Mastering the Main Sequence in Level 01 The Basement

This segment provides a highly detailed roadmap for completing the mandatory objectives required to escape the starting area. Execute these specific actions to advance through the environment with precision.

Initiating the Broadcast

Your preliminary objective in this environment centers around the television. Navigate directly to the device and supply power to the unit by plugging it in. This action brings the monitor to life and permits you to analyze the active broadcasts.

Manipulating the Timeline

Immediately after the screen illuminates, direct your focus to the audio emitting from the active channels. The television commercials broadcast a covert audio hint regarding a specific time. Absorb that audio information, approach the clock mounted on the wall, and adjust the hands to display exactly 5:35.

The Door Defense Protocol

Right after you correctly calibrate the clock, a high stakes minigame commences. Loud banging noises will echo from behind two distinct doors. You will locate one door positioned near the staircase and the second door situated within the bedroom. These barriers will slowly begin to swing open. You must sprint between these locations and force the doors shut. Ensure you close them entirely before they manage to open all the way.

Managing Illumination and Muck

Midway through this defensive trial, the game aggressively ramps up the difficulty. The trial now introduces two light switches that demand your active management. You must maintain illumination in both rooms while simultaneously rushing to secure the violently banging doors. To monitor your remaining time, observe the surrounding walls. The volume of dark muck actively dripping down the walls serves as a visual timer for the challenge.

Activating the Optional Erased Switch

Following your successful completion of the door and light defense sequence, the game grants you access to the upper floor. Climb the stairs and search the resulting room to locate a specific wall switch. Toggle the switch found in this area. Keep in mind that this particular action remains completely optional. You only need to perform this step if you intend to secure the Erased achievement and witness the erased memory ending. The game requires you to toggle three total switches across your journey to secure this narrative conclusion, so activating this initial switch right now puts you on the correct path.

Escaping the Depths

To finally vacate the premises, seek out three distinct paintings that depict a vibrant waterpark. Fix your gaze directly onto any of these three canvases. Your specific choice of painting holds no weight because all three portals transport you to the exact same destination. You might feel tempted to run past them, but staring at these waterpark illustrations remains the sole method of progression. Maintain your visual focus on the canvas and you will successfully transition out of the zone. Congratulations on surviving the depths!

Securing the Man’s Best Friend Achievement

To claim the Man’s Best Friend achievement, the game mandates that you view every single variation of the animal photographs stationed in the basement.

The Photographic Evidence

Commence a fresh playthrough of the initial stage and walk straight toward the television set. Inspect the area immediately behind the television to discover a series of hidden photographs. You must repeatedly observe these images until the game displays every possible iteration.

The Eject Cycle

You do not need to play the level to completion to record your progress for this task. You simply need to eject your character from the active session and reload the environment. Players typically report that performing this reload cycle roughly five to six times successfully triggers the achievement.

Follow this exact sequence to guarantee your success:

1. Load your character into the basement level 1.
2. Activate the light source positioned nearest to the TV.
3. Observe the photographs tucked behind the TV.
4. Pause your session and select EJECT.
5. Load your character back into the basement level 1.
6. Activate the light source positioned nearest to the TV.
7. Observe the photographs tucked behind the TV.
8. Pause your session and select EJECT.
9. Load your character back into the basement level 1.
10. Activate the light source positioned nearest to the TV.
11. Observe the photographs tucked behind the TV.
12. Pause your session and select EJECT.
13. Load your character back into the basement level 1.
14. Activate the light source positioned nearest to the TV.
15. Observe the photographs tucked behind the TV.
16. Pause your session and select EJECT.
17. Load your character back into the basement level 1.
18. Activate the light source positioned nearest to the TV.
19. Observe the photographs tucked behind the TV.
20. Pause your session and select EJECT.
21. Load your character back into the basement level 1.
22. Activate the light source positioned nearest to the TV.
23. Observe the photographs tucked behind the TV.
24. Pause your session and select EJECT.

Continue executing this precise cycle until the notification pops on your display.

Unlocking the Saturday Showtimes Achievement

The Saturday Showtimes achievement serves as a test of sheer patience. The official task parameters require you to remain completely AFK for five whole minutes immediately after plugging in the TV in The Basement.

Couch Potato Status

As the parameters explicitly command, you must sit idle and observe the television broadcast after establishing its power connection. Maintain your focus on the screen for five unbroken minutes. It remains absolutely critical that you do not interact with your keyboard or your mouse during this entire duration. Even the slightest movement will disrupt the internal timer and force you to restart your attempt. Leave your hardware completely alone until the reward registers.

