Kao Corporation: Silent Cleaning
Kao Corporation sought to increase brand awareness and relevance among Gen Z consumers who were disengaged from traditional home care advertising. The client tasked Whatever Co. with finding a way to make cleaning a trending topic. The objective was to shift perceptions of housework from a chore to a satisfying activity, ultimately driving product trial and sales among a younger, digital-native audience.
Creative Idea
Players must clean silently to survive a horror game, making chores feel life-threatening.
Kao transformed mundane household chores into a high-stakes horror game, forcing players to clean silently to avoid monsters. By gamifying cleaning, they turned a boring, un-trendable topic into viral entertainment that drove massive product engagement among Gen Z.
Turning Household Chores Into Survival Horror
Engineering The Sound Of Clean
To ensure the game felt authentic, the team utilized Foley sound recording to capture the precise, satisfying acoustics of Kao products. Every hiss of the Magiclean EXPOWER Limescale Spray and the distinct squeak of Quickle mops were recorded in high fidelity. This sensory attention to detail was critical, as the core game mechanic relied on sound: players had to clean surfaces without making enough noise to alert the blind, sentient grime monsters stalking the villa.
Viral Mechanics And Streaming Freedom
The campaign’s success was anchored in a permission-free streaming model. By allowing creators to monetize their playthroughs without fear of copyright strikes, the agency turned the game into a massive organic content engine. The collaboration with veteran streamer Gatchman served as the catalyst, triggering a wave of influencer engagement that propelled the title to #1 on Steam’s Free Game ranking and the top of the X trending list on launch day.
From Digital Scrubbing To Retail Sales
The gameplay loop cleverly mimicked item-crafting tropes found in classic survival horror, such as combining wet wipes with mop handles to reach tight corners. This gamification of chores had a direct impact on commerce. Streamers frequently adopted a "home-shopping" persona while playing, reading product descriptions to their audiences. This behavior drove a doubling of sales for the featured cleaning products, proving that Gen Z audiences would engage with household brands if the medium provided genuine entertainment value. The project was completed in a rigorous 8-month development cycle, utilizing a strict technical framework managed by BASSDRUM to ensure seamless asset integration between 3D artists and Unity engineers.
