Energy sword (fiction)

The Type-1 Energy Weapon, known more commonly as the Energy Sword, is a close quarters melee weapon. Used by the Sangheili, this energy weapon is more dangerous than its ceremonial nature implies.

Technical Specifications
The Energy Sword's plasma is held into a blade-like form by a small magnetic-field generator built into the handle of the weapon. This same technology is utilized in all Covenant plasma weapons. In Halo: Combat Evolved, if the Elite wielding the sword drops it, a fail-safe activates, deactivating the magnetic field without first dispensing the plasma, consuming the handle and thus destroying the weapon. In Halo 2, a similar fail-safe is active when not wielding the weapon directly. The handle must be under pressure from the handler to be activate so that the weapon can be stored safely. Also, this weapon when used properly and skillfully, is one of the deadliest in the game. It projects a magnetic field, which holds a mass of superheated plasma energy.

Varying amounts of Energy are used up when killing various foes (e.g. Flood Combat Form: 2.5 battery units). Normal swipes that merely strike a foe do not drain the Sword's battery as you must kill the foe to consume power. Therefore it may be prudent to strike a foe until it nears death and finish it off with a weapon that has ammunition that can be found more frequently in the level. Around 10 percent of the sword's energy is consumed by killing a normal opponent in Halo 2 campaign but only 3 percent of the sword's energy is consumed when killing Flood (Combat Form). Killing Infection Forms does not use any battery energy but it is highly ineffective. In Multiplayer on Halo 2 there is no limit on the amount of energy the Energy Sword can use before running out. However, like all other "power" weapons there is always one Energy Sword on the map in all standard game types. In Halo 3 there is a limit on the amount of energy, only allowing the wielder to eliminate 10 players before the Energy Sword runs out of energy and can not be used.

Cultural Significance
The Energy Sword holds a high significance in Sangheili culture. Only Spec-Ops Elites and higher are permitted to wield a sacred Energy Sword (however, in the Halo 3 level Floodgate, the first Elite Major that you come across also has one with him). Also in Halo 3, all Elites (even Minor Elites) can pull out Energy Swords and use them when stuck with a grenade. In Halo 2 at the beginning of Regret, you can rarely see a Minor Elite using one. Though it is commonly used for ceremonial purposes, it is often used in a battle as well. Sangheili culture even allows an Elite with great sword skills to mate with any female he chooses, but they may not marry. This is to ensure that 'Swordsman' genes are passed to the next generation.

Only the most skilled warriors of the Sangheili are permitted to use the weapon and it is implied that they spend years building their skills in order to become combatants in the lethal art of sword fighting. Nonetheless, despite the cultural taboo against it, any Elite can wield an energy sword with competent skill, becoming a deadly foe.[]

Variations
In Halo: Combat Evolved the Energy Sword has a cyan glow, has a far less defined edge and makes a dull clunk when striking something or someone. It is only used by Stealth Elites and Zealots. The player cannot use the energy sword in Halo: Combat Evolved, because once a Zealot is defeated the energy sword will activate a fail-safe and disintegrate. However In Halo Custom Edition, many people have made their own Energy Swords or bump possessed Zealots holding energy swords to use them, but these are not as powerful as the swords in Halo 2 and 3.

In Halo 2 the energy sword is blue with purple undertones and electrical energy crackling on it when the blade is activated. As in the previous game, it is only used by higher-ranking Elites, such as Spec-ops, Ultras and Zealots. It has an infinite battery in Multiplayer.

In Halo 3 the sword has more of a light cyan tinge similar to its appearance in Halo: Combat Evolved but still has a tint of purple near the handle. It also has an angle near the handle, whereas in the two previous games it was curved. The Sword has a limited battery supply in multiplayer(presumably because of its immense power plus it had infinite energy), and more time is needed to draw it.

Tactics
There are two ways a player in Halo 3 can attack and lunge with the Energy Sword. The first way is lunging, which occurs when the player pulls the right trigger. With this, the player lunges forward at the other player. However, this only works when the aiming reticule is lit red, indicating that the opposing player is within range.

The second attack is the straight-up melee, performed by hitting the B button (default control scheme). This performs a sort of underhand swipe (when the reticule is not red or facing an invisible opponent) or a lunge move (when the reticule is red). Though one would assume that because the energy sword's lunge and melee were the same, Bungie has indicated (via the short messages at the bottom of the screen while searching for a match in Halo 3 matchmaking), that the melee performed by hitting the B button is actually a fraction of a second quicker than those performed with the right trigger. This information can be exploited during clashes between two sword holders: if both players lunge at the same time, they will clash backwards; should one player use the right trigger and the other use the B button for their next attack, assuming that both are still within range and both attacks are thrown at the same time, the player who used the melee will almost invariably win and earn the "Bulltrue" medal (depending on host-client latency times). One way to stop a lunge attack is to throw any type of "sticky" grenade at the person lunging at you. This will kill them but you, most likely, still will die from the lunge, therefore the two cancel each other out with each person gaining a kill and death.

Another good tactic would be using melee causing you and the enemy to parry, directly after the parry spin around so that you are facing the back of the enemy, because they will lunge very little trying to go after you again, while facing their back you can lunge or melee and will get an assassination.

