PAPERHEAD runs through 18 chapters plus one short interlude. The chapter names below come from the complete no-commentary full-game walkthrough published on YouTube at launch (fgw.gg), which documents the whole run with timestamped chapter cards. That run clocks roughly three and a half hours from the first chapter to the credits.
A note on what follows: no verified written source has documented per-chapter enemy rosters, boss mechanics, or secrets yet. Each entry below gives the chapter's verified name, its approximate length in the walkthrough, and what the chapter's position and title honestly suggest. Everything else is marked UNVERIFIED rather than guessed.
All 18 chapters in order
Chapter 1: The Descend (about 16 minutes)
The opening chapter. Sixteen minutes makes this a full introductory level, not a cutscene: expect the movement basics, the first combat encounters, and the first look inside the facility. The title matches the marketing's framing that the deeper you go, the worse things get. UNVERIFIED: the specific enemies and objectives in this chapter.
Chapter 2: Project G.E.P.P.E.T.T.O. (about 2 minutes)
At roughly two minutes, this reads as a story beat or transitional scene rather than a combat level. The dotted acronym is unexplained in every verified source we have. UNVERIFIED: what the project is and what happens in this scene.
Chapter 3: Object 808 (about 15 minutes)
A full-length chapter. The "Object" naming reads like a facility designation for something contained or studied on site. UNVERIFIED: what Object 808 is, which enemies appear, and the chapter objective.
Chapter 4: Let's Talk (about 3 to 4 minutes)
A short chapter whose title suggests a conversation or an encounter with a character rather than a firefight. UNVERIFIED: who does the talking and what is revealed.
Chapter 5: Subjectz (about 21 minutes)
The longest chapter of the early game. The name points to the facility's test subjects taking center stage here. UNVERIFIED: enemy types, any boss, and the chapter goal.
Chapter 6: The Shelter (about 4 minutes)
A short chapter by the clock. The name suggests a safe area or breather between harder sections. UNVERIFIED: whether it works as a hub and what the player can do there.
Chapter 7: Hunting Grounds (about 19 minutes)
A long combat-heavy stretch. The name points to an arena-style hunting section. UNVERIFIED: enemy waves and whether a boss closes the chapter.
Chapter 8: On the Way to...? (about 3 to 4 minutes)
A short transitional chapter. The trailing question mark is part of the official chapter card, not our punctuation. UNVERIFIED: the destination and what happens en route.
Chapter 9: The Farm (about 25 minutes)
The longest chapter in the game at roughly 25 minutes. A farm area inside a research facility suggests a major zone with its own enemy set. UNVERIFIED: area layout, boss, and any mechanics unique to this chapter.
Interlude: Critical Error (about 1 minute)
This one is not numbered as Chapter 10. The walkthrough labels it an Interlude, and the numbering jumps straight to Chapter 11 afterward. At one minute it is a transitional scene, and the name suggests a system-failure story beat. UNVERIFIED: the exact content of the scene.
Chapter 11: Depth Dweller (about 23 minutes)
A long chapter whose name suggests something that lives in the facility's depths. UNVERIFIED: whether the Dweller is a boss, an enemy type, or something else entirely.
Chapter 12: Broken Paper Man (about 9 minutes)
A mid-length chapter named for a specific entity. UNVERIFIED: who or what the Broken Paper Man is, and whether it is hostile.
Chapter 13: G.PRJ HQ (about 23 minutes)
A long chapter. The acronym reads as a project or organization headquarters inside the facility. UNVERIFIED: what G.PRJ stands for and what the area contains.
Chapter 14: New Project (about 3 minutes)
A short chapter whose title suggests a narrative turn, with a new project beginning late in the story. UNVERIFIED: the details of that turn.
Chapter 15: Vivisector (about 17 minutes)
A full-length chapter named for an entity or role. The word suggests something that cuts subjects open, which fits the game's horror framing. UNVERIFIED: whether the Vivisector is an enemy, a boss, or a story element.
Chapter 16: Rituals (about 8 minutes)
A shorter chapter whose name points to a scripted or ceremonial sequence. UNVERIFIED: what the rituals are and what the player does during them.
Chapter 17: Assault (about 17 to 18 minutes)
A long late-game combat chapter. The name signals an all-out attack sequence, likely the run-up to the finale. UNVERIFIED: enemy composition and any mid-chapter boss.
Chapter 18: The Manager (about 5 minutes)
The final chapter and the final boss of the game. Five minutes in the walkthrough suggests a single concentrated boss fight rather than a full level. UNVERIFIED: boss mechanics, phases, attack patterns, and any recommended loadout. We will not guess at a boss strategy.
How long is PAPERHEAD?
The documented full run takes about three and a half hours from Chapter 1 to the credits. Your own time will vary with difficulty setting, deaths, and how much you explore. Short chapters (2 to 4 minutes) are story beats; the long ones (15 to 25 minutes) are the full combat levels.
What is still UNVERIFIED
Boss tactics, enemy lists, per-chapter objectives, and collectible locations are UNVERIFIED at launch. TrueAchievements has no written walkthrough yet and thegamepost's hub still lists no guides. Any page claiming full chapter solutions right now is speculating. Bookmark this page and check back as facts get confirmed.
How to use this list
Use the chapter names to track your progress and to search for help on specific sections. The approximate lengths help you plan sessions: anything under five minutes is a breather, anything over fifteen is a full level. As chapter guides get written and verified, each name above will link to its own detailed walkthrough.
