Knock Knock: Room Defense

Knock Knock: Room Defense is a horror-themed defense game featuring RPG elements and idle mechanics. A peaceful city has rapidly transformed into a hunting ground for countless terrifying ghosts and monsters. The game evokes the dread once inspired by animatronic bears in an entertainment center.

Description

When you hear "knock-knock"—a rap at the door—terror draws closer. Your objective is to lock the door and work with your heroes to defend the room. You choose a location (such as a school, hospital, hotel, or office, alongside unique settings like a train, dormitory, or underground cave), lock the door, and turn the space into a fortress. As you establish a solid line of defense right inside your room, the action evolves into a thrilling game of hide-and-seek. The game's pacing allows you to jump into the action anytime, anywhere. Players can easily summon powerful heroes to drive back the dark forces lurking outside the door.
