Super Sentinel
From Halopedia, the Halo wiki
Template:Ratings Template:Forerunner Infobox
The Super Sentinel is a variant of the basic Sentinel design, but considerably larger. As with Sentinels, they are built at a Sentinel Shop, and usable by players. Intended to support anti-vehicle and anti-infantry operations, they are unable to engage aircraft, and require regular Sentinel escorts for aerial protection.[1] 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.
History
Not much is known about their history. Like most special Sentinels, they are only used in times of large Flood infections, or other considerable threats. Their only known appearances are during the Battle of the Flood-controlled Shield World and the Battle of the Apex. They were activated when the AI of the Flood-controlled Shield World autonomously initiated "Stage 3 Defense Protocols", and large amounts of Flood along with several unidentified alien species were detected. They were sent to cleanse the Flood and this possible "threat", which were the UNSC and the Covenant. They continued their function during the Battle of the Apex. The ones on this Shield World were most likely completely destroyed along with the installation when the star within it went supernova.
