{{Quote|Holy Light!|Anonymous [[Sangheili]]}}
The Type-1 Antipersonnel Grenade is a dangerous hand-thrown weapon utilized by Covenant forces, typically used by [[Unggoy]] and [[Sangheili]] soldiers as both a thrown anti-infantry and anti-vehicle weapon. The grenade is spherical in shape and straightforward in design, with the activation "switch" 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 are believed to be based upon the time of manufacturing and the Covenant religious rituals.{{Citation needed}}


The [[Covenant]] '''Type-1 Antipersonnel Grenade'''<ref>http://www.microsoft.com/silverlight/halo3.aspx</ref>, also known as the '''Plasma Grenade''', '''Sticky Grenade''', '''Holy flare''', '''Holy light''', or the '''Demon flare''' by the [[Covenant]] is similar to the [[UNSC]] [[Fragmentation Grenade]] in that it is a hand-thrown Anti-Infantry and Anti-Vehicle weapon.
The plasma grenade's casing is made of [[Wikipedia:Programmable matter|smart matter]] programmed to stick to infantry targets. When primed, the Type-1 plasma grenade starts to vent its coolant.<ref>[https://www.halowaypoint.com/en-gb/universe/weapons/plasma-grenade '''Halo Waypoint''': ''Plasma Grenade'']</ref> After the coolant has been discharged, the plasma generator inside destabilizes and the grenade detonates after approximately 3 seconds. 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.<ref>'''[[Halo: Combat Evolved]]''', ''Game Manual'', ''page 21''</ref> Post-war study and analysis have discovered that the grenade relies on heat signatures to distinguish targets.<ref name="Waypoint">[http://www.halowaypoint.com/en-US/Halo4Guide '''Halo Waypoint:''' ''Halo 4 Interactive Guide'']</ref> Once something has been stuck with a grenade, there is no normal way to remove it, only devices like an advanced [[Armor Lock|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. Detonation is first visible as a flash of white-blue light, and the kill zone area is instantly subjected to extreme temperatures; whatever is in the ground zero area, be it natural or otherwise, is 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 areas 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.
==Overview==
[[Image:19431594-Full-1.jpg|left|250px|thumb|A Spartan about to be stuck by a Plasma Grenade, [[Halo 3]].]]
The Plasma Grenade (or ''sticky'' as it's sometimes referred to) is a specially designed  grenade that adheres to its targets. Once it has made contact with a target, the plasma grenade will immediately bond to it, making any removal impossible. The bonding mechanism holds its attraction, except to seemingly static objects, such as walls, until detonation, making it impossible to avoid its deadly explosion. Therefore, if you have been "stuck", it is a good idea to take out as many opponents around you to reclaim points. Although it will bond to any target it hits, if it attaches to a piece of armor or a weapon, removing said articles will allow one to distance themselves from the explosion. The plasma grenade once it has adhered to the target it kills instantly, so all there is to do is kiss your butt goodbye if your the one stuck.


The "sticking" mechanism is complex enough to allow the plasma grenade the ability to distinguish between targets and inanimate objects. For example, it will stick to a soldier or a vehicle, but not a tree or a wall etc. This does not, however, allow the grenade to act selectively. The plasma grenade will not distinguish between friend or foe so accuracy and caution is strongly advised when throwing it, so as not to betray your allies.
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;<ref>'''[[Halo: Ghosts of Onyx]]''', "chapter 39", ''page 359''</ref> 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 concussive 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.


The plasma grenade possesses a timer. It has a three-second fuse that counts down at the point of activation. A manual activation via a small button or a stimulated activation, such as another explosion or gunfire, will set the detonator and start the countdown. Delayed activation can also set the detonator after it either sticks to a target or otherwise comes to a rest. It is possible to tell if the grenade has been activated. A densely small and bright cloud of [[plasma]] emission will leak around the grenade as the explosive reaction takes place inside. This cloud will gradually grow to a larger diameter after each second of the countdown. A low sound is emitted by the grenade when activated, followed by two rapid beeps and a high-pitched whine just seconds before the explosion. This is the plasma grenade's standard process of detonation.
[[Image:Suicide_Grunt.jpg|right|200px|thumb|A Kamikaze [[Grunt]] charging his foes.]]
The Plasma Grenade appears to have two settings: the standard three-second fuse and a delayed manual detonation. The latter is seen in [[Halo 3]] by [[Kamikaze Grunt|suicidal Grunts]] hoping to ensure their enemy's death by exploding right next to them also known as kamikaze. In addition, the plasma grenade can be destroyed by being shot (Easily seen with the [[Sentinel Beam]]).
Also, some characters in campaign cannot be stuck. [[Brute Chieftains]] have immunity from this until their armor is knocked off. However if the [[Brutes]] shield is broken (i.e in [[Halo 2]], [[Tartarus]] can be stuck if his shield is broken), you can still stick them.
===Advantages===
===Advantages===
 
