Classic Doom was able to run through a PDF file and it's not a joke
Doom has been run on everything... ATM, printer, calculator, and even on a chainsaw, and this is not the whole list. And now you can play the cult shooter in a PDF file, and it's not a joke.
Here's What We Know
An enthusiast ading2210 was able to run Doom via a PDF file. He managed to implement it due to the fact that the PDF format supports Javascript using a separate standard library.
The output in DoomPDF is achieved by creating a text field for each row of pixels on the screen and then setting their contents to different ASCII characters. This makes it possible to get a 6-colour monochrome display that can be updated quite quickly (80 milliseconds per frame).
And to be honest, the delay is noticeable, but still, Doom in PDF already sounds cool.
You can play this miracle at this link, and learn more about it on GitHub.
Just keep in mind that not every browser will work, but Google Chrome shouldn't be a problem.
