Steel Wool Studios finally dropped us into the deep end of the lore pool with the 1970s-era prequel, and honestly, it's a lot. If you've been following the breadcrumbs since Ruin, you knew the Mimic was coming back, but seeing its origin story in a gritty, analog-horror setting is something else entirely. This fnaf secret of the mimic walkthrough isn't just about pushing buttons; it’s about understanding a mechanical monster that learns from your every move.
The year is 1979. We aren't in a shiny mall anymore. We are in the Central Control and Manufacturing facility, a place that feels damp, heavy, and dangerously outdated.

Getting Your Bearings in the Factory
When you first step into the facility, the game doesn't hold your hand. You’re immediately met with that signature Scott Cawthon-style dread, but amplified by the "Secret of the Mimic" mechanics. The first thing you need to master is the augmented reality interface. Unlike the V.A.N.N.I. mask from Ruin, this early prototype tech is glitchy. It flickers.
The initial rooms serve as a tutorial for the "Echo" system. You'll find yourself staring at a locked door with no keycard. To pass, you have to find a recording device—basically a primitive version of the Mimic’s learning software—and play back the sound of a manager’s voice to the biometric scanner. It’s a clever nod to how the Mimic eventually becomes a master of deception.
Walk slowly. I can't stress this enough. The flooring in the assembly wing is metal grating, and if you sprint, the sound carries. There's something in the vents. It’s not the Mimic yet—at least not in its full form—but the prototype endoskeletons are sensitive to vibrations. If you see a yellow light blinking in a vent, stop moving. Just wait.
Navigating the Assembly Line and the Mimic’s First Appearance
Once you reach the assembly line, the fnaf secret of the mimic walkthrough hits its first real spike in difficulty. This is where you encounter the "Jackie" animatronic—or at least the terrifying, jester-like precursor to what we've seen in teaser trailers.

This section requires intense timing. You have to navigate a conveyor belt system while ducking behind half-finished chassis. The Jackie entity moves in a stop-motion fashion. When the overhead lights flicker, it moves. When they are solid, it stays still. It’s essentially a high-stakes game of Red Light, Green Light, but if you lose, you get stuffed into a shipping crate.
The Power Grid Puzzle
You’ll eventually hit a dead end at the main power hub. To progress, you need to reroute three power cells.
- Cell 1: Located in the basement crawlspace. You’ll have to distract a lone endoskeleton by throwing a decoy (look for the "Faz-Rations" cans on the floor).
- Cell 2: Tucked away in the upper observation deck. This requires a bit of platforming. Jump across the hanging cranes, but watch the sway. If you fall, you’re back at the start of the wing.
- Cell 3: This one is the kicker. It’s inside a glass containment unit that is currently being "inspected" by a prototype Mimic.
To get the third cell, you have to use the environment. There’s a steam valve nearby. Hissing steam obscures the Mimic’s sensors, giving you a five-second window to grab the cell and bolt. Don't look back. Just run toward the elevator.
Understanding the Mimic's AI
Here is the thing about this game: the AI is actually learning. If you hide in the same locker twice, the Mimic will check it the third time. If you always turn left when panicked, it starts flanking you from the left. This is a massive shift for the franchise. It’s not about memorizing a path; it’s about breaking your own patterns.

Real experts in the community, like the folks over at Technical FNAF, have noted that the Mimic’s pathing isn't scripted like the animatronics in Security Breach. It uses a heat-map system based on your noise and light usage. Basically, keep your flashlight off unless you absolutely need it. The grainy 1970s lighting is your friend, even if it’s terrifying.
The Secret of the Mimic: Reaching the Core
The final stretch of the game takes place in the "Sub-Level 4 Research Lab." This is where the lore gets heavy. You’ll find documents signed by Edwin Murray, and if you’ve read the Tales from the Pizzaplex books, you know exactly how tragic this is.
In this area, the Mimic is no longer just a scrap-metal endoskeleton. It has started "wearing" parts of other machines. It’s faster, louder, and much more aggressive. The walkthrough for this final chase is simple in theory but brutal in practice:
- Seal the Vents: There are four manual levers spread across the lab. You have to pull them while the Mimic is hunting you.
- Overload the System: Once the vents are sealed, head to the central terminal. You’ll need to input a code found on a sticky note in the breakroom (it’s randomized for every playthrough, so check your screenshots).
- The Final Stand: You have to hold your ground at the terminal for 60 seconds while the Mimic tries to break through the reinforced glass.
During this minute, don't just stare at the Mimic. Look for the "Safety Override" buttons that pop up on the monitors. Hitting these triggers a localized shock that stuns the creature. If you miss more than two, the glass breaks, and it's game over.
Misconceptions About the Ending
A lot of people think there is only one ending to the fnaf secret of the mimic walkthrough, but that’s not true. Depending on whether you collected all the "Memory Orbs"—small, glowing glitches found in the AR world—the final cutscene changes significantly.
If you get them all, you see a glimpse of the 1979 incident that led to the facility being shuttered. It confirms that the Mimic wasn't originally evil; it was a toy designed to mimic a child’s play, which became twisted after a series of violent events. It's a nuance that many players miss because they are too busy running for their lives.
Actionable Strategy for Your Next Run
To actually beat this game without a dozen restarts, you need a different mindset than the previous titles. Forget the cameras. Forget the doors. This is a game of stealth and psychological management.
- Listen for the Hydraulic Hiss: The Mimic’s joints are old. Before it enters a room, you will hear a faint hiss-click. That is your cue to drop into a crouch and hide behind the nearest heavy object.
- Manage Your Battery: Your AR device consumes battery fast. Only use it to find quest items. If you run out in the final lab, you won’t be able to see the "Safety Override" buttons.
- Distraction is King: Use the environment. If there is a radio, turn it on and run the other way. The Mimic prioritizes sound over sight for the first half of the game.
- Stay Out of the Light: High-contrast areas are death traps. The Mimic sees movement much better in well-lit corridors. Stick to the shadows.
The mystery of how a 1970s AI ended up buried under a Pizzaplex decades later is finally coming into focus. By following this fnaf secret of the mimic walkthrough, you’ll not only survive the night but also piece together the most important origin story in the Five Nights at Freddy's universe.
Keep your eyes on the vents. Watch for the twitching limbs. And whatever you do, don't let it learn your name.
Next Steps for Players:
- Locate all 12 Memory Orbs in the first three wings to unlock the "Legacy" ending.
- Map out the randomized keypad codes in the breakroom to shave minutes off your speedrun.
- Pay close attention to the background posters; they contain the dates for the upcoming DLC chapters.
