Brutal Doom

Brutal Doom (also stylized as Brütal Doom) is a gore-themed WAD for Skulltag, Zandronum and GZDoom, created by Marcos Abenante (Sergeant_Mark_IV). As of February 14, 2013, the newest version is 0.18a. Inspired by the infamous Doom comic, the WAD features many new graphical effects, such as new death animations, fake 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 third person "fatalities" when punching enemies in berserk state. Brutal Doom has been in active development since 2010 and won a Cacoward in 2011.

Features

 * All enemies have remastered sprites and animations.
 * Many enemies have new attacks, such as the imp's pouncing attack.
 * Headshots can be done on all enemies except the cyberdemon, spider mastermind, cacodemon, demon, lost soul, and pain elemental.
 * An assault rifle 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.
 * There are more complex gibs and 3D bloodstains.
 * Berserk packs grant the player to perform fatalities on all enemies except the cyberdemon and spider mastermind. These fatalities restore the player's health.
 * Similarly to the above, many enemies also have fatality animations if they kill the player with a melee attack.
 * There are dynamic fluids that flow and splash.
 * All weapons have remastered sprites and animations. For example, the shotgun's wooden furniture has been replaced by black synthetic.
 * All weapons have been rebalanced. For example, the rocket launcher deals much more impact damage but has a lower rate of fire and a smaller blast radius.
 * Certain enemies, such as the baron of hell, hell knight, arachnotron and cyberdemon, have been made larger.
 * Similar to the above, the Wolfenstein SS has a different appearance, wearing a grey uniform and a helmet instead of the original blue uniform. Also, spectres (when not attacking) are completely invisible, save for their eyes, and Commander Keen has been replaced by an image of Justin Bieber.
 * Many enemies have been made far more dangerous, the sole exception being the arch-vile, which have been given a higher pain chance and slower attack speed.
 * The plasma gun, chainsaw and BFG9000 use the sound effects of their counterparts from Doom 3.
 * The blur artifact has been replaced with NPC marine allies. These marines start the level tied up, and can be freed with a melee attack.
 * There are three new weapons: the Mancubus Flame Cannon, the Revenant Missile Launcher, and the German MP 40 submachine gun. The former two weapons can be obtained either by killing their respective enemies with an explosion, or butchering their corpses with the chainsaw, while the latter weapon is dropped by Wolfenstein SS.
