"The gun katas. Through analysis of thousands of recorded gunfights, the Cleric has determined that the geometric distribution of antagonists in any gun battle is a statistically predictable element. The gun kata treats the gun as a total weapon, each fluid position representing a maximum kill zone, inflicting maximum damage on the maximum number of opponents while keeping the defender clear of the statistically traditional trajectories of return fire."
In short, the focus of the style is simply to shoot where the foe ought to be when they're aiming at you, and to not be where the foe ought to shoot.
The Gun Kata is a firearm-based martial art used by Kurt Wimmer and Jim Vickers in their 2002 film Equilibrium, appearing in two styles.
Long Range: As opposed to the much more famous Bullet Time dodging popularized by The Matrix, the first form consists of The Gunslinger dodging bullets by assuming a set of predefined body positions, which are theoretically supposed to reduce their body area exposed to enemy fire to the smallest amount statistically possible, all while raining lead upon the enemy with their Guns Akimbowithout even aiming at them. In his next film, Ultraviolet, Wimmer further expanded the technique by allowing an unarmed Action Girl to assume such positions among the multiple enemies so that they shoot each other instead.
Short Range: Another form of Gun Kata depicted in Equilibrium, though never explicitly named, involves dueling with a single opponent at a very close range, with both duelists wielding guns and trying to point them at each other and pull the trigger, while constantly knocking off the enemy's aim (since a fired shot cannot be blocked or parried as in unarmed combat and fencing, except whenImplausible Fencing Powersare in play). It is essentially the Wing Chun technique "Sticky Hands," with guns. Wimmer's commentary on the DVD notes that this different form is actually the result of a recurring problem during filming; they ran out of time and money to do what they originally planned and would not explain the original idea, as he intended to use it in a later movie (it's possible the final fight in Ultraviolet is the result.) Both forms were reproduced in later works, especially in anime.
While the latter form is Truth in Television as this is entirely possible, it disobeys several gun safety rules, and a much safer approach for both parties at that range would be to physically attack the opponent's person to make him unstable instead of trying to grab at his gun. The former, however, completely ignores the possibility of a target firing from cover, which is the fact of most gun fights in real life.
Compare and contrast to Gun Fu. Not related at all to the series Uta Kata. May serve as a pseudoscientific justification for the existence of graduates of the Imperial Stormtrooper Marksmanship Academy.
In most of her fights, it's not so much a kata as it is a dance - with the dance steps somehow taking her where the bullets aren't. She does this with her eyes closed.
Rushuna Tendou in Grenadier (2004) uses the close-combat form of Gun Kata during the confrontation with her Evil Twin Setsuna Oomido. The distance variant was used throughout the series to allow her to reload and shoot while spinning in place, as she had a very interesting style of reloading weapons amid combat.
The Extendeds (Stellar, Sting, and Auel) gun down dozens of Coordinators guarding the Armory One in the first episode of Gundam SEED Destiny (2005), while assuming one Ass Kicking Pose after another.
Father Tres Iquis' infamous scene in episode 2 ("Witch Hunt") of Trinity Blood (2005) almost exactly emulates the opening shoot-out in Equilibrium. This comes complete with gun flare lighting and Bloodstained Glass Windows, although it may be Justified in that Father Tres is an android.
Revy and Mr. Chang's gunplay style in Black Lagoon (2006) is very similar to the Gun Kata, although they apparently do aim their guns.
At least one episode in 2nd Barrage has Revy doing a perfect imitation of a Grammaton Cleric while standing in the open surrounded by mooks with guns, down to body, arm and hand movements. Severe Badassery ensued.
Harima (Guns Akimbo, no less) and Hanai engage in a GunKata battle in the second season of School Rumble (2006), with each of their pistols firing on full automatic. This is probably due to special effects added in later by Akira, since they were supposed to be armed only with BB guns.
In the final episode of Trigun, Vash and the Big Bad added an interesting element in their Revolver Kata. At several points they would attempt to stop the other from firing, by holding the revolver cylinder so it could not spin. Similarly they both forced the other's gun to snap open, causing the bullets to fall out of the chambers. This was only after the Wave Motion Gun segment of the fight. The fight consists of gun kata stylizing. Pulling a trigger on a gun across the room using a string, throwing several rounds at your opponent and then shooting them to make them explode, and after they emptied each other's chambers of all but one quickly-reloaded bullet, the most HARDCORE game of Russian Roulette ever.
