Play The Cleaning Game, a Portal 2 Mod, on Steam: https://store.steampowered.com/…Cleaning_Game/">https://store.steampowered.com/…Cleaning_Game/
As a cleaning machine, tend to the custodial duties of an office while trying to avoid human scrutiny and existential dread. Listen to the computers around you, while there is still time. If you are brave enough, investigate your origin and inherent meaning as an electronic in a human world. The Cleaning Game is an independent, fan-made, total-conversion modification of Portal 2 © Valve 2011, which you are required to own a Steam copy of in order to play this game. However, The Cleaning Game takes place in a brand-new world built with fully custom assets crafted from the ground up.
