Z-8060 particle cannon

The Z-8060 High-Impact Particle Weapon, alternately known as the Particle Cannon, is a heavy Forerunner directed energy particle cannon used for anti-air defense.

Description
Z-8060 particle cannons are enormous floating weapons platforms. They are spherical in shape, surrounded by three curving "arms" spaced at equidistant points around the main gun assembly. The cannons project a hyper-dense beam of negatively charged ions to disintegrate any target in range. They are slow to turn, however, and are vulnerable to ground-based attacks. A well-placed hit from a small MAC in the central beam port will destroy the device.

Interestingly, this particle cannon bears a great resemblance to a certain Forerunner portal-generating machine, albeit with its "arms" protruding outwards instead of upwards.

History
A number of these weapons were encountered on Requiem in use by the Prometheans as anti-air defenses; one of the cannons obliterated a squad of Pelicans in a single hit. Two cannons were destroyed by a Mammoth siegework platform deployed to the surface by the, with Master Chief John-117 providing targeting for the Mammoth. These cannons were controlled from a central core via an AI, before it was deactivated by Cortana; causing the remaining two to fire on each other.

Trivia
The particle cannon's overall design bears a great deal of resemblance to the description of an Onyx Sentinel.
