The iconic first-person shooter game DOOM has been revamped into a Captcha test, challenging users to gun down three enemies to prove their humanity. The WebAssembly application is a fitting tribute to the original 1993 game, showcasing the power of modern technology.
To verify their identity, developers have come up with an unconventional method: playing a simplified version of DOOM. Players must navigate through levels, shooting bad guys and avoiding death. However, if they’re killed before achieving three kills, they’ll have to start over.
The Captcha is designed for the masses, making it accessible to gamers of all skill levels. Even those who don’t know what a traffic lamp is can try their hand at this novelty test. Interestingly, enabling God Mode and giving oneself unlimited weapons requires more than three kills to pass.
This unique approach highlights the advancements in technology over the past 30 years. The Captcha’s reliance on image classification and machine learning is reminiscent of the early days of OCR (Optical Character Recognition) technology.
While some appreciate the novelty, others find it tedious. However, this test could be a valuable tool for verifying user identity, especially in areas where traditional Captchas might not work effectively.
