So I guess since this guy's still in betamode, I may as well go ahead and upload what I'm calling "v4" (for some weird reason) since most of the major new "surprise" is done and could use some proper testing. Hooray for blatant crowdsourcing!
Anyway, the biggest change thus far is
Heretic, Hexen, and
Strife support, largely because "why not?" (though actually because amv2k9 started a patch and I couldn't resist merging it in -- thanks for making this happen, sir!) Though there are probably bugs, all games should
hopefully be playable all the way through, and I've at least played through all of Hexen so can attest to the fact that it managed to not break horribly at least once through.

I added some notes about the new game on the first post that may be worth reading, but it's mostly just item descriptions (since there are some new ones that aren't documented in xa-necro.txt yet) and some other randomness. At any rate, the download link:
