Needler Sentinel

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

The Needler Sentinel is a glitched Forerunner Sentinel that can be found on the Halo 2 Campaign level Quarantine Zone. It is a lone Sentinel Major which shoots Needler rounds rather than the conventional Sentinel Beam and, when destroyed, drops a Needler.

The Needler Sentinel can be found on the leftmost side of the first 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 a leftover; Bungie originally planned to equip certain Sentinels with different weapons, but the idea was scrapped. This Sentinel was simply missed during the deletion process
