Well, it's nothing official but in case you have missed it, Evil Space Tomato (decorate) and Ozymandias81 (gldefs) have released some patches and additions to Batman Doom which makes them up to par with more modern releases for GZDoom like turning all the actors into DECORATE format and adding dynamic lights via GLDEFS to those actors. The overall Dark Knight experience definitely is getting better with these additions and the whole mod from Ace Team feels facelifted. Let's just hope that both modders continue their work as the addons aren't 100% finished yet. Kudos to both of you!
GZDoom patches for the original Batman Doom will be managed now by Ed The Bat, sometimes I will take a look or had some suggestions. BTW, Reborn and Gore are my primary objectives from now. Thankx
