Secret Lab Cleaner Demo for Windows

Quick summary

Secret Lab Cleaner Demo is a free, short-form survival-adventure created by FUN OVER GAMES. You play a janitor on their first shift inside a hidden underground research complex. The demo pairs mundane cleaning tasks with escalating dread as strange, immortal threats and unsettling situations emerge.

Setting and player role

You take on the role of a cleaning crew member thrown into a creepy subterranean facility on day one. A childlike but unnerving AI called ANNA provides guidance and commentary as ordinary chores become life-or-death decisions. The atmosphere blends surreal horror with bloodier moments, so tension and shock are constant companions.

Demo contents and features

• Includes one complete office-style level and a guided tutorial.
• Delivered as a free demo build from the developer FUN OVER GAMES.
• Delivers a brief, tightly focused survival experience rather than a long campaign.
• Mixes psychological dread with explicit gore and frequent danger from persistent enemies.

Warning and suitability

Because of its graphic scenes and intense scares, the demo may be unsuitable for viewers who are sensitive to gore, jump scares, or sustained anxiety. Players who prefer milder horror should approach with caution.

Alternative suggestion

If you want a longer or paid experience with similar high-tension mechanics, consider trying One Shift to Survive — a paid title that expands on the “one-shift” survival concept with additional content and systems.
