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 now 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.
 * There are more complex gibs and 3D bloodstains.
 * 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 For example, the shotgun's wooden furniture has been replaced by black synthetic.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 Also, spectres (when not attacking) are completely invisible, save for their eyes, and Commander Keen has been replaced by an image of Justin Bieber.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.
 * Many weapons have been replaced/upgraded and have secondary fire modes that adds various combat functions:
 * Fists (Berserk Packs/Demon Strength runes only) - Hitting the reload button will change between "Smash Mode" (basic attacks, no "fatality" moves) and "Rip And Tear" mode (player will perform fatalities on enemies except Cyberdemon and Spider Mastermind when killed, which will restore some health for "stress relief")
 * Assault rifle (replaces pistol) - Has a secondary fire option to look down the sights, making the rifle useful for snipering targets at considerable distances. Is also somewhat more powerful than the pistol. Zombieman enemies also have this as their default weapon.
 * Shotgun - Can look down the sights, grants a somewhat limited snipering ability ability. Had its power increased slightly.
 * Super Shotgun - Made more powerful, has a slight amount of recoil added, though reload time is faster.
 * Minigun (replaces Chaingun) - Can make the gun barrel spin constantly before firing. This decreases the pauses before firing but makes accuracy suffer and is best used in tight corridors or large enemy concentrations.
 * Rocket launcher - Has a "revolver style" firing chassis, forcing the player to reload after about six shots, and the pause between shots is greater, though the damage from the rockets has been increased. Cyberdemon rockets are unchanged in firing rate, though they now have the same damage properties.
 * Plasma gun - Is more powerful, has a brief pause before firing and fires slightly more slowly due to needing to reload fuel cells every so often.
 * BFG 9000 - Has a somewhat long charge pause before firing, though the attack is more focused and powerful as a result.
 * Super chaingun (Spider Mastermind only) - Made more powerful, though firing rate is slightly slower.
