Endacopia Walkthrough: Prologue, Chapters I, II and III
Updated 2026-09-08 · Last verified 2026-09-08 · Steam Endacopia
Endacopia runs Prologue, Chapter I, Chapter II, Chapter III, and the fork that splits Ending A from Ending B sits in Chapter II, where you choose between a toy saw and a real saw and hand it to the Toilet Parasite. Everything before that fork is shared, and everything after it is documented only as an outcome, because no verified Chapter III walkthrough exists anywhere we could check.
Spoiler notice. This page names endings, boss outcomes and the secret area hidden in the Prologue.
Content warning. Steam's own description states the game "contains scenes of body horror, psychological horror, distressing imagery, blood, violence, death, drugs, and jump-scares". The Prologue secret described below is one of those moments.
Structure at a glance
| Segment | What it covers | Source depth | Can we give a route? |
|---|---|---|---|
| Prologue | Mellow's house: his room, the vents, the kitchen, the hallway, the restroom, plus the Underground | Best-documented segment on the community wiki, though the hallway and restroom sections there are empty headings | Yes, in broad strokes |
| Chapter I | The green place opens; all three main areas become available | A little over a thousand bytes on the community wiki, mostly a collapsed house sequence | Partially |
| Chapter II | Attic box, the saw, RODGER behind the mirror, hand the saw to the Toilet Parasite | Similar length, but the saw fork is confirmed five ways | Yes, for the fork |
| Chapter III | Ending A, Ending B and Ending C resolve here | Three bytes: "tba" | No |
Two navigation facts to fix first, because competing sites get them wrong. The hub area is called "the green place", which is the wording the community wiki uses in its own location fields, not "Green Hills". And Misery Town is a circus and carnival, full of clowns, a whack-a-clown stall and a Pierrot sideshow, not the "decaying suburban landscape" one fan site describes.
Prologue
The Prologue takes place entirely inside Mellow's house. Mellow, whose real name is Rodger Thompson, begins the game having lost his senses, which is Steam's own framing: he is "a young boy named Mellow who has lost all his senses in an attempt to escape an uncomfortable home". You recover them one area at a time later.
Controls are worth learning here rather than mid-fight. Movement is WASD with left click to interact, and right click cycles the action mode between view, touch and talk. That three-mode cycle is confirmed by both the community wiki's controls section and a games-media summary. It matters more than it sounds: at least one optional boss, Benjamin in Misery Town, only starts a fight if you interact using touch, and using talk instead is fatal.
| Prologue area | What is confirmed |
|---|---|
| Mellow's Room | Clockey is fought here. It is the one boss you cannot skip |
| The Vents | Connects the house; recorded as its own sub-area |
| The Kitchen | The Cheese comes from the fridge and lures a cockroach. Squashing the roach drops Two Quarters |
| The Hallway | Listed on the community wiki with no content written under it |
| The Restroom | Also listed with no content. The Plunger, which summons the Toilet, belongs to this thread of the game |
| Underground | Secret area. See below |
Those Two Quarters are not a throwaway. Feeding them to the Wall Bank produces a password, and the password is cheshire. It is the only password confirmed anywhere in Endacopia, it is corroborated by two separate community wiki pages plus outside guides, and it is the key to Ending C. Any other numeric code you see attached to this game, including a three-digit code for the Chapter II attic box, comes from a single fan site with a documented error record. We do not repeat those numbers. The myths page lists them and says where they came from.
The Underground secret
The Prologue hides a secret involving The Bride, and it does something almost no other game does: it deliberately crashes.
Triggering it throws what looks like a genuine engine error, naming room19.asc, line 16, and the crash carries a message in binary. This is recorded on the community wiki's Prologue page, and it is a single source, so treat the exact wording as unverified even though the existence of the crash is well described. The error text is formatted the way Adventure Game Studio reports errors, which is a reasonable read of the file extension and room naming, but no source states the engine outright and we are not going to assert it.
The deliberate crash is a repeated technique rather than a one-off. Skipping the AI boss in The Office, by filling the transparent mug with water and pouring it onto a socket, also crashes the game to desktop, and relaunching drops you past that section with the Short Circuit achievement. Two crashes on purpose, in two different parts of the game.
