Chapter III Walkthrough

Chapter III is Endacopia’s final story chapter. What happens depends on the Chapter II saw choice (Toy Saw vs Real Saw → Roger) and whether you completed Stay prerequisites on a dedicated reload (Stay Secrets).

Update to patch 1.08+ before the epilogue. 1.07 adds title-screen Steam achievement sync for ending trophies that failed to register — load the title screen once if Escape/Return/Stay did not pop despite completing routes (Patch Notes).

Chapter III Routes Overview

Route	Saw given	Chapter III climax	Epilogue action
Escape	Toy Saw	Henry Boss uvula fight	Proceed through “please open” door → Family!
Return	Real Saw	Alternate confrontation	Proceed through main door → Family?
Stay	Either (after A+B)	Same boss beats as your saw path	Ignore door → return to Mellow’s Room

Full spoiler context: Endings Guide.

Escape Route — Henry Boss

If you gave Roger the Toy Saw, Chapter III includes the mandatory Henry boss fight:

1. Enter the mouth arena documented in Henry Boss
2. Bait Henry’s uvula with the correct timing loop (block M2 → counter M1)
3. Cannot skip — required for Escape achievement
4. After victory, reach the Chapter III epilogue house sequence

Save immediately before the arena. Combat deaths restart the fight only — exploration progress is kept.

Return Route

If you gave Roger the Real Saw, Chapter III plays a darker epilogue variant without the same Henry arena requirement documented on the Escape path. You still reach the ending house — Family? triggers when you follow the main epilogue door.

Plan a separate playthrough with a pre-Saw-Box save reload to experience both Escape and Return.

Stay Route — Epilogue Trigger

Stay is not a third saw choice — it is a Chapter III epilogue decision after completing all prerequisites:

Prerequisites (all required)

1. Escape and Return unlocked on prior playthroughs
2. Three area secrets complete on the same Stay attempt:
   • Misery Town cinema (Metal Detector)
   • Timesville 18-fish chain (Timesville Fishing)
   • Office telescope Morse (Telescope)
3. Fight every optional boss — no Cut The Act / Case Closed / Short Circuit skips (Optional Bosses)

Epilogue steps

1. Progress through Chapters II and III normally for your saw path
2. Reach the Chapter III epilogue “please open” door
3. Do not proceed through the door
4. Return to Mellow’s Room instead
5. If every secret was done correctly, the room changes — Stay / Family. plays

Patch 1.07 note: Re-entering Mellow’s room while the gold soccer ball ribbon is visible also triggers achievement sync for players who completed Stay but missed the Steam unlock.

The Yeti — Post-Story Cameo

The Yeti achievement is separate from the Escape / Return / Stay triangle. After seeing the main endings (community sources suggest after A+B+C), locate Andyland for the developer cameo and dancing mini-game.

Frequently Asked Questions

Q: Can I get Stay without fighting Henry on a Toy Saw run? A: Stay still follows your saw path’s Chapter III content — Toy Saw runs include the Henry fight. Stay’s unique trigger is the epilogue room return, not skipping Henry.

Q: What if Mellow’s room looks unchanged at the epilogue? A: A secret puzzle was missed or a boss was skipped. Reload your Chapter I save and verify Stay Secrets.

Q: My Stay achievement did not unlock — what now? A: Update to 1.07, load the title screen, then re-enter Mellow’s room with the gold soccer ribbon visible.