The ability of the T-1 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.<ref>'''[[Halo: First Strike]]''', "chapter 7", ''page 69''</ref> The plasma grenade is known to be used by the lesser races of the Covenant as an effective [[Suicide attack|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.<ref>'''[[Halo: The Flood]]''', "chapter 2", ''page 67''</ref>
Sticking an enemy with the plasma grenade, will always result in instant death (except for hunters).Also, except when (in [[Oddball]], or [[Juggernaut]]) the player is stuck and the option "Ballcarrier has extra life" is chosen (in [[Halo: CE]]), but in this situation the ball carrier will only have 1 bar of health. Even a fully [[Energy Shields|shielded]] [[Spartan]] or [[Elite]] (except on higher difficulty levels) cannot withstand a stuck plasma grenade. In Halo 3, high ranking Brutes on the harder difficulties can withstand a player's grenade with Mythic (death skull). Also, higher ranking Grunts on Easy, can withstand grenades thrown by their Grunt brethren if it sticks to them with Mythic. In Halo: CE Grunts will sometimes run for surrounding elites when stuck, pleading him to remove it. This results in both the grunt, the elite and the elite's team, if any, being killed.

[[Image:1212466858 Plasma-Nade.gif|right|250px|thumb|A Plasma Grenade render.]]
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.
The plasma grenade's bright blue glow and longer delay fuse allows enemies to easily notice and avoid it. It cannot be used around corners, as its bounce is negligible, and it does not roll. A player wearing a fully charged [[Overshield]] may be capable of surviving the blast even when stuck. Also, if a smart enemy is stuck when they are too close they can simply run toward you to catch you in the blast zone. In ''[[Halo 2]]'' and ''[[Halo 3]]'', a primed plasma grenade in flight can be detonated mid-air by another explosion. Weapons capable of this include the [[Rocket Launcher]], [[Brute Shot]], [[Missile Pod]], [[Frag Grenade]]s, other Plasma Grenades. The Plasma Grenade will not stick to certain types of armor such as that of a [[Scarab]] or a [[Brute Chieftain]]'s. When thrown at them, the grenade will fall to their feet, and they will probably notice it and move out of the blast radius. Ballistic or explosive weapons such as a shotgun or Brute shot will remove the plating allowing the grenade to stick. If someone throws a plasma and it hits the wall, it can bounce off the wall back down and adhere to the thrower. Also, if the opponent notices you, he/she will probably take immediate evasive action. As you will probably miss if they dodge, they will be relatively unaffected due to the tiny blast radius.
 
In addition, due to the long explosion time, if you intend to flip a vehicle by planting a grenade, the driver will have plenty of time to swerve and dodge. This also applies for infantry, as Grunts will dive out of the way if not stuck.
 
Also sometimes when trying to stick an enemy you might commit an error if you throw it to an enemies weapon,if done this by accident the plasma grenade will bounce of the enemies weapon and will cause the grenade to have little effect or the enemies will dodge it.
 
Another thing is if in [[Halo 2]] you stick a higher ranking [[Elite]] such as an [[Ultra]] it will not kill him and really takes two grenades for an ultra and higher ranks, this is a disadvantage because this makes it harder for a player to kill an Elite of higher rank.
 
If you try to throw a plasma grenade at a [[Brute]] it is hard, Brutes have be known to move a lot and dodge a lot in [[Campaign]] so you have to time it right when throwing a plasma grenade to a Brute making them extremly annoying.
 
==Effects on Health==
It has been shown that, prolonged exposure to the radiation emitted by plasma grenades, without proper protection, can cause a deviation in the neural electric pathways of the user, a disorder called [[Boren's Syndrome]]. This disease can be fatal if the person does not get treatment. Sergeant [[Avery Johnson]] is the only known living person to have Boren's Syndrome. However, this explanation may be a cover up to protect Johnson's status as a Spartan I.
 
