Proving you're human with a CAPTCHA test has never been more fun.

Frontend development company Vercel used created Doom-themed CAPTCHA to show off its AI site builder, per TechCrunch.

In order to pass the CAPTCHA, you need to kill three monsters in the popular first-person shooter game. According to the app site, the Doom CAPTCHA is meant for "for educational and entertainment purposes," so don't expect to have to prove your gaming skills every time you want to check your bank account. For that, you'll probably still have to click all the images that have stairs or motorcycles, and probably fail a few times as is the case with most CAPTCHAs.

But this CAPTCHA is just as hard, if not harder. The app has tweaked the settings to make it more challenging, by increasing the speed and bumping the difficulty to "Nightmare" level. Still, judging by the buzz it has generated online, it hasn't stopped people from trying to beat the CAPTCHA and prove they're not robots.

You can try the Doom-themed CAPTCHA for yourself by going to https://doom-captcha.vercel.app/. To pass the CAPTCHA on a desktop, use the arrow keys to aim and the spacebar to shoot. Good luck and happy hunting.
