Z-390 High-Explosive Munitions Rifle

The Z-390 High-Explosive Munitions Rifle, commonly known as the Incineration Cannon, is a usable Promethean Forerunner weapon that appears in Halo 4. Mixing traits from a Rocket Launcher, a Shotgun and a Flamethrower, the Incineration Cannon destroys all organic and non-organic material in a wide radius. It fires five streams of explosive particles in a tight spread which release upon detonation in four different directions. The explosive particles then detonate again individually, increasing the effective radius of the initial explosion to varying degrees.

Advantages (Multiplayer)

 * Any one of the explosive particles can kill a player with one hit. Because there are multiple explosive particles, it is very easy to kill multiple players with one shot.
 * It does enough damage to the Scorpion, the Wraith, and the Mantis to destroy them in one hit, but only if all the explosive particles hit the vehicle. A Warthog can survive one shot from an Incineration Cannon because not all explosive particles will hit it.

Disadvantages (Multiplayer)

 * The Incineration Cannon has only one shot per clip and reloading takes four seconds, which makes missing a shot very punishing.

Trivia

 * This weapon has some similarities to the Enforcer's Missile Launcher from Halo 2.
 * If you go into Forge and set the weapons to random, you will get an Incineration Cannon with no stock that is slightly longer than a Battle Rifle or DMR.
 * The only AI enemies who wield this weapon are Promethean Knight Commanders.
 * According to the [4 Weapon Guide],'     the incineration canon has a total blast radius of about 9 meters. In-game, it likely does not appear this big, for balance reasons most probably.
