Jovokada Workshop spike grenade

The Spike Grenade is a new weapon that will be introduced in Halo 3. It is an invention of the Brutes, and is similar in functionality to the Plasma Grenade. When it detonates, it shoots a conical blast of spikes in one direction (kind of like a claymore mine). Like the Plasma Grenade, any player stuck by it will be sent prematurely on The Great Journey. However, unlike its luminous counterpart, the Spike Grenade sticks to the surface of ANYTHING it lands on (the plasma grenade can only stick to enemies and vehicles).

According to EGM reports, the grenade makes a distinct "Whoop-whoop-whoop" sound when thrown, which may be useful for scaring enemies or, to a more experienced player, could be used to find the thrower's position.

The Spike Grenade appears to be similar in design to the Stielhandgranate the Germans used in WW2. It has four big curved spikes on top of the grenade, and a number of smaller ones around the shaft of the grenade. This also gives it the appearance of a medieval mace.

Bungie has stated that, in order to balance the addition of a new grenade type, players will only be able to carry two of each kind in Halo 3.
