Satanic Redux (v2.0)
Over at ZDoom.org, amv2k9 recently released his weapon and gameplay-mod Satanic Redux for ZDoom. It's actually a modification of M@@@H!aK & Guest's Satanic, a challenging weapons mod that puts you in the role of a necromancer that uses dark magics and enchanted weapons. The screenshots already speak for themselves but the different approach to the balance makes up for a very interesting experience, it's worth trying. You can find a full list of changes and additions (gameplay- and cosmetic-wise) in the development thread as well as the download link.
