Yo!

        This is a demo showing everyone how cool the FINAL LEVEL is on
NIGHTMARE mode! Yeah, I've finished DOOM on NIGHTMARE mode! Have you? If
you have, then congrats, you're a master DOOMer. But if you haven't, go
ahead and try, this file might give you some ideas on how to do it. After
unzipping this file into your DOOM directory, (Copy the unzipped files
into the directory if you haven't done so) run HERO.BAT to witness a fine
example of DOOMing (And cheap shots <g>)...
