A long-running joke in the Doom community is that "if it has a screen, it can run Doom." There's a lot of merit to that because people have gotten the 1993 version of Doom to run on various things, including a pregnancy test, a calculator, and, more recently, the hit battle royale game Fortnite.

The latest technological advancement was discovered when X/Twitter user Jackson Clayton shared a video of 93 Doom Slayer cranking 90s. In an interview with Kotaku, Clayton shared that they discovered that the E1M1 level in Doom could be carried over to the Fortnite Unreal editor.

Clayton said they used the Unreal material system to give Doom Slayer the "choppy spinning effect, and a PostProcess material to pixellate the screen and show the gun." According to the Fortnite developer, the language used in the Unreal editor is a bit complicated to understand, so getting Fortnite to look as if it's running Doom required them to think outside the box.
