Z-8250 heavy artillery

The heavy artillery is a Forerunner anti-air cannon and close-in weapon system that comprises the Z-8250 Anti-Ship Exterior Defense Network along with the light artillery. Used for the defense of Forerunner ships and terrestrial installations alike, it fires guided bursts of ionized particles. While the artillery can operate independently, it is most commonly used to support and defend larger weapons, such as particle cannons.

Service history
These weapons were present on the Ur-Didact's flagship, Mantle's Approach, and were used against John-117's F-41 Broadsword during the Didact's attack on Earth. A number of these weapons were also used by the Covenant remnant on Requiem, in the locations codenamed The Gate, Sniper Alley and Lockup. At Control, UNSC forces were able to hack the weapons to temporarily use them against the Covenant. Contrary to the guns previously encountered, the guns at the location Harvester were protected by energy shielding. Most of these weapons on Requiem could be deactivated manually, however Roland had to hack the energy shields of those at Harvester before Fireteam Crimson could destroy them.
