Needler Sentinel

Note, this is not a reference to the Enforcer's weapon.

The Needler Sentinel can only be found in the level, Quarantine Zone, playing on any difficulty. There is a lone Sentinel which shoots Needler rounds on the level (instead of the conventional Sentinel Beam) and, when destroyed, it drops a Needler gun. It can be found on the leftmost side of the first of the glowing orange indoor areas within the ruins of the Sentinel Constructor Factory. Note that this gun is perfectly ordinary, unlike the Scarab Gun. This Sentinel is an oversight from Bungie's tests with Sentinels using different weapons, and was meant to be deleted. This could be because that it would not be logical for Sentinels to acquire Covenant weapons, as they only use Forerunner weapons.

It is equipped with Energy shields, and has the same boost ability and flight capabilities that an ordinary Sentinel Major has. The only difference is the Needler rounds it fires.
