in the room's own records, mailboxes and environmental clues.
Endings & 100%
What completion actually takes.
Three endings
Your route through the finale decides the outcome - one requires finding hidden triggers across the run. A New Game Plus playthrough is needed for full achievement completion.
25 achievements
Over a dozen are hidden - mostly tied to collectibles, optional interactions and the different endings.
Collectible types
Presents, mailboxes, recordings and films are spread through every chapter. Some sit outside the shown map areas - check off-path rooms.
No difficulty setting
One universal difficulty - the game is built so every player sees the same scares.