One disputed point belongs here. Some guide sites claim you must not fight Clockey during the Prologue if you want Ending C. The community wiki says the opposite in plain words: it does not matter whether you fight Clockey or not. There is no reliable consensus, so do not build a run around either claim.
Chapter I
Chapter I is where the game opens up, and it is also where the documentation thins out. The community wiki's Chapter I page is roughly 1,200 bytes and consists mostly of a collapsed sequence inside a house. The page for the closet redirects into it.
What is solidly confirmed is the shape rather than the steps. All three main areas are available and any of the three main bosses can be fought, in whatever order you like. That is not a fan inference: Steam's official feature list says "Decide which area to explore next in whichever order you'd like", and the community wiki's Chapter I page says any of the three main bosses can be fought. Two sources, one of them the developer.
| Area | Reached from the green place by | Final boss | Sense recovered |
|---|---|---|---|
| Misery Town | The ferris wheel | Trapezist | Mellow's hands |
| Timesville | Below the hub | The Chameleon | Mellow's eyes |
| The Office | The stone door and the train | The AI | Mellow's mouth |
The mouth is gated behind Genesis-01's "Let Me Talk". Each of those three bosses has a fight achievement and a skip achievement, and the six methods are documented in detail on the community wiki's achievements page rather than on any chapter page. Our bosses page collects them.
A useful scheduling note for Ending C runners: the hidden content in each of the three areas has to be completed before you beat that area's boss, so if you are aiming at Ending C, push each region up to its boss door and stop.
Chapter II
Chapter II contains the only branch in the game that changes your ending, and it is the best-sourced thing on this site.
You reach an attic and open a box after solving a puzzle. The community wiki says exactly that and gives no code. Inside, you get a saw. Behind a mirror in this chapter you can meet RODGER, a failed copy of Mellow who can be skipped entirely: run straight on after entering the mirror and you fall through a trapdoor towards Henry. There is also an optional boss here, Yew, reached by inserting Henry's floppy disk, logging in as Henry, opening the file called "aaaa" and clicking the crossed-swords icon. Yew cannot be fought in Chapter III.
Then the fork.
| Saw you take | Ending it leads to | Achievement | Global unlock rate, 8 Sep 2026 |
|---|---|---|---|
| Toy saw (fake) | Ending A | Escape | 40.0% |
| Real saw | Ending B | Return | 27.3% |
| Either, if you are running the secret route | Ending C | Stay | 14.3% |
Whichever you take, you carry it back and give it to the Toilet Parasite, and that is what opens Chapter III. This is confirmed across five sources: two self-consistent community wiki pages, the Steam Community all-endings guide, and two fan sites. One of those fan sites also claims you give the saw to "Roger". That is wrong. RODGER is the copy behind the mirror, not the recipient.
For an Ending C run, the community wiki states plainly that it does not matter which saw you pick, and one fan site agrees. A third site insists the toy saw is required. Two against one, with the more reliable pair on the "does not matter" side.
One more Ending C question has no clean answer: whether you need to finish Ending A and Ending B first. The community wiki doesn't list it as a requirement at all — its route starts from the Prologue with no mention of prior endings. The Steam Community all-endings guide calls the secret route "intended only if you have completed both Ending A and B," which is its own wording for a recommendation, not a requirement. A separate fan site states it as a flat rule. We are not settling this: treat "finish A and B first" as advice from one source, not as a gate the game enforces.
Chapter III, and why this page stops here
This is the honest part, and it is the reason this site exists.
There is no Chapter III walkthrough. Not here, and not anywhere we could verify. The community wiki's Chapter III page is three bytes long. Its entire contents are the letters "tba". The Office page on the same wiki is a stub of roughly 1,100 bytes, and Timesville is a stub too. The Steam Community all-endings guide, which is the best independent second source for this game and the one we lean on elsewhere, is written to be spoiler-light and does not walk the chapter. A major games site has a Chapter 3 page, but it is served behind a challenge page we could not read, so we will not cite steps from a summary snippet.
