Doomsday Landlord is a unique strategy game set in a post-apocalyptic environment where players take on the role of a landlord managing an apartment building filled with survivors. The main objective is to house these characters, assign them rooms, and ensure they produce and consume items while paying rent daily. Players can build, expand, or tear down sections of their base and merge rooms to enhance their overall star rank, creating a dynamic living space.

The gameplay is structured around a series of Survival Plans where players must collect drumsticks and meet specific goals within a limited timeframe. As the game progresses, players face various challenges, including infections, invasions, and zombie threats, all of which require careful monitoring of safety and survivor well-being. With permanent resources like Survival Coins for character upgrades and a talent tree for enhancing abilities, Doomsday Landlord combines strategic management with humor and absurdity.
