Design Details編集

Plasma-rifle 02.png

A Plasma Rifle's schematics.

A plasma rifle is a Covenant directed energy weapon that uses superheated ionized gas called Plasma instead of projectile ammunition. The weapon has a power output of 100-150 KV @ 2~3 dA, and can fire 360~540 rounds per minute. Unlike the Plasma Pistol, the plasma rifle is capable of semi-automatic, and full automatic fire, this is thanks in part to its dual plasma collimator design. Placed atop one another, these collimators fire in a "stagger" taking the slow automatic fire of each individual collimator and combining it, this design allows a faster rate of fire and more rounds per second, which adds to the lethality of the weapon. Taking fire from the Type-25 DER can cause severe 2nd, 3rd, and in some cases, 4th degree burns (a 4th degree burn completely burns away all flesh, leaving only bone tissue). The Type-25 DER is the primary weapon of the Covenant’s officer corps, used by Elites and Brutes, although Jackals and Grunts have been seen using this weapon, but not as common. Against UNSC infantry, the Type-25 rifle's lethality is considerably greater than its counterpart the Type-25 pistol, due to the faster rate of fire, injuries inflicted to the victim are severe third-degree burns, with the wound being cauterized instantly upon impact. Even near misses will produce severe burns and heat trauma. Should the plasma impact an object, the impact can create fragments that may come into contact with a victim, with a crippling or lethal effect. Generally two hits from either a plasma pistol or plasma rifle will kill a light, or non armored target. Like its counterpart, over extended periods of firing can overheat the weapon, causing it to become unusable for a short period of time. In the context of the Halo games, all of the plasma weapons' strength and lethality are compensated for both the sake of ESRB rating and gameplay.


Advantages編集

プラズマライフルは主に中距離での戦闘において敵に有効な打撃を与えることが出来るが、ゆっくりと注意深く目標へ狙いをつければ長距離の目標にも有用な武器となる。 重装甲の目標を破壊する事も可能ではあるが、この武器は生物などのソフトターゲットに対して特に有効だ。 加えてプラズマライフルから発射される高速のプラズマボルトは、SPARTAN-Ⅱのような目標の動きを鈍らせる効果がある プラズマライフルを装備した歩兵はその制圧射撃によって敵歩兵の前進を阻止するだけでなく、共に戦う狙撃兵などとの協働により高い戦果を上げることが出来る。 コヴナントではこのような戦術を採用し、敵対する兵士の士気を挫いてきた。 またSPARTAN-IIと一部のエリートは、2丁のプラズマライフルを同時に扱うことができる。

Disadvantages編集

プラズマライフルは継続的に点火される時にエネルギーの急速なサイクリング、ロード、発火、およびリリースシーケンスのため非常に過熱します - その際 武器が破損することを防止するために、タイプ25DERは一時的に閉鎖されて、武器が再開する前に余分な熱が散ることを可能にするために、加熱穴を開きます。 このプロセスは武器を射撃不能にしてしまいます。 プラズマライフルのこの機能に気づいていない不注意な歩兵は射撃をすることができずそのまま死ぬこともあります。 人類の軍事専門家と科学者は、どのような原理でコヴナントのプラズマ武器が作動するのか、エネルギーの再チャージをするのかを理解できていません。 その結果、人類がプラズマ兵器を扱う場合はエネルギーの枯渇による使用不可により実質使い捨ての武器となってしまっている。 バッテリーが 10%以下になったらリチャージしてください、そうしないとプラズマライフルはトリガーを引いても不発になってしまうことがあります、これは、プラズマライフルが安定した射撃をするために必要なエネルギーがバッテリーに残っていないからである


Although the plasma rifle can strike a target at longer ranges it is not suited for long range combat, this is due to two distinct properties of the weapons operation. The first is the rate of thermal expansion which is determined by the rate of the bloom of the bolt. The second factor is speed; the faster the bolt goes, the farther the bolt will travel before the magnetic field begins to weaken, causing the temperature of the bolt to cool before the magnetic field becomes unstable and finally dissipates. The bolt also loses velocity and kinetic impact with longer travel.

