Ukala Workshop Mauler

The Type-52 Pistol "Mauler" is a Covenant Jiralhanae (Brute) infantry weapon featured in Halo 3.

Introduction
It can be seen in action at the Omegathon.

The Mauler is a one-handed shotgun, a dual-wieldable version of the UNSC M90A CAWS shotgun. It is not as powerful as the UNSC shotgun, but has the bonus of dual-wieldability, and also a bayonet-like blade attached to its fore, allowing for stronger melee attacks like the Type-25 "Spiker" Carbine.

Video Glimpse
The max amount of ammo is unknown, but if you glimpse in the Halo 3 Et tu Brute video at 6:26, you can see a glimpse of what may be Brute Mauler shots being fired with which appear to be blue bolts which resemble Spiker bolts. It may be the Mauler's shots because also they spread out in a similar manner to a Shotgun.

Vehicle
The Mauler was first revealed in one of Bungie's weekly updates, which was used primarily to elaborate on the Spartan Laser. To quote:


 * "My spotter positively identified the local bravo kilo sub-chieftain. I engaged the target at [censored] meters. The shot burned an approximately [censored] diameter hole through the target and severely damaged the mauler he had just dismounted."

The use of the words "bravo kilo sub-chieftain" proves that the aforementioned mauler was manned by a Brute during the encounter. Due to this, it was believed that it was a Covenant vehicle, though this was unconfirmed.

It was at first speculated to be the so-called "Brute Ghost." However, it has since been proven that "Brute Ghost" was actually a misnomer of the Brute Chopper. Some speculated that it was a Brute flier or spectre- type vehicle of some kind, but apparently, Bungie changed their naming scheme. The Mauler was also thought to be an early misnomer of the Chopper as well.

Trivia
In a leaked video from Gametrailers, which also shows the new Flamethrower, Flame grenade and the map Guardian in action, the Mauler shoots like some kind of revolver.
