Z-390 incineration cannon

The Weapon/Anti-Materiel Z-390 High-Explosive Munitions Rifle, also known as the Incineration cannon, is a Forerunner anti-matériel weapon.

Overview
The Incineration Cannon fires five streams of explosive particles, which gather into globular projectiles that oscillate along a straight trajectory. The projectiles detonate and spread upon impact with a target, ricocheting and bouncing in tall but short arc trajectories. It initially holds five whole charges at a time with one shot per charge. Each charge is automatically "loaded" after firing and cool-down. It has been described as "mixing traits of a rocket launcher, shotgun, and flamethrower."

Design details
The weapon possesses an angular design and a metallic casing. It appears to be held together, at least partly, by energy fields as indicated by its self-assembly process and reloading mechanics. Red highlights can be seen while the weapon is self-assembling and throughout the casing once assembly is complete; these highlights grow brighter when the weapon is fired.
