'Doom' Becomes a CAPTCHA Challenge for Proving Humanity

A new CAPTCHA requires users to play a modified version of the classic game 'Doom' to verify they are human.

Vercel CEO Guillermo Rauch developed a CAPTCHA that incorporates a playable version of the iconic 1993 first-person shooter 'Doom.'
To pass the CAPTCHA, users must kill three enemies on the game's 'Nightmare' difficulty using keyboard controls in a browser-based WebAssembly app.
The game is intended for educational and entertainment purposes, showcasing Vercel's AI site-building capabilities rather than being deployed widely for practical use.
This iteration builds on earlier Doom-themed CAPTCHAs, offering a more challenging and dynamic experience with faster gameplay and limited resources.
While the concept has generated buzz for its creativity, its effectiveness as a CAPTCHA tool is questioned, as AI bots could potentially be trained to complete the task.
