I'm a bit late to answer but there is a guide up now in the Guides section, if you're still thinking of running this game.
@Liv I did try to contact him through Twitter, but still no reply. I would like to add a 100% and DLC % category, as well as putting more info into the rules section. There's another runner that requested a dlc% category awhile ago, and has completed a few runs of it, but still can't post them One day I'd like to see this game ran more, so maybe people will be more interested if there's more than 1 standard category for them to submit to
Requesting Mod for "Duke Nukem Forever". One of the only 2 mods has been inactive for over 3 years, and the other one I cannot get in touch with on either twitch, nor twitter.
