Rapid firing Fuel Rod Shade
From Halopedia, the Halo wiki
The Rapid firing Fuel Rod Shade is a glitch in Halo: Reach affecting the Type-26 Anti-Infantry Stationary Gun, specifically the Fuel Rod variant. Triggering it causes it to fire at an incredible rate far exceeding its usual capacity.
Details
The glitch is triggered when an enemy overcharging its Plasma Pistol climbs inside the Fuel Rod Shade to man it. While a Fuel Rod Shade can normally fire only a few shots at a time before needing to cool down, said cool down time will be lost and the turrey will be able to fire infinitely and instantaneously. The shots may end up briefly "clumping" together at the mouth of the turret and not go anywhere at first, but once they are fired they form a continuous beam akin to the firing of a Scarab Gun. This may prove to be a massive hinderance to the player, who will have incredible difficulty trying to eliminate the gunner without being killed. The best option is simply to restart at a previous checkpoint, when the gunner had not yet entered the turret.
The glitch is possible on any level a Fuel Rod Shade is located at, such the very beginning of the level Tip of the Spear. The gunners controlling it will always be Unggoy, as Jackals and Drones are capable of overcharging their Plasma Pistols but can not man Shades, and typically higher ranked Unggoy, who tend to overcharge their Plasma Pistols more often. It is unknown if the glitch can be performed by the player performing an overcharge.
