Doom is not just an influential title that's considered a classic, it's also become something of a meme in which people try new ways to play the game.
Over the years, fans have discovered odd things that can run the FPS, but recently, someone has managed to make it possible to control Doomguy using the dial on a rotary phone. A brief clip was uploaded to Twitter recently, which shows the user controlling Doom in a rudimentary way, with the phone's numbers relating to specific functions, such as turning, moving and shooting. Not only that, but the game's co-creator, John Romero, made a comment about the amusing video.
Retweeting the clip himself, the famous developer made the following light-hearted comment in response to user Yoshino's post: "Hello operator? I'd like to report a Cacodemon." Others in the thread also commented similar phone-based puns, with others impressed at how the original poster was able to make the game playable through this method. Given that ex-id Software employee John Romero is something of an influential figure, his words have no doubt caused many Twitter users to investigate the original clip.