==Theory about "Stickiness"==
[[Image:Eat My Plasma Grenade.jpg|right|thumb|180px|A [[Spartan-II|Spartan]] primes a Plasma Grenade.]]
''Note: The following is speculation.
 
The plasma grenade, may stick by producing a thin layer of plasma which, when in contact with a target, fuses to the target. The reason the plasma grenade, sticks to vehicles and characters may be due to an ability to sense Body heat and the heat from vehicles engines is most likely what causes it to stick. Since a "dead" wall doesn't emit heat, it will; however, stick to the "living" walls of a [[Flood Hive]]. One problem with this theory is that it will stick even to exposed skin (on Grunts, Jackals, or Marines as an example) even though there is no metal to fuse to - it would be nearly impossible to fuse the grenade to flesh using heat alone.


It is also theorized that there is a complex internal mechanism built into the grenade that gives it this characteristic. A gravity generator may be built into the core of the device, giving it its own force of attraction. This artificial force of attraction is highly concentrated, which is exactly why the grenade is impossible to remove.
==Gameplay changes==
===Changes between ''Halo: Combat Evolved'' and ''Halo 2''===
*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 grenade's fuse timer has been reduced


Another interesting thing, to note the fact that when a plasma grenade is primed, it does not stick to the thrower. A theory for this could be that the grenade must be primed touching something emitting heat, then leaving the heat-emitting object, thus activating its "stickiness," and finally landing and sticking to another heat-emitting object i.e. the target. This is even better proved by the fact that it will stick the person who threw it if it bounces back at them i.e a wall.
===Changes between ''Halo 2'' and ''Halo 3'' and ''Halo 3: ODST''===
*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.
*The fuse timer has been reduced by about one second.


It's possible, that the grenade has an adhesive activated by a timer. Once the grenade is activated, this timer is initiated, giving a few seconds for the thrower to release the grenade. Once the timer has run out, the adhesive activates and the surface of the grenade is as made sticky as glue by the activation of the adhesive. Although, this theory doesn't explain the environment/character principles of the grenade.
===Changes between ''Halo 3'', ''Halo 3: ODST'' and ''Halo: Reach''===
*The holographic Forerunner glyph on the casing is different.
*The grenade is more detailed, featuring four triangular red "buttons".
*The Plasma grenade, like most Covenant weapons in Halo: Reach, now has a scale pattern on it.


Another theory is that the Plasma Grenade has a energy shield hybrid shell to bounce off of walls and an internal magnet to pull it to vehicles and armor.
===Changes between ''Halo: Reach'' and ''Halo 4''===
*The blast radius is now smaller, making it harder to get a kill when the grenade doesn't stick an enemy.
*The color of the grenade has been changed to a dark purple, while the lights are a bright green.
*The grenade has a simpler design, with the Covenant glyphs noticeably absent.


Another theory states that the Plasma Grenade detects low-level and medium level electrical pulses that are in living things and that are in shield and vehicle technology. Jackal Gauntlet Defense systems emit a high rate of energy, enough to repel Human Projectiles, while the MJOLINR Armor, Elite Combat Harness, and Brute Combat Harness all are damaged by projectiles. This could mean that the Plasma grenade cannot stick to a high level electrical pulses, such as the ones that are in Jackal Gauntlets, but have sufficient energy to stick to low to medium power energy shields as well as vehicles. This would also explain why Brute Chieftains cannot be stuck, as their armor has extremely powerful shielding, albeit it can still be damaged by human projectiles.
===Changes between ''Halo 4'' and ''Halo 5: Guardians''===
*The lights on the grenade are now blue instead of green.
*The fuse is slightly longer.
*Although the blast radius remains small, a blinding effect is inflicted on players at the edge of the explosion.
*Dropped plasma grenades laying on the ground will explode when shot.


===Changes between ''Halo Wars'' and ''Halo Wars 2''===
*The Plasma Grenade emit red colors.
*The Plasma Grenade deals less damage.


{{Clear}}
===Changes between ''Halo 5: Guardians'' and ''Halo Infinite''===
*The explosion of the Plasma Grenade leaves behind "splatters" of blue plasma residue.

