Bulkarm β (Beta) is the next 2nd generation Hexa Gear to be developed by MSG after Bulkarm α (Alpha). Like Bulkarm Alpha, there is a wide range of variant Beta models in use, and these units are often spotted on the battlefield.
The Bulkarm Beta unit is outfitted with support devices on the legs for mobility purposes, giving the unit a comparatively high movement speed. Like the Alpha unit, the Beta unit features the Iron Fist operators that favor strength, but the flexibility of the wrist joints has been improved, allowing the operators to be equipped with a wider range of weapons. This feature allows the model to be customized with a variety of weapons, from long-range cannons to close-combat gear.
