The Super Sentinel is a variant of the basic Sentinel design, but considerably larger. They are available as a support unit in Halo Wars. They, like regular sentinels, are built at the Sentinel Shop. Intended to support anti-vehicle and anti-infantry operations, they are unable to engage aircraft, and require regular sentinel escorts for aerial protection. They cost 250 resources and require a minimum tech level of 2 to be produced and count as 2 population. They fire a beam of energy that temporarily prevents an enemy ground unit from attacking and reduces its movement speed. However, the beam does not do much damage by itself.
