Heretics (Faction)

The Heretics are a Covenant faction of Grunts and Elites who believed in the words of the Heretic Leader and joined his cause. Probably due to the Heretic Leader's belief in the words of 343 Guilty Spark, the Sentinels work with them against the Arbiter and his forces. The Heretics also fought against the Flood.

The Arbiter and the SpecOp forces led by Ultra Half-Jaw slew large numbers of Heretic forces on their quest to find the Heretic Leader.

With the death of the Heretic Leader and the destruction of their base on Threshold, the Heretics were crushed.

Heretic Grunts
Heretic Grunts wield only Needlers. They have never been seen using Plasma Pistols, the weapon more commonly used by their regular, non-Heretic counterparts, although a fair amount of Plasma Pistols are scattered throughout their base of operations. They are also not as suicidally stupid as their Covenant counterparts, and they never panic or run away.

Heretic Elites
Heretic Elites seem to use either Carbines or Sentinel Beams. Apart from the Heretic Leader himself, they never use the Plasma Rifles wielded more oftenly by their regular counterparts.
