Sentinel factory

The Sentinel Factory or Sentinel Shop is a unique Forerunner unit building structure in Halo Wars.

The structure is a type of Sentinel Constructor Factory, and it is able to construct additional combat support in the form of Sentinels once captured by a player, which can then be added to their forces. The structure can also be captured again by an enemy player, so must be defended. While this building does not need to be garrisoned, a player's units must be nearby to use it. There's usually a good amount of fighting over these online, so if you're holding it, it's best to have it guarded by a few infantry squads. The Sentinel Factory is only found on the multiplayer maps Repository and Glacial Ravine. The Sentinel Factory produces Sentinels for 100 resources, and Super Sentinels for 250 resources. The sentinels are produced instantly and they must recharge before being able to produce a new unit, much like the Support Abilities of the UNSC.

A Protector Plant is a smaller Sentinel Factory that produces Protector Sentinels instead of standard Sentinels and Super Sentinels.
