For some unknown reason, the human drive to port 1993 classic DOOM to anything with a microchip remains strong, even three decades later. Famously running on calculators, freezers, and even Microsoft Notepad, we regret to inform you that someone got it working on an off-brand Fleshlight, modified so that it vibrates when you fire a weapon and again when an enemy is killed.
Dubbed "Dong DOOM" and hailed by Destructoid as "the most pleasurable version of any DOOM game to date", this unholy creation comes from the mind of Youtuber Aaron Christophel, who previously succeeded in porting the game to an electric toothbrush. Apparently, the model of adult toy in question (from Tifforun, if you want to make your own) was selected as it was the only one Christophel could find that featured a display capable of rendering the seminal shooter.