Conquering the Hide and Seek Achievement

To obtain the Hide and Seek achievement, you must actively hunt down both plushies hidden in The Basement.

Reaching Stage Two

You tackle this objective during your standard playthrough of the main sequence. After establishing power to the TV and adjusting the clock to 5:35, the defensive door minigame initiates. Proceed through the challenge as you normally would until the trial advances to the second stage. This specific stage forces you to maintain the room lights while continuously slamming the doors shut.

Armed and Ready

The moment stage two begins, monster plushies will commence spawning underneath the furniture stationed just past the doorway threshold. Equip your Nerf gun pistol and verify that it contains ammunition. As the doors slowly creep open, scan the floor beneath the tables for a hiding Monster Plushie. Upon spotting the target, discharge your Nerf gun to strike it. You might need to let the door open a fraction wider to secure an unobstructed firing line toward the toy. If a plushie fails to spawn, quickly shut the door and continue the trial.

You only need to land one successful shot on a plushie for both respective doors. This equates to two accurate shots in total. The achievement will immediately unlock the second you strike the final plushie.

Executing the Smile Attack Achievement

The Smile Attack achievement demands that you forcefully hurl a smile plushie into a second smile plushie.

A Different Approach

Much like the previous task, you must successfully adjust the clock and survive until the second stage of the door defense sequence. A plushie will predictably spawn beneath the furniture located just outside the room. Instead of firing your Nerf gun at the toy, you must adopt a hands on strategy.

Crouch down tightly against the door frame without physically crossing the threshold into the hallway. Press your E key to extend your reach and grab the plushie. If executed perfectly, your character will hold the toy. Drop the item safely inside your room near the door and resume your defensive duties.

The Collision Course

After you successfully snatch both plushies from their respective doorways, pick them both up. Throw the first plushie directly into the second plushie. The violent collision will cause both toys to instantly vanish, and your achievement will register immediately. Keep in mind that holding down the E key actively charges your throwing power, which adds significant velocity to the projectile.

Post-Challenge Combination

Exercise extreme caution to avoid bumping any foreign objects into your gathered plushies. The game engine interprets any physical bump as a direct hit, which triggers the vanishing effect and instantly ruins your current attempt.

To bypass this highly frustrating mechanic, you should purposefully kill your character the moment you secure the first plushie. When the environment resets, the plushie persists in the game world and waits in the exact spot you dropped it. This tactical death method massively boosts your odds of securing the second plushie without accidentally destroying the first one. Gather both toys safely and perform the collision throw only after you completely finish the door minigame.

Solving the Redacted Achievement

The Redacted achievement challenges you to spell a highly specific word using the mini fridge located in the environment.

Gathering the Alphabet

To conquer this task, you must arrange the letters to spell LILY on the appliance. Begin by scouring the immediate vicinity to gather all four loose alphabet fridge magnets.

Spelling the Secret

Once your inventory holds all four alphabet pieces, approach the appliance and stick the magnets directly onto the surface. Arrange the letters to correctly spell the word LILY. The magnets will immediately disappear from the metal surface, the overhead light in the room will extinguish, and your achievement notification will proudly display.

You must prioritize spelling the word LILY first. Refrain from spelling the word CALEB during this initial step. If you spell CALEB beforehand, the appliance door will swing open, which permanently prevents you from spelling LILY and locks you out of the achievement for that specific session.

Gathering the Two Hidden Collectibles

The environment contains exactly two tangible collectibles hidden within The Basement level. You will want to acquire both items during your exploration.

The Chilly Toy

Your first hidden item takes the form of a plushie securely locked inside the mini fridge. Begin by locating the scattered alphabet magnets positioned around the room. Collect them and apply them to the metal face of the appliance.

Manipulate the letter magnets to spell out the name CALEB. Upon entering the correct sequence, the appliance door will unlatch and open. Reach into the chilled interior to claim your very first collectible plushie. Make absolutely sure you only perform this action after successfully completing the Redacted achievement.

The Upstairs Literature

Your second item is a children’s book hidden on the upper floor. The game restricts access to this area until you conquer both rounds of the closing doors sequence. Finishing the defense trial unlocks the barrier and permits entry into the stairwell.

Climb the stairs and enter the room that houses the optional Erased ending switch. Closely inspect the drawer built into the furniture within this room. Pull the drawer open to expose the concealed item resting inside. Retrieve your collectible children’s book to definitively clear out the area.
