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 that 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 area within the ruins of the Sentinel Constructor Factory.

Trivia

 * Bungie originally planned to equip certain Sentinels with different Weapons but the idea was scrapped. This Sentinel was simply missed during the deletion process.
