The Type-1 Antipersonnel Grenade, more commonly known as the plasma grenade, is a thrown Covenant anti-personnel explosive device.[1] It is analogous to human hand grenades.

Design details[edit]

A blueprint of the Plasma Grenade in Halo: Reach.

The Type-1 Antipersonnel Grenade is a dangerous hand thrown weapon utilized by Covenant forces, typically used by Unggoy and Sangheili soldiers. The Type-1 Plasma Grenade is a spherical explosive and is made of an unknown material, the grenade in terms of design is straight forward, the activation "switch" is located on the orange colored area of the grenade. Above the activation pad is a Forerunner glyph, the glyphs seen on the Plasma Grenade are known to change with each new model and is believed to be based upon the time of manufacturing and the Covenant religious rituals. Using technology that is barely understood, even by the Covenant, the Type-1 Plasma Grenade is employed as both a thrown anti-infantry and anti-vehicle weapon.

When primed, the Type-1 plasma grenade emits a blue plasma gas, this emission is light so that the grenade does not stick to the person priming the grenade. When thrown, the plasma gas begins to intensify enough that if it comes into contact with a vehicle or infantry, the plasma will start to burn into the surface and adhere to it until detonation. The grenade contains some type of internal mechanism that allows it to distinguish between targets and background, it will stick to a soldier or vehicle, but not to a tree or wall. Post-war study and analysis have discovered that the grenade relies on heat signatures to distinguish targets.[2] Once something has been stuck with a grenade, their is no normal way to remove it, only devices like an advanced Electromagnetic shield can temporary disable the internal mechanism, however this technology is rare and only issued to special forces of both the UNSC and Covenant. After sticking to a target, or otherwise coming to a rest a three-second fuse is activated.[3] Detonation is first visible as a flash of white-blue light and the kill zone area is instantly subjected to extreme temperatures, and whatever is in the ground zero area, be it or natural and unnatural formations or otherwise, are instantly vaporized. Because there is no magnetic field to contain the plasma, it begins to cool very quickly - thermal expansion begins to take over and the resulting heat fans outward and upward continuing to burn an area up to forty feet away until the resulting flames have cooled to the point where it cannot continue to expand. After the initial explosion, the kill radius area becomes charged with negative and positive particles which will form electrical currents visible for a short period after the explosion.

The sheer destructive power the plasma grenade deals to any living creature within its vicinity is extreme; when a plasma grenade detonates on, or near a target it is subjected to extreme temperatures, killing anything within a 13 feet radius instantly[4]; damage to the body is extreme, as the heat flash vaporizes the bodies internal fluids and burns flesh and bone to an unrecognizable charred state. The concussion wave released by the grenade will also cause additional damage to anything within the kill radius. Any living being outside of the kill zone may sustain heat damage as well, as non-heat resistant clothing or flammable material may be ignited by the heat released from a detonating plasma grenade. The conclusive force released by the grenade can also harm or disorient anything just outside the kill radius and can also be affected by the flames released from the grenade - a person can also receive injuries from objects being ejected out of the kill zone at high speeds as a result of a plasma grenade detonating.

Advantages[edit]

The ability of the Plasma Grenade to stick to its target is extremely useful when encountering moving targets that could easily evade other explosive devices. This adhesive property allows the Plasma Grenade to function as both an anti-infantry and anti-vehicle weapon, where a stuck grenade can take down light vehicles and cause moderate damage to heavier ones. The explosive damage the Plasma Grenade releases is also effective at destroying objects not sensitive to the heat released by one, and can also serve as an effective support weapon as well. Plasma Grenades are also effective at disrupting electronics and shielding when they detonate.[5] The plasma grenade is known to be used by the lesser races of the Covenant as an effective suicidal weapon, a tactic most commonly used by mortally wounded or psychologically unstable Unggoy who will attach primed grenades to their bodies before hurling themselves at their enemies. Against UNSC forces the Plasma Grenade is an effective psychological weapon due to the various consequences the grenade brings to anyone in its path. Its destructive properties can also leave terrible psychological effects on a person who has witnessed one detonate on a fellow soldier and seeing the destructive damage it has done.[6]

Disadvantages[edit]

The Plasma Grenade has a three-second fuse that the Human equivalent lacks. Therefore, if the Plasma Grenade does not stick it to the target, the target will have ample time to evade the explosion. Sticking a Plasma Grenade to enemy infantry can be a gamble, as the target stuck with the grenade will have three seconds to chase down the opposite opponent and kill them as well.

Gameplay changes[edit]

Changes between Halo: Combat Evolved and Halo 2[edit]

  • The color of the grenade itself changed from a light blue to a dark blue.
  • The explosive effects of the grenade are more detailed.
  • The explosion sound effect for the grenade is different and now has more of a subtle hint of a natural explosion.
  • The Forerunner glyph on the grenade is different.
  • The explosion is less damaging.
  • The grenade's fuse timer has been reduced

Changes between Halo 2 and Halo 3 and Halo 3: ODST[edit]

  • The color of the gas and explosion are now dark blue and the grenade's explosive effect is much brighter and more detailed.
  • The model for the plasma grenade is now much more detailed and the Forerunner glyph is different.
  • The grenade now emits a high pitched noise when sticking and preparing to detonate.
  • Will sometimes stick to a wall.

Changes between Halo 3, Halo 3: ODST and Halo: Reach[edit]

  • The holographic Forerunner glyph on the casing is different.
  • The grenade is more detailed, featuring four triangular red "buttons."

Changes between Halo: Reach and Halo 4[edit]

  • The blast radius is now smaller, making it harder to get a kill when the grenade doesn't stick an enemy.

Trivia[edit]

  • It is difficult but possible to stick another grenade while it is in the air, effectively stopping and detonating both.
  • Although they do not stick to regular surfaces, Plasma Grenades will appear to sink into the ground after bouncing off of a surface.
  • In Halo: Combat Evolved, the plasma grenade has the same throwing noise as the UNSC frag grenade.
  • In the Halo 2 video "Another Day at the Beach", Gunnery Sergeant Stacker is stuck with a Plasma Grenade on his ODST helmet, but saves himself by throwing away the helmet.
  • It is possible to create a makeshift grenade launcher in Halo: Combat Evolved using two Plasma Grenades. To do this, one should throw a Plasma Grenade at the ground from a safe distance. When it hits the ground, wait a few seconds and then throw the other Plasma Grenade in front of it. If timed right, the blast from the first grenade will launch the other grenade across the map.
  • If one sticks a player with a Plasma Grenade with an overshield and kill them, one will not receive a stick medal. However, using a Spike Grenade will do so.
  • In Halo 3, Halo 3: ODST, Halo: Reach, and Halo 4, Unggoy will sometimes arm two Plasma Grenades and run towards the player, becoming suicide bombers. This feature is prominent on the level Exodus in Halo: Reach.
  • Like the Firebomb grenade and Spike Grenade, If a Flood Carrier Form is stick by a Plasma Grenade, it will not release any Infection forms.
  • Halo: Reach and Halo: Combat Evolved are so far the only games in which the player can stick themselves with a plasma grenade by throwing the grenade directly at their foot.
