If you happened to find yourself with a new Roomba vacuum on your hands this holiday, you can use it to inject some demon-slaying into your home by turning it into a DOOM level.

The DOOMba, created by game engineer and programmer Rich Whitehouse, is designed to turn the sensors on one of the newer Roomba models, the Roomba 980, into real-life map-making tools that can inject some demon-slaying into your home.

Roombas already sense data about their environment as they go about cleaning. The DOOMba makes use of the little disc-shaped robot’s sensors and built-in simultaneous localization and mapping (SLAM) to turn your home into hell.

Whitehouse wrote in his blog about the project:

I soon realized that there was a clear opportunity to serve the Dark Lord by conceiving a plethora of unholy algorithms in service to one of the finest works ever created in his name. Simultaneously, I would be able to unleash a truly terrible pun to plague humankind.

When connected to a PC using imaging software like Whitehouse’s Noesis, that sensing data can be tracked and displayed as a graphic map, and ported into DOOM as a “wad,” or playable landscape. Once you have the map, Noesis gives you options for floor and ceiling textures and other game options.
