The skin stapler 100 percent walkthrough demands more than just finishing the story — it requires collecting every cassette tape, exhausting every dialogue tree, and completing each victim segment across all five chapters of this PSX grindhouse horror adventure. Released August 6, 2026 by Tainted Pact and published by Assemble Entertainment, the game has earned a Very Positive rating on Steam with 221 reviews, and the free demo (which hit 15,000 wishlists and a 92% positive rating) already teased how deep the investigation mechanics run. Because the game tracks completion at the save-file level, missing a single clue in Chapter 2 can lock you out of the true ending and the Completionist achievement permanently.
This the skin stapler game walkthrough guide breaks down every case, every hidden tape, and every branching choice in a spoiler-light structure, so you can chase that 100 percent save without ruining the horror for yourself. We will cover the full completion route, the murder cases walkthrough in order, the investigation walkthrough for every evidence piece, and the achievement path tied to each chapter. If you prefer to experience the story cold first, jump to the spoiler-free chapter walkthrough guide section — but if you are ready to see everything Carrion City hides, keep reading.
The Skin Stapler 100 Percent Walkthrough: Understanding Completion
A true 100 percent save in The Skin Stapler tracks three separate progress bars: evidence collected, cassette tapes found, and victim segments completed. The evidence bar fills as you examine crime scenes and piece together the killer's identity, while the tape collection spans hidden spots across all five chapters that most players miss on a first run because they are tucked behind environmental puzzles or optional dialogue triggers.
The game's PSX grindhouse aesthetic deliberately obscures some interactive objects — a stapled flesh pattern on a wall might look like set dressing when it is actually a clue you need to photograph. According to community reports from the Steam forums, several players finished Chapter 3 with only 60 percent of the evidence collected because they never returned to the Rusty Crane Docks after acquiring the UV flashlight. The completion route below accounts for these backtracking requirements.
100 Percent Walkthrough: Full Completion Route
The optimal route follows a simple rhythm: progress the main story until you unlock a new tool, then backtrack to previous areas before advancing further. The UV flashlight, the crowbar, and the wire cutter each open previously inaccessible paths, and the game never explicitly tells you to revisit old crime scenes.
| Objective | Where | Achievement Tie |
|---|---|---|
| Solve every case | Chapters 1-5 | Story achievements |
| Collect all tapes | Hidden spots | Tape collector achievement |
| Complete victim segments | Chapters 2-4 | Character achievements |
The Tape Collector achievement requires all 12 cassette tapes, and three of them are only reachable after you obtain the wire cutter in Chapter 4. Since the game auto-saves at checkpoint doors, you cannot reload an earlier chapter to grab a missed tape — you must either restart or finish the run and use chapter select (which the game unlocks after your first ending). Because of this, the the skin stapler full playthrough route below treats Chapter 4 as the point of no return for exploration.
Murder Cases Walkthrough in Order
Each chapter presents a distinct murder case that connects to the overarching Skin Stapler investigation, and the order matters because evidence from earlier cases unlocks dialogue options in later interrogations. The Butcher of Hollow Street case in Chapter 1 introduces the staple-pattern signature, while the Dockside Flayer case in Chapter 3 reveals the killer's counting rhyme that becomes crucial for the Chapter 5 finale puzzle.
Murder Cases Walkthrough in Order
The five cases follow a chronological investigation arc, with each one building on the previous discovery. Chapter 1 focuses on the initial crime scene and teaches you the photograph-and-compare mechanic, while Chapter 2 shifts to a victim survival segment where you play as a trapped victim trying to escape before the killer returns.
| Chapter | Completion Tasks | Missable |
|---|---|---|
| Chapter 1 | All evidence + tape | No |
| Chapters 2-4 | Victim actions + tapes | Yes — some |
| Finale | Ending variant | Save before choice |
The missable content in Chapters 2 through 4 revolves around victim segments — brief playable sequences where you control the killer's targets. Each segment has optional actions (hiding under a bed, triggering a specific trap, finding a hidden note) that contribute to character-specific achievements. If you rush through these segments, you permanently miss those achievements on that save file, which is why the the skin stapler murder cases walkthrough recommends saving before each victim segment begins.
Investigation Walkthrough: Every Evidence Piece
The investigation walkthrough for every evidence piece requires a systematic approach to each crime scene, because the game's photograph-and-compare mechanic means you must capture the right angles to trigger clue synthesis. Simply examining an object is not enough — you need to photograph it from the position indicated by the camera icon prompt, and some prompts only appear after you have examined other objects in a specific order.
Investigation Walkthrough: Every Evidence Piece
The evidence system tracks primary clues (required to advance the case) and secondary clues (optional but contribute to the completion percentage). Primary clues are always marked with a glowing outline, while secondary clues require you to interact with environmental objects that look like background dressing. The stapled flesh patterns on walls, for example, are secondary clues in every chapter — photograph all of them to unlock the Forensic Eye achievement.
According to player testing documented in the full game walkthrough by AlbearGames, the evidence counter in the pause menu updates in real time, so you can verify whether you have missed anything before leaving a crime scene. The counter displays as a fraction (for example, 8/10 evidence found), and if you leave a scene with an incomplete count, you will need to backtrack later. Because some crime scenes become inaccessible after story progression, always check the counter before advancing through a story door.
The Chapter 2 apartment crime scene is the most commonly missed evidence location — the bathroom mirror hides a fingerprint that only appears after you flush the toilet three times. This obscure interaction was discovered by community members experimenting with environmental objects, and it is not hinted at anywhere in the game's UI. The the skin stapler investigation walkthrough community has documented several such hidden interactions, so checking forums after each chapter is a smart habit if you want to avoid replaying the entire game.