Yet another good tactic is when in combat with someone in an Xbox LIVE match, use your primary weapon then when close enough to the enemy (not close enough for the enemy to melee you), take out your Energy Sword and lunge at him/her. This catches the player off-guard but makes them wary of the weapon you have, thus either making that person avoid you, or backpedal when in combat with you again.

Advantages
The Energy Sword is one of the most powerful weapons in Halo 2 and Halo 3. A single lunge can kill even a fully Shielded Spartan or Covenant Elite. An over-shielded enemy can take two lunges to kill. In Halo 2 it is also one of the very few weapons that can destroy the bodies of dead Combat Forms, preventing their revival by Infection Forms. Doing this, however, will still take up energy. In Halo 2 and Halo 3, a melee will dismember unshielded Flood Combat Forms. In multiplayer for Halo 3, the lunge is shorter. Normally (but not if your opponent makes an evasive move), the lunge will connect and will eviscerate your opponent. A normal swing of the sword can deplete 1 and 2/5's of the shielding. This is enough to eliminate a normal shield, and your health. The amount of damage can be increased if you jump, run, do a lunge, do a jumping lunge, do a melee, lunging melee, etc; but can be blocked by parrying with a melee when the opponent makes a lunge, causing the loss of your shields, but not actually killing you. The sword can also parry melees with appropriate timing. This is most common with other swords, but there is picture evidence of a sword parrying a hammer strike. The primary fire button initiates a lunge when the cross hair goes red or a swipe if it is not, and the melee button initiates a fast melee. Unlike the Gravity Hammer in Halo 3, it is very hard to tell that a player has the sword when it is not the primary weapon being used, making it much easier to catch an opponent off guard, thus the player wielding it is less likely to be targeted so quickly by snipers, remember to bear in mind the time now taken to unsheathe them, as this can give them the chance to get a shot in.

Disadvantages
The Energy Sword is purely a close-quarters weapon, meaning that it is completely useless past close range. A skilled Spartan or Elite can defeat a sword wielder with low-brow weapons like the SMG or M6C Magnum by avoiding getting close to a player wielding a sword. Another disadvantage is that the Energy Sword, like most other Covenant Weapons, has a battery, requiring the player to drop the weapon once the battery is used up. Although the handle can be used as a club, the energy sword's combat effectiveness is minimal when its energy runs out (enemies, especially Flood Combat Forms, are less vulnerable to a depleted energy sword and require numerous attacks before dying.) In Halo 2 energy Swords also show through Active Camouflage, making it harder to be stealthy. However, in Campaign, the sword seemingly cannot be seen by enemies through Active Camouflage. Perhaps if they do see it they think the player is a camouflaged elite (this is unlikely, as in Uprising you can camouflage yourself and still be sneaky around Brutes with the energy sword, despite the fact that Brutes on that level will attack Elites on sight). But, in Halo 3, the sword is completely invisible if you too are invisible. Also in both Halo 2 and Halo 3, if you initiate a Sword Lunge, an opponent with a shotgun can easily fire off one shot and kill you. This also works well with a Brute Shot although it is somewhat harder to pull off without taking damage or killing yourself in the process.

Dodging Sword Lunges
It is possible to dodge a blow from the Covenant Energy Sword. To do this, one must move quickly to the right (when facing the lunging opponent), towards the hand which does not hold the sword. Conversely, to prevent your target from dodging your lunge, simply jump; jumping reduces all chances of missing or being dodged by an opponent.

Infinite Energy
In Halo 2, it is practicable to have an infinite amount of energy in the sword in campaign. All you have to do is empty all of the energy of the sword before completing the first level of two back-to-back levels (e.g. Outskirts-Metropolis). When you cross over to the next level you'll still have your empty energy sword, but it acts like a normal one. And when you cloak you can see an outline of the sword. Its great for Oracle. Just remember to have an empty sword by the end of The Arbiter, Delta Halo, or Outskirts.

Parrying
In Halo 3, a new feature has been added so that players can parry their opponent's sword by meleeing or lunging at the same time. If you pull the right trigger right before the other person makes contact, a sort of "lightsaber clang" is produced, but you do lose some or all of your shield, however when you get down to no shields, a sword clash will not affect you, though your screen will flash bright red. Be careful though; they can lunge back at you and kill you. This is sometimes known as "Fencing" and can be a game, first to die loses. A useful tactic to use in sword-on-sword fight is, once you parry, to move back out of range. You can trick the opponent into swinging and then move back into lunge distance and teach them a fatal lesson. A simple "B" melee with the sword in Halo 3 will also parry the lunge of an advancing opponent. If you time it well enough the sword fight can last indefinitely. An effective tactic if you are in the lead and get into a sword fight is to throw a plasma grenade instead of swinging, you will very likely stick them at such close range, if not, the explosive radius will probably kill one or both of you. To avoid getting killed by the explosion, you should back away from the battle after throwing the grenade. Another tactic is to throw a grenade at somebody's feet when they have the sword and if you have the sword when they will most likely jump up you can kill them as they land.

