T261 Lucifer Arm-Mounted Gatling Gun

The T261 Lucifer Arm-Mounted Gatling Gun is a UNSC Gatling-style machine gun effective against infantry used during the Human-Covenant War.

Background
The T261 Lucifer AMGG's only known use was during the experimental HRUNTING/YGGDRASIL Mark I Prototype Armor Defense System project on Algolis. During the Battle of Algolis, a Marine with the call sign Ghost used the power armor in defense of the civilians and fellow Marines still on the planet. The T261 was used to take out a large number of Covenant infantry, before Ghost was overwhelmed and activated the self-destruct on the power armor, destroying the T261 and the suit.