[[Image:Nade_stuck_h3.JPG|right|thumb|A plasma grenade explosion as seen in the ''[[Halo 3 Alpha]]''.]]
{{Linkbox|gameplay=yes|gallery=yes|gallerypage=Images of Plasma Grenade}}
*It is possible to stick a weapon then trade the said stuck weapon and live. The grenade will stay on the other weapon. Although switching for you secondary weapon won't help.
*It is difficult but possible to stick another grenade while it is in the air, effectively stopping and detonating both.
*In [[Multiplayer]] if you stick 5 people in a free-for-all (i.e. [[Lone Wolves]]) match you receive the [[Lee R. Wilson Memorial]] Achievement.
*Although they do not stick to regular surfaces, Plasma Grenades will appear to sink into the ground after bouncing off of a surface.
*In [[Multiplayer]], if you stick an enemy with the plasma grenade you are awarded with the [[Stick It Medal|Grenade Stick Medal]].  
*In ''Halo: Combat Evolved'', the plasma grenade has the same throwing noise as the UNSC frag grenade.
*In [[Multiplayer]] there is sometimes an error where the stuck grenade will only ''kill'' the opponent, and not explode. There are also occasions where a Plasma Grenade will pass through the opponent or if it does stick, it may not kill them for an unknown reason.
*In the ''Halo 2'' video "[[Another Day at the Beach]]", [[Private]] [[Walpole]] is stuck with a Plasma Grenade on his ODST helmet, but saves himself by throwing away the helmet.
*Occasionally, in [[Halo 3]], Plasma Grenades will actually bounce off players for an unexplained reason, presumably lag. Shortly after the bounce, the Plasma Grenade may teleport back onto the target.
*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.
*Another error, (usually found in the campaign) is where the grenade may entirely disappear if not looked at.  
*If one sticks an overshielded player with a Plasma Grenade and kills them, one will not receive a stick medal. However, using a Spike Grenade will do so.
*In ''Halo: Combat Evolved'', the Plasma Grenade's explosion was more of a blue cloud and was also very powerful, similar to that of a [[Needler]] in the same game. The size of the blast animation and radius also got smaller going into ''[[Halo 2]]'', and smaller still in ''[[Halo 3]]''.
*In ''[[Halo 3]]'', ''[[Halo 3: ODST]]'', ''[[Halo: Reach]]'', ''[[Halo 4]]'', and ''[[Halo 5: Guardians]]'', 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''.
*There is a glitch in ''[[Halo 2]]'' where grenades very occasionally pass through the player.
*Like the [[Orgudam Workshop firebomb]] grenade and [[Spike Grenade]], If a [[Flood Carrier Form]] is stuck by a Plasma Grenade, it will not release any Infection forms.
*In ''Halo: CE'', plasma grenade damage, like a Needler detonation and plasma pistol overcharge, is classified as an [[wikipedia:Electromagnetic pulse|EMP (electromagnetic pulse)]] and instantly drops all shields, even a full Overshield. The same held for grenades that were dropped. This was removed in Halo 2 and 3 (except for the plasma pistol overcharge), making it less effective against infantry.
*''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.
*In ''Halo: CE'' multiplayer, the human frag grenade is considered more effective against large groups of infantry, while the plasma grenade is used for single opponents or fast-moving vehicles.
*In the game ''Killer Instinct'', the Plasma Grenades used by Arbiter take the same time to explode as in ''Halo: Combat Evolved'', and the Arbiter often calls them "Cleansing Flame".
*In ''Halo: CE'', a plasma grenade inflicts 4 times the damage to a shielded Elite. So if an Elite is damaged by a plasma grenade at all when its shields are up, it will die, with few exceptions.  However, the damage multiplier is normal when damaging flesh, so on higher difficulties an Elite has a better chance of surviving a plasma grenade explosion when its shield is down.
*In ''Halo: Reach'' and ''Halo 5: Guardians'', plasma grenades that have been dropped will detonate instantly if shot with a precision weapon such as the magnum.
*In ''[[Halo 2]]'', when the [[Covenant]] use plasma grenades in battle, they will shout phrases as they throw them, such as "cleansing flame", "flare" and "holy light". This is similar to their belief of ''[[Halo]]''. Rarely though they will shout demon flare even if it is thrown by an ally.
*If [[John-117]] throws a plasma grenade, the Covenant will call it a "demon flare".
*When an NPC is stuck, they will frequently have some type of reaction to being stuck.
*Occasionally, if two plasma grenades are thrown in succession at the same spot; one will detonate, launching the other far into the air. The airborne grenade will explode in mid-air, causing a "fireworks" effect. This is easiest to perform in [[Halo: Combat Evolved]].
*If you stick a charging [[Hunter]] with a plasma grenade the Hunter will instantly turn around, exposing its back, when the grenade explodes. It is unknown why this occurs.
*It is possible to stick a [[Hunter]] on the back of the head. It will charge at you, but if you manage to get away, then the Hunter will die immediately.
*In ''Halo:CE'' if you throw a frag grenade where a group of plasma grenades are, the detonation of the frag will make the plasma grenades explode. The same occurs in Halo 3, but only during the Campaign.
