We’ve all been there—trying to access a website, only to face the dreaded CAPTCHA. But what if, instead of matching obscured letters, ducks, or stairs, you could blast demons from hell? That’s the premise of Doom CAPTCHA, a new project that uses the classic first-person shooter Doom to prove a person isn’t a bot.
Doom CAPTCHA is the brainchild of software engineer and CEO of software developer Vercel, Guillermo Rauch, who shared a video of the project on X (formerly Twitter) on Tuesday.
“Verify you’re human by playing Doom and killing at least three enemies in nightmare mode,” Rauch said.
How does it work?
Using the arrow keys and space bar, players maneuver the ol’ space marine through the maze. Demons will spawn from all sides, and because you are in nightmare difficulty mode, they pack a harder punch.
