Github user ading2210 /vk6 has developed an unusual port of Doom. You can play it on its official website which, of course, is just a PDF file that can be downloaded on your system. It continues a long tradition of creative Doom ports, further enriching its historic legacy

Doom has been ported to devices like toasters, a fridge, and pretty much everything else you can think of, so the frontier for truly remarkable things that can run Doom is wearing thin. But one high-schooler has managed to port Doom into an actual PDF file that you can run inside your browser.

There’s a growing trend of developers flexing their muscles to make PDF documents do completely different things than what they’re intended to do. The goal is to push the boundaries of the PDF format.