*In ''[[Halo:CE]]'', Plasma Grenades take 4 seconds to detonate. In ''[[Halo 2]]'', they take 3 seconds. In ''[[Halo 3]]'', they take about 2 and 1/2 seconds.
*In ''[[Halo 3]]'', when you throw a plasma grenade, it makes a long beep before exploding.
*Plasma Grenades are favorite weapons of the "Ghosts" of multiplayer maps, nearly always sticking people in the face and chest.
*In ''[[Halo 3]]'', physics made it possible that if timed correctly at a position, when an opponent's Plasma Grenade is aimed at a player's left elbow (virtually), and when the grenade itself is about a foot away and the player throws his/her own Plasma Grenade, then both plasma grenades will stick each other and explode midway in the air.
*It is possible to stick the grenade while it is in the opponent's hand, meaning they get to throw two grenades at you.
*It has been found to be possible to stick yourself.<ref>http://www.bungie.net/forums/posts.aspx?h3fileid=22640242</ref> Often achieved by bouncing a grenade off a wall, or by getting (un)lucky and throwing one onto your knee. All grenades, even Plasma grenades also become deflected of a bubble shield so this is also an unlucky way to stick yourself.
*The above trick can be accomplished at all times if the player crouches and aims as far down as the HUD allows then throws the grenade which attaches to their foot.
*Like all grenades,it can be shot and detonated by a weapon. A [[BR55|Battle Rifle]] works best.
*It can be used for the [[Warthog Jump]].
*Occasionally, in ''Halo PC'' the Plasma Grenade will stick but will not explode and instead just disappear, called a "dud".  It is unknown whether this is intentional or due to lag or a glitch.
*Chieftains can only be stuck on their weapon, feet, and head (once the headdress is knocked off), although extremely difficult to do so.
*[[Kamikaze Grunts]] will activate two plasma grenades at once and charge the player, they are the only species known to wield two grenades at once(this occurs only in Halo 3).
*Avery J. Johnson supposedly contracted [[Boren's Syndrome]] from detonating every Plasma Grenade in a crate stolen from the Covenant at Paris IV.
*Plasma Grenades only stick to "organic" objects ([[Sangheili]], [[Jiralhanae]], [[Humans]], etc.) and bounce off anything else, with the exception of vehicles.
*On one side of the Plasma Grenade, a [[Forerunner]] Symbol like that of a [[Halo:CE]]  [[Elite]] is visible.  
*When stuck, Grunts in Halo:CE may shout, "Ohhh, not again!". This may indicate the Covenant's belief in reincarnation. That, or it may simply be a humorous anecdote inserted by a [[Bungie]] employee.
*In Halo 2 if you throw a grenade (when you don't have any) while looking down your torso will raise from your hips and you legs will extend. This is due to the model stance change. Others will see your weapon lowered.
*There is a glitch involving getting the sticky off you when you get stuck. To achieve this, get stuck first (should be easy enough, just stand still when they throw a sticky at you). Then, rush towards the nearest teleporter and get through it. Your sticky should have "magically" disappeared. This only works for Halo PC. Also, you must be close enough to the teleporter so that you can get through before the explosion.
*Through the previous glitch, you can also effectively "fall through" Blood Gulch. Time the explosion so that when the sticky blows, you are in the teleporter. You should fall, waving your arms, toward a bottomless end. This glitch is, of course, much easier with the Banshee Fall Glitch. However, this method does not involve vehicles. 
*In ''[[Halo 3]]'' the plasma grenade can be shot out of the air.
*In ''Halo 3'', sticking a Plasma Grenade to the Ghost's front "shield" is not fatal.  This is most likely because the shield protects the driver. However, a stick anywhere else on the ghost will kill the driver.
*In Forge on ''Halo 3'', there is a trick people can use with stickies to act as a kamikaze. Move right up against a wall make sure you're facing the wall), and throw a sticky at the wall so that it bounces off and sticks you. When that happens, go into editor mode and fly around. Whenever you feel like it, change back into player mode and the sticky will explode (it's funny to get right up in a player's face when this happens).
*In multiplayer, the plasma grenade is often referred to as a "blue spider".
*They are also referred to as "blueberries" or "stickies".
*It is possible to get a sticky stuck in a grav-lift. it will float in the grav-lifts gravity stream until an outside force pushes it out. This is inadvisable to do with 2 grenades to 1 grav-lift, as they will eventually stick to each other. This trick can be used in machinimas as an ambiance tool.
*Exclusively to [[Halo 3]], The plasma grenade makes a beeping sound before it blows.
*In Halo:CE, if you stay on the [[D77H-TCI_Pelican_Dropship|Pelican]] on [[343_Guilty_Spark_%28Level%29|343 Guilty Spark]], when the pelican crashes, throw a grenade at the end of the map(the grey part), and the grenade will brighten, but it won't explode.
*There is much debate about which grenade is easier to score a stick with between the [[Spike Grenade]] (type-2 Antipersonnel Grenade) and the Plasma Grenade (type-1 Antipersonnel Grenade).
*Many players prefer sticking targets with the Plasma Grenade rather than the [[Spike Grenade]].

