Summary
The Weapon/Anti-Matériel Z-390 High-Explosive Munitions Rifle, more commonly known as the Incineration Cannon, is a Forerunner anti-matériel weapon originally used to combat the Flood. The Incineration Cannon fires five streams of explosive particles in a tight spread which release in four different directions upon detonation. The explosive particles then detonate again individually, increasing the effective radius of the initial explosion.
River of Light is a special variant of the Z-390 High-Explosive Munitions Rifle upgraded with increased damage, a wider projectile trajectory, increased battery capacity, faster charging speed, and faster heat dissipation. It unleashes long bursts of seven energy blasts if charged up.
Heartseeker is a special variant of the Z-390 High-Explosive Munitions Rifle that fires slower-moving but more powerful energy charges with very strong homing behavior with increased range and a wider blast radius over the standard weapon.
