Z-510 focus turret

Beam turrets are automated directed energy weapon emplacements used by the Forerunner Prometheans.

Description
Forerunner beam turrets are turrets of a similar nature to those located on Shield World 0459, but smaller in scale. They are typically constructed by Watchers and possess a deadly, long range beam weapon, akin to a Sentinel Beam. When destroyed, Forerunner beam turrets disintegrate in a manner resembling that of Promethean Knights.

A number of these turrets are hacked by Cortana on the Mantle's Approach during the Didact's attack on Earth, during which time they took on a blue light, like those of the Sentinels on Requiem, as opposed to the characteristic orange coloration of those under the Didact's control.