Changes編集

Halo: Combat Evolved編集

The plasma rifle in Halo: Combat Evolved is far more powerful than its Halo 2 and Halo 3 counterparts; also the weapon holds the unique ability to stun opponents that were hit by high amount of plasma rounds: this effect greatly reduces the victim's ability to move and dodge the incoming projectiles and allows the user to easily hold the opponent in the weapon's firing arc. However, the drawback was that this effect is only felt with continuous fire. While stunned, the weapon will often overheat before the opponent is killed. Despite this drawback, the stun ability is a useful and potent feature in the hands of an experienced user. Beware that the plasma rifle decreases its accuracy while heating up. However, burst-firing the weapon, releasing 2-3 bolts per firing, can counteract this. In the campaign, the plasma rifle is best used against the Sentinels and Elites. You can obtain a fully charged plasma rifle by killing flood or killing Elites riding on vehicles such as Ghosts.

Changes From Halo: Combat Evolved to Halo 2編集

  • The plasma rifle is not as powerful as its predecessor and lacks the ability to stun. It is also noticeably less accurate, especially at long range. These drawbacks are compensated by a higher rate of fire and the ability to dual-wield the weapon, allowing it to be paired with a wide variety of other weapons and creating powerful combinations.
  • The changes done to the weapon are directly related to the inclusion of dual-wielding and higher rate of fire. For purposes of balance, the plasma rifle, along with many others from Halo: Combat Evolved, was tweaked to better fit the new game's fighting style. The weapon takes an opponent's shields off with five shots, but it takes many more to kill. This version of the plasma rifle behaves more as a SMG rather than a rifle.
  • It has a higher accuracy, though, when dual wielded, if both rifles are fired simultaneously, the accuracy will greatly decrease.
  • The sound effects for the plasma rifle have been changed, to give each weapon a distinct sound for better recognition.

Changes from Halo 2 to Halo 3編集

  • The plasma rifle in Halo 3, is made more powerful than its Halo 2 counterpart but is still weaker than the Halo: Combat Evolved plasma rifle. Like most of the new weapons in Halo 3, they have the same overheating rate as their predecessors, yet they fire as fast as the Brute plasma rifles in Halo 2.
  • The plasma bolts fired by the plasma rifle and all other plasma weapons in Halo 3 have been graphically redesigned to have a more vivid look. The bolts seem to travel faster than those of its previous versions, reducing the need to "lead" or "direct" the shots at mid to long ranges.
  • The weapon is more accurate than it was in Halo 2, but still not as accurate as its Halo: Combat Evolved incarnation.
  • After a few shots, the weapon becomes very inaccurate to fire. In Halo 3 multiplayer, it takes eighteen plasma bolts to kill an enemy with normal shields.

Tips And Strategies編集

The plasma rifle has limited uses in Multiplayer but is still a useful weapon, especially if dual-wielded or if playing on a close-quarters map. In Halo 2 and Halo 3, dual-wielding increases the combined rate of fire and damage. Although its range limits the weapon to close quarter and medium range fire fights, if used properly a player can quickly dispose of a far away enemy but if it's possible you should get in close. It is also advisable to carry a mid to long range weapon such as a battle rifle or sniper rifle for backup against targets outside of the plasma rifle's range. It has the fastest melee attack of any weapon except for the energy sword, and its melee is also powerful. In Halo 3, this weapon can easily overpower an Assault Rifle if the melee is used in conjunction well with the energy shield depleting shots, allowing an easy take down, however at medium range the assault rifle is likely to overpower the plasma rifle. The reason for the plasma rifle's superiority is the fact that it is more accurate than the assault rifle, and yet it inflicts a similar, if not larger amounts of damage. This weapon is also useful on overshields.