Spoiler-Free Chapter Walkthrough Guide
This spoiler-free chapter walkthrough guide covers the structural flow of each chapter without revealing story beats or killer identity. The goal is to help you understand what to expect mechanically so you can plan your completion route, while still preserving the narrative surprises that make the game memorable.
Spoiler-Free Chapter Walkthrough Guide
Chapter 1 introduces the core loop: arrive at a crime scene, photograph evidence, interview witnesses, and confront a suspect. It is entirely linear, with no missable content, making it the perfect tutorial for the game's investigation mechanics. The chapter ends with a choice between two suspects, and while both options lead to the same next chapter, the dialogue you unlock affects later interrogation options.
Chapters 2 through 4 follow a alternating structure: investigation segments (playing as detective Dick Slater) and victim segments (playing as the killer's targets). The victim segments are where missable content lives, so save before each one. Chapter 3 introduces the UV flashlight, which immediately opens backtracking opportunities in Chapters 1 and 2 — this is when you should sweep previous areas for hidden tapes and secondary clues.
Chapter 5 is the finale, and it contains the ending variant that determines whether you get the true ending or the standard ending. The game warns you before the point of no return, but the warning is easy to miss if you are not reading carefully. Save before entering the final area, because the ending choice is not reversible without reloading.

Full Playthrough Path for All Achievements
The full playthrough path for all achievements requires at least two complete runs unless you follow the optimized route below. The first run should focus on story progression and victim segments, while the second run (using chapter select) cleans up any missed tapes and secondary evidence. Because chapter select only unlocks after your first ending, you cannot achieve 100 percent on a single blind playthrough.
Full Playthrough Path for All Achievements
The achievement list breaks into three categories: story achievements (unlocked automatically), collection achievements (tapes and evidence), and skill-based achievements (victim segment actions and stealth sections). The skill-based achievements are the most demanding because they require specific actions during tense sequences where the killer is actively hunting you.
| Order | Task | Reward |
|---|---|---|
| 1 | Follow main story | Chapters unlocked |
| 2 | Backtrack for tapes | Lore + achievements |
| 3 | 100 percent save | Completionist status |
The Completionist achievement requires a single save file to reach 100 percent across all three progress bars — you cannot combine progress from multiple saves. This means if you miss a tape in Chapter 2 on your first run, you must either restart the entire game or use chapter select to replay Chapter 2 and then continue through the remaining chapters on that same save. The chapter select system preserves your collected items, so replaying a chapter only adds new finds rather than resetting your progress.
For players who want to optimize their first run, the 100 percent guide covers the settings and difficulty options that make the stealth sections more forgiving, which is especially helpful for the Chapter 4 victim segment where the killer's patrol pattern is notoriously tight.
Chapter-by-Chapter Completion Checklist
This section provides a practical checklist you can follow chapter by chapter, ensuring you never miss a collectible or achievement trigger. The the skin stapler chapter walkthrough guide below assumes you are playing on Standard difficulty — the Nightmare difficulty removes the evidence counter, making completion tracking significantly harder.
Chapter 1: The Butcher of Hollow Street
Chapter 1 is the only chapter with zero missable content, which makes it the ideal place to practice the game's mechanics. Complete every dialogue option with both suspects before making your choice, because the interrogation notes you gather carry forward into Chapter 2's dialogue trees.
-
Photograph all primary evidence (marked with glow)
-
Find the hidden tape in the kitchen freezer (requires opening the freezer three times)
-
Exhaust all dialogue with both suspects
-
Make your suspect choice (either option is fine for completion)
Chapters 2-4: The Missable Content Zone
These chapters contain the bulk of missable content, so save before every victim segment and check the evidence counter before leaving each crime scene. The UV flashlight in Chapter 3 and the wire cutter in Chapter 4 unlock backtracking routes, so plan a sweep of Chapters 1 and 2 after acquiring each tool.
-
Complete all victim segment optional actions
-
Find all cassette tapes (3 per chapter)
-
Photograph all secondary evidence (stapled flesh patterns)
-
Check evidence counter before story doors
Chapter 5: The Finale
The finale has one missable element: the ending variant. Save before the point of no return, then experience both endings by reloading. The true ending requires specific evidence from earlier chapters, so if you followed the completion route above, you should have everything needed.
The Chapter 5 walkthrough guide provides a detailed breakdown of the final chapter's puzzle mechanics, including the counting rhyme sequence that determines which ending you unlock.
Frequently Asked Questions
How long does a 100 percent run take?
A full completion run typically takes 12 to 15 hours, depending on how quickly you solve the environmental puzzles and whether you need to backtrack for missed tapes. The first playthrough usually runs 8 to 10 hours, with the remaining time spent on chapter select cleanup and the second ending.
Can I get 100 percent on my first playthrough?
Yes, but only if you follow a guide from the start. The game does not warn you about missable content, so blind players almost always miss at least one tape or victim segment action. Using the the skin stapler 100 percent walkthrough above from Chapter 1 ensures you catch everything on a single save.
What happens when I reach 100 percent?
Reaching 100 percent on a save file unlocks the Completionist achievement and a special epilogue scene after the credits, revealing the skin stapler’s origin—a detail absent from all other playthroughs. This scene also confirms the true fate of Dr. Mercer, tying together every collectible and side objective you completed.
Does chapter select affect achievements?
Chapter select is safe for collection achievements, but skill-based achievements (victim segment actions) must be earned during the chapter's original context. Replaying a chapter through select does count for those achievements, but you must complete the full segment without dying.
Is the demo progress transferable?
No, demo progress doesn't carry over, but the opening chapters let you master the investigation loop before launch. For the full picture on what resets and what carries, check the single-player guide. The 100 percent walkthrough covers every tape and clue you'll need to re-find.