The films of Kurt Wimmer make heavy use of this trope.
The Trope Namer is the style of gunplay used by the Grammaton Clerics in the movie Equilibrium (2002). The style was choreographed by a Karate expert, and you can see the Clerics often adopt very Karate-like stances while practicing or fighting.
Violet Song jat Shariff in Ultraviolet (2006) uses a similar style, though it is never given a name. The movements in this film are more fluid and dance-like than those used in Equilibrium, which is how Wimmer would have originally preferred.
Art Of War had a similar style fight in an empty hallway. A certain amount of respect and honor was loaded into the scene, as when they ran out of bullets, they went back to back and talked while casually reloading. Shaw and Bly spend most of the fight throwing snapshots... panic firing. It's more like Gun Fu since they still use acrobatic dodging.
Wanted has the hero running through a crowd of mooks, emptying guns into them, throwing away the empties and picking up new ones from the mooks he's shot, all without breaking stride.
The fight between Neo and Smith in the subway station was more like the second form of Gun Kata of Equilibrium mentioned above, where both combatants attempted to shoot each other in close quarter combat while simultaneously knocking their opponent's shots awry.
Angels and Demons, of all films, actually had a short, fairly realistic version. About 3/4ths of the way through the film, the assassin ambushes the inspector at close range. The assassin shoves a gun at the inspector's face, and he slaps it away just as it fires. The inspector then tries to shoot the assassin in the face, and the assassin slaps his gun away just as it fires. Then the assassin pulls a knife and kills the inspector.
El Mariachi in Desperado seems to demonstrate a sort of primitive form of Gun Kata during the fight scene in the bar. Flamenco dancing with pistols included.
A less flashy version in the sequel to Taken, where after a Mexican Standoff, The Hero and The Dragon end up intertwining their arms and emptying their guns. They then have an epic hand to hand duel to the death.
Live Action TV
The Smallville episode "Siren" actually had a fight between Lex Luthor and Green Arrow that resembled Gun Kata with Lex using a gun, and Green Arrow using a crossbow.
In Sanctuary Pilot Episode "Sanctuary for All", the villain from the past, John Druitt, demonstrates something similar to the second form of Gun Kata in his close-range gun face-off against Ashley, daughter of Helen Magus (and his own), making her miss all her shots by knocking her aim off with martial arts.
Banban Akaza in Tokusou Sentai Dekaranger uses a fighting style called "Juu Kun Do", named after Jeet Kune Do with the Japanese word for "gun" added in. There's a reason why his name sounds like "bang bang".
... has another, lesser-known style called "Golden Exhalation Style" which supports both variations of Gun Kata: defenses against incoming fire, and close-quarters combat with firearms. To be a bit annoying, Righteous Devil Style is more of a western shoot-out and duel at high noon style, and while Golden Exhalation Style does facilitate defending with your gun, it also focuses a lot on long range fire and careful aiming. For real Gun Kata, check out the homebrewed Hellfire Ballet Style.
... mostly relies on short-range flamethrower-type firearms and long-range energy weapons for personal ranged weapons; but for those that believe Kinetic Weapons Are Just Better, there's also an item called a "Prayer Piece," which is a lot closer to a Real Life revolver.
Ares Firefight in Shadowrun was developped specifically to mimic those types of movies. To quote the book: "In 2068, Ares Macrotechnology unveiled a completely new martial arts form based on the popular image of a gunfighter whirling through a melee with a pistol in each hand, shooting as much as punching and kicking. The product found its market in eager young gunslingers raised on a steady diet of trideo action flicks."
"Way of the Pistol" from GURPS: High Tech not only includes awesome handgun skills but also intimate knowledge of how pistols work, allowing tricks like taking apart the enemy's weapon in the middle of a fight.
Dungeons The Dragoning has several Gun Kata styles, designed for different weapon types and situations. Clay Pigeon is for more showy tricks like Blasting It out of Their Hands and knocking people down, Tin Star and Point Blank are more close range and physical, allowing the use of gunplay at close range or when heavily injured, Crisis Zone is the physical incarnation of More Dakka, Elemental Gearbolt uses Primitive Weapons in place of guns, but eventually has potential to One-Hit Kill enemies, and Silent Scope is for the Cold Sniper types, giving bonuses for taking your time with each shot.
