Some jobs are tough.
Some jobs are disgusting.
And then there’s Secret Lab Cleaner — a game where mopping floors is the least horrifying part of your shift.

You play as a newly hired janitor in a classified underground research facility, guided by ANNA, an AI with an unsettling, childlike voice. Your mission seems simple at first: clean biological waste, scrub anomalous messes, and keep the facility in order.

But the deeper you move into the complex, the more obvious it becomes that something is very wrong. This is a place where anomalies roam, entities stalk the hallways, and nothing stays normal for long.

Your First Day on the Job

From the moment your shift begins, the sense of dread is unmistakable.
Missing staff.
Half-written reports.
Silence stretching across entire divisions of the lab.

ANNA’s calm voice guides you through each task, but her emotionless instructions only make the situation feel more dangerous. Every assignment becomes a test of nerves as you try to stay alive in a facility that seems determined to kill you.

You will need to:

  • Clean hazardous biological materials
  • Navigate secure zones where anomalies have broken containment
  • Avoid entities that cannot be stopped
  • Follow ANNA’s protocols precisely or risk severe consequences

Even the simplest cleaning duty can become a life-threatening situation when something is breathing just out of sight.

ANNA: Helpful, Harmless, or Something Else

ANNA’s childlike tone contrasts sharply with the horrors she calmly explains.
She sees everything.
She controls the doors.
She monitors every mistake.

Her guidance is essential, but her intentions are constantly in question. Sometimes she sounds protective. Other times, she sounds like she’s waiting for you to fail.

Cleaning as Survival

Secret Lab Cleaner blends first-person horror with tense environmental puzzles and stealth-based survival. Every corridor demands caution, and every puddle of unknown material requires a deep breath before you get close.

By turning ordinary janitorial tasks into high-pressure moments, the game creates a uniquely unsettling experience. There are no weapons, no heroics — only a mop, a flashlight, and the constant fear of what’s lurking beyond your peripheral vision.

Why It Stands Out

Horror games often rely on combat or chase sequences, but Secret Lab Cleaner succeeds through tension, atmosphere, and vulnerability. It shares DNA with SCP-inspired projects, containment breach scenarios, and AI-driven psychological horror, but it brings a fresh perspective by focusing on the lowest position in the facility hierarchy: the janitor.

If you enjoy slow-burn horror, unnerving environments, and the feeling of being completely unprepared for what you’re about to face, this is a game worth watching.