Jumping
Jumping can make the Energy Sword much more fearsome and brutally effective. Jump and point your reticle down, waiting until it turns red to lunge at the opposed. This tactic makes it harder for your enemy to track you with their reticle and sword crosshair, and thus you are more likely to win in a sword fight. By leaping upwards, your enemy cannot see you, and you can swiftly bring your attack down on the head giving you a "higher ground" battle mentality. Beware, Flood combat forms use this tactic to good effect, a lot more on Legendary. It has been noted that if you are jumping and lunge at a player on the ground who lunges up at you (in Halo 2) they may win the exchange.

Surprising attack
Put it away when you are crossing open ground. If an opponent sees you approaching with an Energy Sword, they will usually backpedal and shoot you down before you can come into range. Switch to another weapon and use a surprising lunge attack, although this tactic is not recommended for use in Halo 3 as it takes a while to fully activate the weapon.

Sword lunging vs melee
If you melee with the sword instead of pressing  RT  you can kill the player faster. Meleeing, then lunging is very hard to block, unless done at close range where two melees would win easily. Meleeing and then lunging is much faster then lunging twice; keep that in mind when playing Rumble pit. But caution, melee range with the sword is shorter than the lunge distance.

Dual wielding
The plasma sword is non-dual wieldable in every Halo game, but it is physically possible to battle with two swords at once in the accepted canon. In the Halo Graphic Novel, Rtas 'Vadum and Kusovai dual wield swords while in a training exercise. Due to a render seen in the early "Et Tu, Brute" ViDoc released by Bungie, it was conjectured that the Energy Sword would be a dual-wieldable item in Halo 3 as shown in an animation of an Elite double-wielding them, but this has since proven to be false. In concept art of Halo Wars, an Elite is seen dual wielding energy swords. A demo shows that this is possible in the final version of the game.

Visibility
In Halo: Combat Evolved and Halo 2, Active Camouflage doesn't cover the Energy Sword, resulting in an invisible user holding a very visible sword. In Halo: Combat Evolved, Stealth Elites with swords do not seem to realize that they are visible. Even with the Blind skull activated, the Sword's activation lighting will still appear, giving the user away. In Halo 3, the sword receives the full effect of the Active Camouflage and does not glow at all while Cloaking or camouflage are active. Compared to other weapons it still takes more time to become fully cloaked. Also in Halo 3 when active camouflage is activated the sword will not make a noise, making the person stealthier.

Trivia

 * The Energy Sword is Rtas 'Vadum favourite weapon. He appears to take great care of his personal Energy Sword and is the weapon that he is seen carrying all the times.
 * The Energy Sword in Halo: Combat Evolved had a failsafe switch that activated when the user released it, causing the sword to dissipate, leaving the player unable to use it.
 * An interesting theory for the above statement is that the magnetic field that shapes the plasma is always active, and that active camouflage makes it visible.
 * In Halo 2 and Halo 3 there are Covenant glyphs on the handle of the Energy Sword.
 * In the popular machinima series Red vs. Blue, the Energy Sword turns out to be a "key" that will help the gang along in their quest to save the Alien race. Church says, "Maybe it's a sword that just functions like a key in very specific situations," but Caboose conjectures, "Maybe it's a key all the time and when you stick it in people, it unlocks their death."
 * In 2008 this was released by Jasman Toys to go with their other laser tag weapons; the Plasma Pistol and Plasma Rifle.
 * It was originally going to be usable in Halo: Combat Evolved but was cut when the game became a First-Person Shooter
 * In the downloadable Vidoc "Et Tu, Brute" you can see a Brute Chieftain from Halo 3 wielding an Energy Sword.
 * On the video "Another Day On The Beach," a Minor Domo Elite wields an Energy Sword.
 * It wasn't until the fourth Age of Discovery that the elites started using Energy Swords.
 * The Energy Sword could be a discovered Forerunner weapon. It could possibly have been developed to fight the Flood.
 * The sword contains a Marathon logo on the visible hilt.
 * In the Vidoc "Et Tu, Brute" prior to the release of Halo 3, an animation of an Elite was shown dual-wielding swords.
 * Major and Minor elites are not supposed to use this weapon at any time, but surprisingly enough, you can see them wielding it in various Halo 2 levels.
 * In the level Delta Halo, where the Pelican comes to drop off marines and weapons on the temple with the energy shields, there is a pair of Energy Swords in a hidden room on the roof of the temple. Its easier in co-op. Just grenade jump and buddy jump all the way to the top until you see a hole in the roof. The room should be very dark. Once inside, there should be 2 Energy swords and 2 dead Grunts. The 2 Grunts might have been playing with the swords and killed themselves in the process.
 * Beware of third party members when dueling in Halo 3 with swords. While focused on an enemy, a third member could easily slip in and grab a double kill.
 * One thing to look out for when playing against two other people in a sword match, is that if two of you parry too long, the third person can throw a grenade in the middle of you, thus killing you.
 * In Halo 3 Beta the sword could be accessed through custom games glitch. The sword featured an extra lunge animation, raising it upwards instead of going across the screen to the left.
 * when you jump then attack, it will slash, but staying on the ground and attacking will stab
