Brutal Doom is a mod that increases the amount of brutality in Doom. Blood effects, death animations, and character movement animations have been completely redesigned. New weapons added.

In version 21, new bloody combinations have appeared: an already killed enemy, for example, can stand on his feet for a few more seconds while the player shoots the already lifeless body and tears off pieces of meat using light weapons. Enemies have new death animations, and their remains look even more realistic.

The modder has redesigned a huge number of maps, adding new textures for walls, water and other environments. A flamethrower has also been added.
