At its heart, Doom is a very demonic game. After all, the original reserved port 666 for multiplayer matches. With a new incarnation fresh on everyone’s mind, it was only a matter of time before someone found references to “the number of the beast.”

A Redditor somehow figured out that if you visualize one of the game’s songs – Cyberdemon – using a spectrograph, you’ll see a pentagram followed by the numbers 666 repeated multiple times. The track itself is pretty creepy but why someone would even think to run this through a spectrograph is beyond me. Either way, it’s a pretty slick Easter egg and makes you wonder how many others are left to discover.
