Vercel CEO Guillermo Rauch built a DOOM captcha that requires you to finish off three bad guys in Nightmare mode to prove that you’re human. According to Hackaday, the DOOM captcha is built as a WebAssembly app, which is ideal for graphics rendering, video processing, and gaming right on your browser.
However, since this is just an app on a browser and you likely want to retain the use of your mouse for switching windows, you’re limited to using the arrow keys for movement and the spacebar for firing your weapon (just like one of our editors had to back in the 1990s). Jumping around to dodge and using your cursor to look around is, unfortunately, not allowed. You could use cheats like IDKFA (all keys, weapons, ammo and 200% armor) and IDDQD (God mode), though, to increase the fun and your chance of survival.
