Dual Maulers – Halo 3Halo 3 wasn’t too innovative a game, if you think about it. For me, the best thing that came out of it was the Mauler. This baby is a pistol-like shotgun with an awesome rate of fire. The fact that it’s so small makes you see the shotgun as a versatile weapon rather than a huge, clumsy gun that’s hard to handle. By itself this gun isn’t as powerful as the standard Halo shotgun. Get two and it’s a whole new story.
You can use the left and right trigger on your Xbox 360 controller to fire the guns in quick succession, or fire both together for an extremely powerful punch. Two of these guns are way more powerful than almost anything in close-range combat. While it isn’t very useful in long-range combat, this gun still packs a punch in the medium range.