Plasma Grenades are elegant and deadly explosive devices developed by the Covenant, and now used in large numbers by the Banished and other successor powers. The smart-matter casing allows it to stick to infantry and vehicles, making it extraordinarily deadly in the hands of skilled users. Stuck plasma grenades bypass shields.[4]

The Anskum-pattern Firebomb[2] or Type-1 Antipersonnel Grenade, more commonly known as the plasma grenade, is a thrown Covenant anti-personnel explosive device.[3] It is analogous to human hand grenades.

Design details[edit]

A blueprint of the Plasma Grenade in Halo: Reach.

"Holy Light!"
— Anonymous Sangheili

The Type-1 Antipersonnel Grenade is a dangerous hand-thrown weapon utilized by Covenant forces, typically used by Unggoy and Sangheili soldiers as both a thrown anti-infantry and anti-vehicle weapon. The grenade is spherical in shape and straightforward in design, with the activation "switch" 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 are believed to be based upon the time of manufacturing and the Covenant religious rituals.[citation needed]

The plasma grenade's casing is made of smart matter programmed to stick to infantry targets. When primed, the Type-1 plasma grenade starts to vent its coolant.[5] After the coolant has been discharged, the plasma generator inside destabilizes and the grenade detonates after approximately 3 seconds. 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.[6] Post-war study and analysis have discovered that the grenade relies on heat signatures to distinguish targets.[7] Once something has been stuck with a grenade, there 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. Detonation is first visible as a flash of white-blue light, and the kill zone area is instantly subjected to extreme temperatures; whatever is in the ground zero area, be it natural or otherwise, is 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 areas 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;[8] 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 concussive 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 T-1 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.[9] 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.[10]

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 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.
  • The fuse timer has been reduced by about one second.

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".
  • The Plasma grenade, like most Covenant weapons in Halo: Reach, now has a scale pattern on it.

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.
  • The color of the grenade has been changed to a dark purple, while the lights are a bright green.
  • The grenade has a simpler design, with the Covenant glyphs noticeably absent.

Changes between Halo 4 and Halo 5: Guardians[edit]

  • The lights on the grenade are now blue instead of green.
  • The fuse is slightly longer.
  • Although the blast radius remains small, a blinding effect is inflicted on players at the edge of the explosion.
  • Dropped plasma grenades laying on the ground will explode when shot.

Changes between Halo Wars and Halo Wars 2[edit]

  • The Plasma Grenade emit red colors.
  • The Plasma Grenade deals less damage.

Changes between Halo 5: Guardians and Halo Infinite[edit]

  • The explosion of the Plasma Grenade leaves behind "splatters" of blue plasma residue.

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", Private Walpole 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 an overshielded player with a Plasma Grenade and kills them, one will not receive a stick medal. However, using a Spike Grenade will do so.
  • In Halo 3, Halo 3: ODST, Halo: Reach, Halo 4, and Halo 5: Guardians, 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 Orgudam Workshop firebomb grenade and Spike Grenade, If a Flood Carrier Form is stuck 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.
  • In the game Killer Instinct, the Plasma Grenades used by Arbiter take the same time to explode as in Halo: Combat Evolved, and the Arbiter often calls them "Cleansing Flame".
  • In Halo: Reach and Halo 5: Guardians, plasma grenades that have been dropped will detonate instantly if shot with a precision weapon such as the magnum.
