Viking-themed mod for Doom, but since there's a standalone version (no Doom or Heretic required) I think it fits here.
The standalone version includes Chocolate Doom and it's ready to play.

It's resolved.

Forgive me any such have been listed before--I didn't see any when looking through the forum and thread--but are there any good mods--in particular custom campaigns--for Hexen II?

I just finished playing the base game, and thoroughly enjoyed it. Portal of Praevus is, of course, not available. Thus I'm somewhat hungering for something else to try--fan-missions!

(And bonus points if they add new weapons or enemies!)

Sorry to revive a ~4 year old thread, I just wanted to add:

I was the lead programmer on Hexen: Edge of Chaos (a Doom3 mod/TC). We originally intended to release 3 episodes but I disbanded in ~2010 after the first release to work different projects (5+ years is a long time to spend on a single game) and apparently the rest of the team had also moved on since then (they continued to work on it for the next 1+ year, at least). Tonight, I got into a weird special-interest thingy and decided to build up a portfolio of my past projects, and realized hexenmod.net is no longer maintained (looks like it was bought by domain squatters).

I still have the source. I still have the mod laying around somewhere. It's also very likely still available on moddb.com, so that's where you should look first. But if for any reason it has disappeared, feel free to email me about it and I'll make available whatever file(s) or sources are missing. b capta in404 at gee male.
