Protector plant

A Protector plant is an underground variant of the Forerunner Sentinel manufacturing facility, capable of constructing Protector Sentinels. Two such facilities were located within the shield world Etran Harborage.

The Protector plant appears exclusively in the Halo Wars Skirmish level Labyrinth. Unlike other bonus buildings, the building cannot be garrisoned. Players with a unit nearby may access its menu and purchase Protector units, which can then be attached to friendly units as support. The Protector units are produced instantly and construction must recharge before being able to produce a new unit, much like the UNSC leaders' Support Abilities.

The visually-similar Sentinel shop produces Protector Sentinels instead of Aggressor Sentinels and Super Sentinels.
