Final Nights 4: Fates Entwined is the fourth and final entry in JeliLiam's Final Nights saga, and widely considered the best of the series. Powered by Unreal Engine 4, this game splits its gameplay between two timelines: classic FNAF camera-based nights as Henry Stillwater in 1973, and point-and-click investigation sections as detective Max Donovan in 2017. It's the first game in the series to abandon the FNAF 4-style formula, introducing unique mechanics for each animatronic, puzzle-solving exploration, and a story about intertwined fates that ties the entire saga together. With multiple endings determined by your knowledge of the lore, Final Nights 4 rewards paying attention.
The first three Final Nights games were heavily inspired by FNAF 4's bedroom-defense formula. Final Nights 4 throws all of that out. Instead of listening for breathing at doorways, you're working with a full camera system, alarm buttons, ventilation controls, and animatronics that each demand a completely different defensive strategy. It's the leap the series needed — and by far its most ambitious entry.
But the night shifts are only half the game. Between each night, you step into the shoes of Max Donovan, a paranormal investigator who's spent over five years digging into the mysteries of Freddy Fazbear's Pizza. These point-and-click sections have you exploring abandoned locations from previous Final Nights games, solving puzzles, surviving chase sequences, and uncovering the truth about what happened at Fredbear's Family Diner. You carry a notebook that tracks your investigation questions and a backpack for collecting key items.
The dual-timeline structure gives the game a narrative depth that most FNAF fan games don't attempt. What you learn as Max in 2017 recontextualizes what you experience as Henry in 1973, and the game's ending system is built entirely around whether you've been paying attention to the lore.
Final Nights 4 Gameplay
Night Mechanics
Each animatronic in Final Nights 4 has its own unique behavior and requires a different strategy to survive. The nights take place in Fredbear's Family Diner, where you monitor cameras, trigger alarms, and manage ventilation:
Fredbear: The most complex threat. He roams the restaurant turning off lights. You need to guide him using camera alarms toward the party rooms, then lure him into the hallway with the office alarm. He appears 2-3 times per night and should always be your top priority.
Spring Bonnie: Walks through the building toward your office. When you hear him approaching, stop everything and stare directly at him. He'll enter your office, look at you, and leave.
Puppet Master (Night 2+): Must be constantly monitored on cameras. Ignore him too long and he'll appear in Party Room 1 — either killing you or destroying your cameras.
Proto Spring Bonnie (Night 3+): Track him through cameras and spray gas when he stops moving. Be careful with the toxicity meter — if it's too high when he arrives, it's over.
Proto Fredbear (Night 4+): Enters through the ventilation system. Close the vent grate when he's in a specific pose. He can also appear in the hallway, where you need to stare him down.
Nights 1 through 4 are well-balanced and challenging without being unfair — each one adds a new animatronic while giving you time to learn their patterns before the next threat appears.
The Investigation and Story
Between nights, the investigation sections take you through locations fans of the series will recognize. You revisit the house from Final Nights 2, where dismantled animatronics — Foxy, Bonnie, Freddy, and Chica — need their souls freed using a hand crank while surviving chase sequences. You explore the abandoned Fredbear's pizzeria itself, where the Fredbear animatronic asks you questions about the lore that determine which ending you'll receive. And you venture into the hospital from Final Nights 3, navigating sewer puzzles and defending against Reaper variants of familiar characters.
The story centers on a dark truth: William Afton and Henry Stillwater co-founded Fredbear's Family Diner, but William created the "Insanity Disc" — a device using radio frequencies to cause hallucinations. When Henry rejected the idea, William tampered with the animatronics' AI and implanted the discs into Proto Fredbear and Proto Spring Bonnie, which killed Henry inside a Fredbear suit. His body remained sealed in the closed restaurant for 45 years. The subtitle "Fates Entwined" refers to the parallel destinies of William and Henry — both ending up alone, locked inside a springlock suit, consumed by fire.
What the Community Says
Final Nights 4 has earned strong praise as the standout entry in the saga:
One reviewer gave it a 7.5/10 — the highest score in the series — noting: "We're witnessing the first Final Nights that doesn't copy FNAF 4. It already earned 10 points right there." They highlighted that nights 1-4 have well-executed mechanics with fair difficulty, the investigation sections provide welcome variety, and the animatronic designs for Fredbear and Spring Bonnie are the best in the series. The extras museum was described as "one of the most beautiful I've seen in any fan game."
An English-speaking reviewer called it "the best story in the series" and "the most fair game out of them all — there weren't many game-breaking bugs and all the nights were pretty challenging while also not having me slamming my desk." They praised the point-and-click sections for still feeling like a FNAF game, and singled out the Insane Fredbear and Insane Spring Bonnie designs as "maybe my favorite designs in the whole series."
In broader FNAF fan game rankings, the entire Final Nights series has been called "genuinely legendary," with one reviewer describing FN4 as "one of the goats in the FNAF fan game space."
Frequently Asked Questions
Is Final Nights 4 free?
Yes, Final Nights 4: Fates Entwined is completely free to download and play on Windows PC.
Do I need to play the previous Final Nights games first?
It's recommended but not strictly required. FN4 revisits locations from Final Nights 2 and 3, and the story builds on the saga's lore. You'll get more out of it if you've played the earlier entries, but the game works as a standalone experience too.
The game won't launch on my PC. What do I do?
The original high-poly version has compatibility issues on modern systems (especially Windows 11). Make sure you're using the Low Spec version, which runs reliably on current hardware and also supports 32-bit systems.
How long does it take to beat?
A single playthrough takes roughly 1.5 to 2 hours. Getting both endings requires replaying the investigation sections with different answers to Fredbear's lore questions.
Is there an Android or Mac version?
No. Final Nights 4 is only available for Windows PC. There are no official ports for other platforms.
How do the multiple endings work?
During the investigation sections, the Fredbear animatronic asks you questions about the game's lore. Your answers determine which ending you receive. It's a system that rewards players who pay attention to the story rather than relying on arbitrary choices.
