Joel Murdoch has updated with various stuff his page GG Incorporated. He talks about some Half-Life stuff, Quake stuff, Unreal Tournament stuff, and most importantly some Doom stuff. He mentions a new project in the work by himself and Chris Lutz, which will most likely be based on ZDoom, as well as his coding progress:
All quiet on the Mordeth front though Gaston reports good progress. Doom Millennium is, incredibly, showing signs of life. I may have to code Lut's ungodly complicated boss after all. [. . .] I've also begun working on the long overdue Windows port of Caverns of Darkness. I had hoped Eternity would develop faster and I could release a version of the WAD that needed no custom code, but alas it hasn't happened.