  • In close quarters, like all other weapons, it is preferable to just take out your opponent's energy shield with the plasma rifle, followed by a melee attack.
  • Like all plasma-based weaponry, it is great against shields, but it takes a slightly longer time to take down an unshielded opponent compared to human weapons like the assault rifle.
  • In Halo 2 and Halo 3, dual wielding in conjunction with a weapon that does high flesh damage (i.e. SMG or Mauler) can be very effective if the rifle is first used to deplete the target's shields, then the additional weapon is used to finish the kill.
  • Also while dual wielding plasma rifles, it is usually a good idea not to get too close to the enemy, to aviod them meleeing you while you are dual wielding.
  • In maps with the plasma rifle, you should camp in secluded places that many people walk by. The people walking by most likely won't see you; you can take out their shields easily with the Plasma Rifle and then smash them to death.
  • In Halo 2, if you pull the trigger fast enough repeatedly, you may fire faster than the default rate of fire compared to when just holding the trigger down.
  • In Halo: Combat Evolved, it is a good idea to carry a Human weapon as a secondary weapon. Use the plasma rifle until it overheats to drain an opponents shield and then shoot them with your secondary weapon. An M6D Pistol is best used for secondary but an assault rifle works well too.
  • On the level "Cortana" in Halo 3, it is useful to dual-wield plasma rifles and pick off more distant Pure Forms, espeially the Ranged Forms, which can shoot you from a long distance. By zooming in, and looking at the bottom of the screen, you will see a few red numbers indicating their distance (of up to 50 metres). Opening short bursts of fire will kill them easily, as they will flinch and cease fire when being shot. Another strategy is to use the brute shot for similar purposes.  
  • In Halo 3, it is recommended you fire in short bursts at medium range to increase your accuracy and conserve battery.

UNSC Remarks編集

  • “The Type-25 DER has no recoil to speak of; it tears the crap out of shields and you can shoot the thing all day long—it's on the heavy side though.”
  • “I realize that it uses a battery instead of a magazine, but nobody has figured out how to swap it or recharge it yet? Don’t we have scientists working for us or something?”
  • “It’s got no sight-line, it’s awkward to hold, and if it overheats it’ll cook the hair right off of your wrists.”
  • “You know, it looks delicate and so you feel like you need to hold it kind of gingerly—but then you see an Elite crack a Bravo Kilo's head with one—the things are built tough.”
  • “Yeah, and I’ve seen some Elites swinging two of them around like it was nothing—scary shit.”
  • "These things are huge—but I guess the Elites are, too—so it sorta makes sense."

Trivia編集

  • The plasma rifle is a rifle in name only; as such there is an ambiguity in its correct designation as a sub-machine gun.
  • In Halo: Combat Evolved, if your character remains idle for a minute, he'll inspect the weapon on both sides; in Halo 2 he'll open the cooling vents, and in Halo 3, he'll pull on the top.
  • Like most Covenant weapons the plasma rifle has no sights. It appears to rely entirely on the user's HUD reticule for aim assistance.
  • In Halo 3 multiplayer, with no damage modifiers on, this weapon has the third lowest shot damage difference between single and dual wield. The plasma pistol has no difference in shot damage, and the Mauler, when dual wielded, takes one more shot to kill a 2x overshielded enemy, than when single wielded. At normal shields, the shot difference is only two shots (eighteen single, twenty dual), and at 4x overshield the difference is only three shots (thirty-two single, thirty-five dual).
  • In Halo 3 the plasma rifle has a style pattern; this is best seen in well lit areas.
  • Laser tag maker Jasman Toys produced a Plasma Rifle laser tag model. There is also a plasma pistol, both of which use the same targeting frequency and are compatible. The rifle has autofire, but "overheats" after 20 rounds and the player must close the thermal vent and wait for it to "cool off".
  • In Halo: Combat Evolved, the Plasma Rifle has two shots per 1% charge, totaling 200 shots. In Halo 2 and 3, it has four, totaling 400 shots.
  • Modified Plasma Rifles appeared in Halo: Cole Protocol. They featured ammo readouts with Arabic numerals and pop-up sights, and were sold to Humans from Kig-yar black markets. This was seen as a heresy among the rest of the Covenant.
  • Plasma Rifles are much rarer in Halo 3 than the other games, possibly because they are much more powerful than the other variants. It could be because the Plasma Rifle is a Sangheili weapon, and the Jiralhanae prefer to use their own weapons like the Spiker or the Mauler instead of weapons like the Plasma Rifle or Energy Sword.
  • In Halo 2, while playing as the Arbiter, if you look carefully at your allies' their Plasma Rifles are in "overheat" mode.
  • In the Halo: Combat Evolved instruction booklet there is a Plasma Rifle picture over a picture of the Needler.
  • Grunts only need one hand to hold this weapon, compared to the two required for a Marine to hold. But in The Package, grunts are seen holding plasma rifles with two hands.
