Sentinel Overseer

"It was the first thing we saw when we entered the place... big eyeball-ish thing, just staring at us with its huge light."

- Retired UNSC Marine, Recalling a mission in a Forerunner complex.

The Sentinel Overseer is a Forerunner construct whose purpose is to safeguard important facilities and installations. Overseers themselves resemble Monitors, albeit slightly larger and with the central coloring replaced by a bright searchlight on their "eye". They are capable of thought, although are incapable of audible speech, and are attached to walls and ceilings via a large socket in which the Monitor-like eye is placed.

Sentinel Overseers manage security systems and automated gun emplacements in small facilities located in or on larger installations, and are under the direct supervision of Monitors. Overseers are equipped with two Sentinel Beam turrets integrated into the walls that they are attached to, able to be hidden and revealed, and receive feeds from smaller security "cameras" dotted across the facilities they are tasked with maintaining. In addition they are able to control and direct local Sentinels, and add or remove targets from the Sentinels' targeting ledger, although Monitors and other such constructs are able to override these commands.