What we can state are the outcomes, and those come from the endings documentation rather than from any chapter page:
| Path | Confirmed sequence inside Chapter III | Confidence |
|---|---|---|
| Ending A (Escape) | Enter the door marked "Don't go in". Fight Henry by blocking on the side where a fleshy lump protrudes from the wall. Optional conversations. Turning off the lights triggers the ending | Route confirmed by the community wiki only. The lights trigger is single-source |
| Ending B (Return) | Enter the same door, pass through the sawn-open teeth, speak to the toilet creature, travel to Mellow's house, speak to the family, and tell his sister a bedtime story | Community wiki, with the bedtime story corroborated by a second summary |
| Ending C (Stay) | Use the plunger to reach the Toilet and enter cheshire. Later, re-encounter Clockey in Mellow's Room, crawl through the hole into The Surgeon's cave, read his books, sit down and ask him questions | Multiple self-consistent wiki pages plus outside guides |
In endings A and B, the enormous entity called God, inside whose body the game takes place, is established as having died in 2002 in "The Desert".
We are not going to fill the gap between those beats. A fan site with 35 pages already publishes its own three-chapter structure and stamps it "Verified": a grandfather-clock puzzle for Chapter 1, a boiler room and flooded basement for Chapter 2, and an electrical-grid repair called "The Ascent" for Chapter 3, plus four safe codes for a study, a pantry and a basement vault — rooms that do not exist in this game. None of it is real. Rooms invented, codes invented, an achievement invented that is not among the game's 16. That is what filling gaps looks like, and it is exactly what a search result rewards in the short term and destroys trust with in the long term.
So the record stops at "tba", and this page says so. If you have finished Chapter III and can document a route, the community wiki is where it belongs first. Until a route exists in a source we can point at, our endings page and the beginner guide carry everything that is actually known.
Update log
- 8 September 2026: Page created. Achievement unlock rates pulled from Steam's global stats on this date. Saw fork verified across five sources. The Chapter II attic-box code and the "give the saw to Roger" claim rejected as unsupported. Chapter III documented as an outcome list only, because the community wiki's page reads "tba" and no alternative walkthrough could be verified.
Frequently asked questions
How many chapters does Endacopia have?
Four segments of progression: a Prologue set in Mellow's house, then Chapter I, Chapter II and Chapter III. The three main areas of the game, Misery Town, Timesville and The Office, open during Chapter I and can be tackled in any order. That ordering freedom is stated in Steam's own store description and repeated on the community wiki's Chapter I page.
Is there a full Chapter III walkthrough for Endacopia?
Not one we could verify anywhere. The community wiki's Chapter III page contains the three letters 'tba' and nothing else, and no other source we checked documents a step-by-step route through it. What is confirmed is the outcome of each ending path once you are inside Chapter III, which is drawn from the Endings page rather than from a chapter walkthrough. We will not reconstruct the rest.
Which saw should I take in Chapter II?
The toy saw leads to Ending A (the Escape achievement) and the real saw leads to Ending B (the Return achievement). Either way you carry it back and give it to the Toilet Parasite, not to RODGER, to move into Chapter III. Five independent sources agree on this fork, which makes it the single best-confirmed mechanic in the whole game.
Do I need a code for the attic box in Chapter II?
No numeric code is documented by the community wiki, which only says to solve the puzzle and open the attic box. One competing fan site publishes a three-digit code for it, and a second site copies that site. Neither the game's own achievement data nor the community wiki supports it, so we do not repeat the number. The only password confirmed anywhere in Endacopia is cheshire.
Can I play Endacopia free in a browser?
No. Steam's own API lists Endacopia at $16.50 with windows true, mac false and linux false, which means a paid Windows download and nothing else. At least one fan site advertises a free browser version with a play button. That claim is false and there is no official web build.
Do I have to fight the bosses to finish Endacopia?
No. Every main boss except Clockey can be avoided, and each one has a paired achievement for skipping it: Cut The Act for the Trapezist, Case Closed for the Chameleon and Short Circuit for the AI. Steam's global stats as of 8 September 2026 show far more players fighting than skipping, but the community wiki states outright that combat is not a focus of the game.
