“Things running Doom that weren’t meant to run Doom” is a category that’s been with us for years now.Pianos, printers, thescreen that shows your order in a restaurant, amotherboard BIOS,gut bacteria,Doom itself: The list goes on and on. And now that list is just a little bit bigger, as UEFN developer Jackson Clayton revealed that he’s brought the classic id Software shooter to Fortnite.
But can #Fortnite run DOOM?Obviously I can’t publish this, but it was a great way to learn more about Materials and PostProcessing in #UEFN #FortniteCreative pic.twitter.com/POlf4obJlmJuly 7, 2024

This is not Doom at all! And it’s not, really: Clayton told Kotaku that UEFN’s programming language is “too high-level” to actually get Doom running in Fortnite, so instead he had to fake it: He used Ultimate Doom Builder to export E1M1 as a 3D model, which he then imported into Fortnite’s editor. After that, he said most of the effort went into making it look “unlit and unfiltered,” and to give the space marine its familiar “choppy spinning effect.”
“It also helps a bunch that I have released a number of Doom-inspired games on Steam in the past before moving over to UEFN, so I have experience with replicating its visual and gameplay style,” Clayton told the site.
In addition to my UEFN work I’m also an indie dev!You can try my new Doom and Banjo Kazooie inspired FPS on Steam! If you catch it before the 11th there’s a 50% discount!https://t.co/Fkx2FSAGqk pic.twitter.com/V69MT7P8rmJuly 9, 2024

Clayton said he undertook the Doom-in-Fortnite project even though he knew he’d be unable to release it publicly so he could learn more about UEFN, and also as a way to “trick my friends,” which honestly is a pretty good reason for doing just about anything. They convinced him to put the video on Twitter, and the rest, as they say, is history.
