Alyssa game walkthrough solutions guide you through every basement puzzle, mannequin chase, and stealth encounter across the mansion. Follow exact valve rotations, button sequences, book orders, and survival routes to evade captors and reach safety.
Basement Awakening and the First Valve Lock
After the opening cutscene in Cedar Grove where captors transport Alyssa into the estate, Emily unties Alyssa and opens the doorway leading into the lower chambers. Emily warns Alyssa to move quietly. Press J to open the journal to track objectives and notes. Crouch with Left Control to lower Alyssa's profile and proceed through the initial utility corridor.
Follow Emily until she spots the masked leader banging against an upper partition. Collect matches from the laundry shelves by pressing E. Emily separates from Alyssa once the pathway darkens. Light a match using F to illuminate surrounding doorways. The subsequent hallway introduces stationary wooden mannequins positioned around utility pipes.
To open the sealed gate in this workshop wing, locate the three colored valves attached to the wall pipes:
- Locate the green valve near the first mannequin grouping. Turn it first, corresponding to note scrap clues marking green as position one.
- Search the adjacent storage corridor for the blue valve. Turn the blue valve second to satisfy the intermediate sequence.
- Locate the yellow valve near the corner mannequin holding a cane. Turn the yellow valve third, as indicated by the numeral three on the associated scrap.
Turning the valves in the order of green, blue, and yellow unlocks the heavy iron gate leading toward the storage cells.
Mannequin Hallways and Wooden Block Puzzles
Past the valve gate, Alyssa encounters rooms stained with blood and biological remnants. Navigating this hall requires managing hostile mannequins that shift position whenever Alyssa breaks line of sight.
Keep your camera aimed directly at advancing mannequins while walking backward toward the hallway exit. If Alyssa turns around completely, the mannequins close distance instantly and trigger a lethal strike. Backstep through the narrow corridor until reaching the far chamber containing a locked metal door and a silver key resting on an altar pedestal. Collect the silver key, maintain visual contact on the two pursuers, and retreat through the low crawl space.
Inside the adjoining office, Alyssa must retrieve two carved blocks to open the security barrier:
- Collect the girl block resting on the shelf opposite the crawl exit.
- Examine the wall panel containing a grid of push buttons.
- Check the gathered scrap notes showing circle patterns numbered one through four.
- Input the sequence by pressing buttons in ascending numeric order (1, 2, 3, 4) to solve the buttons puzzle solution.
- Retrieve the boy block that drops from the wall mechanism.
- Insert both wooden blocks into the diamond receptacle beside the reinforced exit door to open the route toward the lower cellars.
Evading Evelyn and Finding the Four Fuses
The lower basement introduces Evelyn, a blind adversary stationed to guard the subterranean corridors. Evelyn cannot rely on sight, but she detects footsteps and loud environment interactions instantly. Walking on broken glass or slamming doors causes Evelyn to charge and strike Alyssa immediately.
To power the security gate mechanism leading upward, search the perimeter rooms for four electrical fuses while avoiding the guard.
| Threat Encounter | Behavioral Rule | Safe Countermeasure |
|---|---|---|
| Stalker Mannequins | Move rapidly when outside Alyssa's direct vision | Walk backward while keeping the camera centered on them |
| Evelyn the Guard | Completely blind; reacts instantly to loud sound and broken glass | Crouch-walk across carpet paths and avoid slamming doors |
| Blood Swamp Mannequins | Advance through sticky terrain where running is disabled | Light matches or stand near wall candles to freeze them in place |
Follow these steps to complete the generator circuit:
- Crouch immediately upon entering the central cage area. Track Evelyn's position by observing wall silhouettes cast by overhead hanging bulbs.
- Locate the first fuse sitting on a utility shelf along the left perimeter wall.
- Cross through the low air ducts to bypass Evelyn's patrol route and reach the locked maintenance storage.
- Use a lit match to locate the crowbar sitting inside the side utility alcove.
- Use the crowbar on boarded vents to reach the back corridor, where players can gather remaining items listed in the fuse locations breakdown.
- Insert all four fuses into the main fuse panel near the gate controls.
- Pull the primary switch to restore power to the stairs, reuniting Alyssa with Emily.
The Library Bookshelf Lock
Beyond the basement gate, Emily pauses due to physical exhaustion, forcing Alyssa to search ahead through an ornate library wing. The main exit door remains sealed behind a mechanical bookshelf displaying symbolic carvings: a sun, a star, an eye, a hand, and a moon.
Notes scattered across the study desks establish strict placement rules for the symbols:
- A torn diary entry states: "First the star, then the eye."
- A research note cautions: "The moon is never first."
- A sunrise sketch confirms: "The day always starts with the sun."
To unlock the secret passage, interact with the books on the shelf in this exact order:
- Sun
- Star
- Eye
- Moon
Entering this sequence disengages the mechanical lock and allows passage deeper into the mansion. For alternate symbol clues found on surrounding furniture, refer to the books puzzle solution.
Escaping Iris and Lowering the Trap
Past the library, Alyssa enters living quarters patrolled by Iris, the estate's maid. Iris wanders between narrow corridors reciting spoken lines while searching for escaped victims.
Iris uses an interior riddle to lock the hallway gates: "A smoker looks at the fire. A fool searches for treasure. A pig is afraid of the farmer."
To clear this puzzle:
- Rotate the smoker bust toward the flame painting.
- Rotate the fool dial toward the chest symbol.
- Turn the pig carving directly toward the axe-wielding farmer figure.
Solving the dials opens the service door, triggering a timed hide-and-seek sequence where Iris counts down from ten. Enter the storage coffin before the countdown ends.
Following a scripted capture scene where the captive Pigman intervenes to disrupt Iris's torture attempt, Emily provides a plan to escape the maid. Emily directs Alyssa to act as bait, drawing Iris directly beneath an overhead suspension rack. Lead Iris beneath the suspended crates and signal Emily, who drops the metal rod from the elevated control panel to eliminate the pursuer and secure the master elevator key.
Upper Floor Ritual and Story Endings
The master elevator carries Alyssa up into the residential chambers of the mansion. Here, Alyssa encounters high-profile political visitors awaiting ritual ceremonies conducted by Mortimer and the masked leader. Captors harvest adrenochrome from abducted children to fuel physical preservation and power a supernatural entity named Mulark.
Sneak through the dining salon while Mortimer searches the kitchen. Avoid floor debris and hide beneath banquet tables when Mortimer patrols the corridors calling out for dinner targets.
Collect kerosene containers and combustible books to trigger the mansion fire alarm system. Activating the fire controls separates the cultists and opens the inner sanctuary door where the ritual takes place.
Inside the inner sanctum, captors prepare the final blood offering. Disrupt the altar focus items before the summoning finishes. Depending on Alyssa's decisions regarding Emily, collected evidence, and actions during the final confrontations, the story branches into distinct conclusions detailed in the all endings summary. Escape through the ground-level courtyard exit to break free from the estate grounds.
