Brutal Doom

Brutal Doom (also stylized as Brütal Doom) is a gore-themed WAD for Skulltag and GZDoom, created by Sergeant_Mark_IV. As of June 7, 2012, the newest version is 0.16b. It features many new graphical effects, such as new death animations, flares and 3D blood effects for OpenGL, but also does change the gameplay by revamping the weapons (which, unlike original Doom, need to be reloaded), adding new hitboxes for headshots and featuring 3rd person "fatalities" when punching enemies in berserk state. Brutal Doom has been in active development since 2010 and won a Cacoward in 2011.

Features

 * Headshots can be done on all enemies except the Cyberdemon, Spider Mastermind, Cacodemon, Demon, Lost Soul, and Pain Elemental
 * An assault rifle that replaces the Pistol, which unlike the Pistol remains useful even late in the game and is also one of the most accurate weapons in the mod.
 * More complex gibs and 3D bloodstains.
 * Berserk state fatalities on all enemies except the Cyberdemon and Spider Mastermind.
 * Dynamic fluids that flow and splash.
 * Weapons are changed both visually and mechanically, such as the Shotgun's wooden furniture replaced by black synthetic, and the Rocket Launcher doing much more damage
 * Certain enemies, such as the Baron of Hell, Hell Knight, Arachnotron, and Cyberdemon are made larger.
 * Many weapons use the sound effects of their counterparts from Doom 3.
