Secret Lab Cleaner Demo is a free adventure game developed by FUN OVER GAMES. It is a demo version that includes a tutorial stage and one full office level. In this game, you step into the shoes of a janitor on his first shift in a shadowy underground facility — but this is no ordinary cleaning job.

One shift to survive

Secret Lab Cleaner Demo drops you into a surreal, creepy scenario: you play as a janitor on your first day working in a secret underground facility — and your job quickly becomes a fight for survival. Guided by a childlike, unsettling AI assistant named ANNA, you’ll perform various tasks, but be aware of the immortal entities that lurk.

This demo includes one full office level and a tutorial, and even in that short slice of content, you navigate horror, gore, and the constant fear of death while trying to finish the shift. However, take note that the horror and gore are intense, which may not appeal to all players.
