Brutal Doom 64

Brutal Doom 64 is an upcoming gore-themed WAD for GZDoom and Zandronum, currently being developed by Marcos Abenante (Sergeant Mark IV). The mod is set to feature new graphical effects such as smooth weapon animations, glowing particles and realistic lighting, recoil and "earthquake" effects onscreen, 3D blood animations, and more. The modification is currently scheduled for release on October 30, 2016. Unlike Brutal Doom, this mod will not have fatalities, focusing more on Doom 64's horror atmosphere. This mod will be compatible with The Ultimate Doom, Doom 2 and Final Doom.
