Jovokada Workshop spike grenade

The Type-2 Antipersonnel Fragmentation Grenade, more commonly known as the Spike Grenade, is a Jiralhanae (Brute) manufactured grenade.

Introduction
The Spike Grenade is believed to be the Covenant Loyalist counterpart to the Covenant Separatist Plasma Grenade. The Spike Grenade is most notable for its adhesive properties, similar to the Plasma Grenade, but with a different trajectory. This weapon uses its spikes to stick to the target and once attached, it will detonate, turning the spikes into lethal projectiles. The Spike Grenade's initial explosion is the least powerful of all the grenades in Halo 3, although the explosion is not meant to be lethal. The explosion is meant to scatter the spikes at deadly velocity, impaling enemies within range.



Aesthetics
The Spike Grenade is similar in look to the Model 24 Stielhandgranate grenade used by Germany during World War I and World War II, as well as by Imperial Japan in the latter, essentially an ovular head with a shaft protruding from its bottom. However, it derives its namesake from the notable spikes present on the grenade (four big curved spikes on top and twelve smaller ones around the shaft) as well as the shrapnel it expels.

Operation
Its utilization against Brutes is especially easy, primarily when the Catch Skull is active in Campaign. (This skull causes A.I.s to throw more grenades. Also, allies and enemies drop two grenades when killed.)  When the Brutes step forward to throw a grenade, once started they cannot stop their "throw sequence", and will be unable to dodge your grenades.

Once thrown, the spike grenade will stick itself on the first object it encounters via its spikes, whether the object be a wall, vehicle, personnel, or otherwise. They are not able to stick to the energy doors, Bubble Shields, Deployable Cover, or Jackal Gauntlet Shields, (along with some Brute Chieftain armor) and will simply bounce off. After a short delay, it will detonate into a conical blast of spikes (amidst red-blue roiling gas and spikes), perpendicular to the surface it sticks to, similar in functionality to the Claymore Mine.

It has a definite kill radius of 1 meter, or just about anything standing in the direct line of spikes fired from it, and a casualty radius of 4 meters. Because of its concentrated barrage of spikes it is less powerful than most grenades in some aspects. The spikes ricochet off of hard surfaces in confined quarters, making the spike grenade especially useful in CQB situations. The heated spikes that shoot out can kill an opponent whether or not they were near the original explosion. It is a great weapon to set up quick traps with, especially while being pursued. It can be tossed at a wall directly ahead, and then as you round a corner the blast will shoot out and kill whoever was following.

The projected spikes can travel between 1 meter and 10 meters in the direction they were projected. The spike grenade will kill most opponents and vehicles when it sticks to them but an opponent can survive the barrage of spikes if he is far enough away.

It has been observed that Spike Grenades are able to stick onto other grenades that have been thrown. This usually carries the two grenades in either direction, depending on which was thrown last. The combined explosion is obviously much greater and much more erratic, as well as much more fun to watch.

Like other grenade types, players can only carry two of these types of grenades. This is to help with balance issues. Spike Grenades are related to the Spiker, as the Spiker shoots what seem to be similar spikes to that of the Spike Grenades spikes, and was developed by the Brutes.

Tactics
This weapon is very effective at stopping or slowing down an escaping or following opponent. Simply throw the grenade at a wall in front of the enemy. If the opponent isn't smart enough to stop they are essentially mowed down by a hail of spikes. When thrown it's the fastest grenade. Use this in an enclosed area for deadly results, but be careful as it only takes a single spike to the head to kill you or seriously lower your shields. It can also be used against vehicles as it does more damage than the plasma and frag grenade and it can destroy any vehicle if stuck properly. Spike Grenades are especially good at killing Ghosts. Spike Grenades can also be thrown off course with a quick blow from a Gravity Hammer, sending the projectile in an alternate route.


 * Although this grenade cannot stick Brute Chieftains and War Chieftains, you can kill them with it by sticking their weapon.
 * The grenade is extremely useful when thrown at corners where the damage inflicted would be toward the facing walls. The spikes ejected will reflect off of walls on a shallow angle and will be focused if thrown into a corner.
 * Because it is the largest grenade, it is the easiest to detonate by shooting.
 * Although the radius of the spike grenade is limited, the area in the radius is deadly. A spike grenade is more damaging to vehicles than a plasma grenade.  It is able to destroy a Scorpion in 4 sticks, and it can stick to almost anything unlike the Plasma grenade, which can only stick to vehicles or living things.  Spike grenades are also lethal if thrown inside a bubble shield, since the shield will deflect the spikes so that they totally shower all over anyone inside it and shred them to flakes.

UNSC Remarks
“It’s like a table leg with machetes bolted to it. Who the hell makes a weapon like that? Did those guys actually get up into space on their own?”

“When you decide to throw one of these things make sure to tell everyone around you, ‘cause they are dangerous all the way there.”

“The casing is constructed of an unusual porous metallic compound. Shrapnel from the Spike Grenade reaches a temperature of approximately 270 to 315ºC, around 530ºF, and retains that heat for upwards of seven seconds, by design.”

“It’s not as heavy as it looks, but it’s still like trying to throw a softball bat.”

“Those things ain’t made to wound anyone – to make you use up time and resources treating casualties. They were designed to make you die screaming.”

“It’s like a Shotgun that shoots flaming chainsaws at mike foxtrots – except you throw it.”

Trivia

 * If you look closely at the grenades shot up in Sandtrap, you will see it is really the Spike Grenade without the rod on the back and the spikes, and is now considered a Frag Grenade.
