Brutal Doom 64

Brutal Doom 64 is a gore-themed modification for GZDoom and Zandronum, currently being developed by Marcos Abenante (Sergeant Mark IV). The mod features new graphical effects such as smooth weapon animations, glowing particles and realistic lighting, recoil and "earthquake" effects onscreen, 3D blood animations, and more. Unlike Brutal Doom, this modification does not contain fatalities, focusing more on Doom 64's horror atmosphere. Brutal Doom 64 is compatible with The Ultimate Doom, Doom 2 and Final Doom.
