DOOM runs inside Paint on Windows, built by a Microsoft executive: “The spreadsheet-tier framerate is part of the charm.”

Mark Russinovich, the Chief Technology Officer and Technical Fellow for Microsoft Azure, has unveiled a whimsical project that merges nostalgia with innovation. His latest endeavor, dubbed DoomPaint, allows the classic 1993 first-person shooter, DOOM, to run within the confines of Microsoft Paint. This unexpected crossover has sparked intrigue among both gaming enthusiasts and tech aficionados alike.

How It Works

While the term “playable” might be a stretch, Russinovich’s documentation on GitHub provides clarity on the mechanics behind DoomPaint. He notes, “Every frame is placed on the Windows clipboard and pasted into Paint’s canvas as a genuine document edit.” Essentially, Paint serves more as a display medium than a functional game engine. Users will need to install Python to run the application, although watching a demonstration video is also an option for those curious about this unique fusion.

A Creative Collaboration

This project stands out not only for its quirky nature but also for the collaborative effort behind it. The contributors section of DoomPaint reveals contributions from notable entities, including Anthropic’s Claude and Microsoft’s GitHub Copilot, suggesting a community-driven approach that resonates with the spirit of innovation.

The Humor Behind the Concept

Russinovich himself adds a layer of humor to the project, stating, “Paint renders the game but does not compute it. Paint computes nothing. Paint has never computed anything. That’s the joke.” This playful commentary underscores the lightheartedness of the endeavor, inviting users to appreciate the absurdity of running a game in a program primarily designed for simple graphics editing.

Sound and Music Integration

In a delightful twist, DoomPaint also features working sound and music, elevating the experience beyond mere visuals. However, Russinovich emphasizes that this remains a visual trick rather than a full-fledged engine conversion. For those familiar with the classic, acquiring a legitimate copy of DOOM’s internal “.WAD” file can enhance the experience, allowing players to explore a complete selection of levels and weapons.

For anyone yet to experience DOOM in 2026, DoomPaint offers a peculiar yet intriguing entry point into the iconic game, albeit one best appreciated from a distance. The project serves as a testament to the creativity and ingenuity that can emerge during moments of downtime, especially from a figure like Russinovich, who seamlessly blends his passions for retro gaming and classic Windows applications.
