Together with games like Quake, Wolfenstein, and Unreal, Doom played a pivotal role in shaping the FPS genre. It led the way when it came to things like online multiplayer and pseudo-3D graphics and helped to popularize various game types including the mighty Deathmatch. More impressive, perhaps, was that despite its cutting-edge nature, Doom was actually very easy to run.

The original system requirements called for a processer operating at a minimum of 16MHz and at least 4MB of RAM. Even by 1993's standards, this was considered fairly reasonable, with 16MHz on the lower end of CPU averages and 4MB of RAM falling somewhere in the middle. As technology has improved over the past three decades or so, so too has the ease with which Doom can be run, with the game now even playable on a fast-food kiosk.

A photograph appearing to show a McDonald's kiosk running Doom was shared online by Twitter user jt along with a comment asking who was responsible. Unsurprisingly, perhaps, the tweet quickly attracted thousands of likes and retweets and even caught the attention of the person controlling the official Doom Twitter account, who simply responded to jt's question with the words "a genius."

Doom has been successfully installed on countless things over the years, from pocket calculators to refrigerators, and so that it can also be made to run on a McDonald's kiosk is hardly surprising. What is impressive, however, is that somebody was able to install it without getting caught, particularly as the kiosk in question appears to be right in the middle of the store and within line of sight of the counter.

The official Doom account wasn't the only one to comment on the tweet either. Many joked that the culprit probably only did it because of the long wait, while others played into the McDonald's connection with comments like "I'm lovin' it" and "McDoom." At the time of writing, jt hasn't revealed where the photo was taken, though was quick to confirm that it wasn't them, joking that if it were, they would have programmed better menu items instead.

The McDonald's kiosk joins a long list of other items on which Doom can be played, which now includes everything from a computer's BIOS to digital cameras. Earlier this month, somebody even found a way to play Doom on a lego brick. With more and more unlikely items being fitted with computer parts, one can only wonder what the iconic FPS game will become playable on next.
