Stuck in the decaying nightmare of Lucky Dart’s retro survival horror FPS? The exact puzzle solutions Comatose requires to progress involve tracking Rusty through the dark, digging the correct grave dirt mounds, navigating the bookshelf maze in House 36 for the Serpent Key, and triggering the Handprint Button after examining the Pigface mask. Because the game's June 2026 Early Access patch completely removed the confusing combination padlocks and replaced them with fixed keys, older video guides are already obsolete. This comprehensive walkthrough covers the updated, exact steps you need to survive the grimy prison corridors and escape your own mind.
Released into Early Access by publisher The Bueno Interactive, Comatose is a love letter to early Resident Evil and Silent Hill, injected with a dose of modern survival grit. You are trapped in a comatose state, forced to manage scarce resources and fight psychological manifestations like tyre-freaks and pig-monsters. But while the combat is punishing, it is the cryptic progression blockers that are leaving players stranded. Here is exactly how to bypass them.
Why the Puzzle Solutions Comatose Throws at You Are So Unforgiving
The fundamental challenge of Comatose lies in its shifting mechanics. The game's setting—a literal decaying mind—means that environments are intentionally disorienting. Fixed-feeling spaces, deliberate fight-or-flight combat, and lighting that actually matters all combine to create an atmosphere where missing a single key item means certain death.
However, the biggest hurdle for new players is the discrepancy between launch-day guides and the current state of the game. Lucky Dart’s June 2026 patch completely overhauled the game's logic. The developer stripped out the notorious combination padlocks entirely, replacing them with fixed keys because the original mechanic was deemed too confusing. The patch also implemented a 20% health nerf to the first boss, fixed the grave dirt models so all sites are diggable, corrected a bug where Eunice’s dialog was spoken by Laura, and addressed the frustrating Noia respawn glitch near the Serpent Key.

| Grave Dirt | Only select mounds were diggable | All grave dirt sites are now diggable |
| First Boss | Full health pool | Health nerfed by 20% for balance |
| Handprint Button | Could disappear upon entering/exiting | Persists correctly in the environment |
| Rusty Quest | Continuity error allowed retriggering | Triggers only once per playthrough |
Early-Game Puzzle Solutions Comatose: The Grave Dirt and Rusty’s Trail
The opening hours of Comatose establish the game's brutal reliance on light and observation. You awaken with nothing, surrounded by distressing ambient sounds and thick fog.
Your first major progression block involves navigating the dark sections of the map. You will start with a simple lighter before eventually securing the flashlight. Do not attempt to cross the dark section without the lighter equipped; the game will physically block your path. Once illuminated, you must follow Rusty's trail past the first row of headstones.

In the graveyard area, you will encounter multiple mounds of dirt. Previously, players wasted hours trying to figure out which specific models were interactive. Thanks to the recent update, every grave dirt site is now diggable. You need to systematically dig the mounds near the back fence. Inside the third mound from the left, you will unearth the rusted iron key that replaces the old padlock. Use this key on the iron gate to exit the graveyard and proceed toward the residential sector.
Mid-Game Puzzle Solutions Comatose: House 36 and the Serpent Key
The mid-game shifts from outdoor fog to claustrophobic indoor environments. Your primary objective here is to locate and infiltrate House 36—affectionately dubbed the bookshelf house by the community.
The entrance to House 36 has been made much more visible in recent patches, but navigating its interior remains a labyrinthine nightmare. The house is a literal maze constructed from towering, rotting bookshelves.
Infographic detailing the mid-game puzzle solutions Comatose players need to navigate House 36.
To solve the House 36 maze, follow this exact route:
- Enter the visible area: Step through the front door and immediately take a hard left. Do not walk toward the kitchen counters, as collisions have been added to prevent players (and enemies) from vaulting them.
- Avoid the Noia respawn: Previously, the enemy known as Noia would instantly respawn if you left and re-entered this house. While this is fixed, Noia still patrols the central hallway. Bait Noia into the living room, then sprint around the central bookshelf pillar.
- Listen for Eunice's voice line: As you approach the back bedroom, an audio cue will play. Ensure it is Eunice speaking (not Laura, as the old bug dictated). This voice line triggers the unlocking of the bedside drawer.
- Collect the Serpent Key: Open the drawer to claim the Serpent Key.
With the Serpent Key in your inventory, you can unlock the heavy rusted door at the end of the street, transitioning from the residential nightmare into the grimy prison corridors.
Late-Game Puzzle Solutions Comatose: The Handprint Button and Pigface Mask
The prison sector is where Comatose leans heavily into its Silent Hill inspirations. The corridors are rusted, blood-stained, and patrolled by the terrifying pig-monsters.
The core puzzle in this area revolves around a strange, ritualistic shrine. You will find a bloody Pigface mask resting on a pedestal in the center of a cell block.

Here is the exact sequence to solve the Pigface puzzle:
- Approach the pedestal: Interact with the mask. A brief, unsettling cinematic will play, flashing images of the protagonist's trauma.
- Verify the mask is gone: After the cinematic, the game will state that the Pigface mask is gone. (Note: A previous bug allowed players to infinitely interact with the empty pedestal, triggering looping dialog. This has been patched out; the pedestal is now inert).
- Locate the handprint button: Turn exactly 180 degrees from the pedestal. Walk to the far wall of the cell block. Hidden in the grime is a bloody handprint button. Press it.
- Proceed to the boss: Pressing the button triggers a loud mechanical grinding noise. The path to the first boss unlocks at the end of the cell block.
Combat, Boss Fights, and Resource Management
Solving puzzles is only half the battle in Comatose; surviving the spaces between them is the real test. The game utilizes a defend mechanic that allows you to mitigate incoming damage, but beware: you still take chip damage when blocking. Furthermore, in tight spaces—like when a tyre-freak enters a small hospital room—dodging is physically impossible. You must rely on spatial awareness and preemptive strikes.
Before you step through the door unlocked by the handprint button, scour the immediate area. The developers have deliberately placed several handgun ammo pieces in the region right before the first boss. These items were previously bugged and non-interactable, but they are now fully functioning and entirely necessary.
The first boss is a towering, grotesque manifestation of guilt. Do not waste your limited stamina trying to outrun it in the small arena. Instead, create distance, utilize the handgun ammo you just collected, and aim for the fleshy weak points exposed after it finishes a charge attack. Thanks to the recent balance patch, the boss has had its health nerfed by 20%, making this encounter a test of resource management rather than an unfair war of attrition.
Frequently Asked Questions About Comatose
Did they remove the combination padlock in Comatose? Yes. While early versions of the game featured a frustrating combination padlock (which was briefly patched to work on 5-increments), the developer completely removed it in the June 2026 update. It has been replaced by standard rusted iron keys found in the environment.
Where is the Serpent Key located? The Serpent Key is located inside House 36 (the bookshelf house). You must navigate the bookshelf maze, bypass the enemy Noia, and listen for Eunice's specific voice line to unlock the bedside drawer containing the key.
How do I beat the first boss in Comatose? Conserve the handgun ammo found in the prison corridors immediately preceding the boss arena. Keep your distance, let the boss execute its charge attack, and fire at its exposed weak points. The boss's health was recently nerfed by 20%, making the fight significantly more manageable.
Why does the "Follow Rusty" quest keep retriggering? If the quest to follow Rusty triggers multiple times in the same area, you are playing on an outdated build of the game. This was a known continuity error that has been patched out. Update your game on Steam to resolve the issue.