Hall of Mirrors is an Equilibrium mod for Max Payne 2 that introduces the movie's famous Gun Kata into the gameplay, replacing normal Berettas with "Grammaton Sidearms" complete with the impossibly cool muzzle flashes.
Lady and Dante in the cutscenes for Devil May Cry 3. Also, Dante's fighting style "Gunslinger" has several moves resembling Gun Kata. A early cutscene in Devil May Cry 4 also involves Dante and Nero putting Gun Kata maneuvers through their paces against each other. New trailers for the Devil May Cry reboot, by Ninja Theory, shows a young Dante once again performing moves resembling Gun Kata.
In Wild ARMs 5, before the second to final boss fight in the game Dean pulls off this while warming up with the final bad guy. The bad guy uses a "sword" but it still counts.
Reiji and Xiaomu, main characters of Namco x Capcom have a combo attack called "Juu no Kata" (Which translates to "Gun Kata"). In their second appearance in Super Robot Wars OG Saga: Endless Frontier their finishing poses parody Equilibrium and Ultraviolet respectively.
City of Heroes players were begging for this for years. Dual Pistols are in the game now, and many of the power's animations resemble Gun Kata. You can also switch between types of ammo strategically, depending on whether you'd rather slow, debuff or heap extra damage on your foes.
Noel Vermillion from BlazBlue uses a fighting style that is an homage to Equilibrium, which was stated during the BlazBlue x Guilty Gear panel at AX 2009. This is most obvious during her Astral Heat, which goes through the kata seen practiced in the movie, including the finishing pose holding the backs of the guns towards one another.
In Gungrave, the main character Beyond The Grave uses the full range of gun-kata from Equilibrium (and some of Desperado thrown in for good measure). . Grave will stand in one spot, spinning, jumping and ducking while firing two13mm handguns. This is called the bullet dance (or Burst Mode), which allows Grave to fire 360 degrees. One odd fact is that the use of the recoil of the guns to spin him from side to side in mid-air. He also uses the weapons in his coffin, a large variety of machine guns, rocket launchers, missile launchers and cannon in a gunkata combination. Also, the pose made in Equilibrium where one gun is pointed up, the other down to form a cross, is one of the signature pose for the game. In the sequel, one of Grave's final Special Attacks/Demolition Shots is "Executioner's Blood", which is the standard burst but at least five times greater in power, complete with multiple view angles and a vanity pause. The game also borrows from guns in a coffin, as Grave is technically an undead hero. Unfortunately, the animation removed most of the gunkata, focusing on the 'Godfather' plot instead.
Doom The Roguelike has a trait named Gun Kata. It lets you fire pistols for free after dodging and reloads them when you kill something. Combined with the traits needed to get it (Guns Akimbo and dodging capabilities), Doomguy can end up putting out some serious amounts of lead while dancing around fireballs.
Quake III: Arena had something akin to a Gun Kata when two players in close combat picked up the railgun. Both would zoom around each other, trying to avoid the other's shots and hit his rival. The railguns had a 5 second cooldown and a near instant kill upon hitting a target, so duels could very easily resemble this trope.
The Spin AttackTequila Bomb from Stranglehold fits the definition to a T: it makes Tequila absolutely invulnerable for a short period of time, while he guns down every mook currently in the room with fluid, ballet-like movements. Bonus points for the game playing beautiful music when he does it. Double bonus points if you activate it with dual submachineguns.
Learning how to play Bullet Hell games is almost akin to this art. Since the projectiles are slow enough and typically shoot in a defined pattern, in order to score hits you have to set yourself up not only to manipulate where the enemy shoots and thus, give you a favorable formation of the pattern to dodge, but at the same time you need to be in a position to shoot the enemy back. And in fact, by rote memorization (playing the game a bunch of times), this is really the only way of surviving long enough when a up against thousands of bullets at once.
Coyote Starrk in the PS3 game Bleach: Soul Resurreccion uses Gun Kata as his basic attack style.
The Star Control series becomes this trope when playing with skilled opponents. The ships in these games can only point in one of 16 evenly-spaced cardinal directions. But if your opponent is sitting out of reach of all of your possible lines of fire, you can't hit him.
Freddie Wong is a proud practitioner, as seen in the short Alarmageddon.
In Samurai Jack, X9's fighting style was Gun Kata. Didn't do him too much good against Jack, though.
