Knock Knock: Room Defense is a horror-themed tower defense RPG where players barricade themselves inside haunted rooms and build defenses against waves of ghosts and monsters. Players upgrade doors, beds, heroes, and defensive structures during short matches, with different haunted locations such as schools, hospitals, hotels, trains, and underground areas serving as battle stages. The game mixes idle progression, hero collection, and strategic tower defense with a stylized chibi horror aesthetic.
Codes are sourced from the game's official Discord server, official Facebook page, official YouTube channel, and official website.
