A software engineer has ported Doom to a standalone Word document. The single 6.6MB document file, available via GitHub, contains a source port of doomgeneric. Users will need a modern version of Microsoft Office/Word on an x86 computer system, and eschew security warnings, to enable the VBA macro in the document to run.
Save you a little digging:

And, like the PDF, I can't get it to fly.
