While the franchise may be known for blitzing through demon-infested halls as fast as possible while also gunning down hordes of monsters, one dedicated speedrunner managed to do it faster than anyone else, shattering a long-standing world record. Given the games' emphasis on speed, it's no wonder why id Software's seminal first-person shooters are so popular amongst the speedrunning community. It's a game that's incredibly accessible to learn but infinitely difficult to master, so much so that many believe some of the older records are impossible to beat but every once in a while, someone proves the naysayers wrong.
