My dad... scientist... you know the drill. – Increased damage. Shots penetrate enemies.
Usage & Description
The Hammer Buster II is intended for medium to long-range combat as its semi-automatic firing mode, strong recoil and small magazine size are unsuitable for close-range combat. In addition to its increased damage, the Hammer Buster II has a 50% additive critical hit bonus and a 15% multiplicative critical hit bonus.
The Hammer Buster II's penetration ability works similarly to Zer0's B0re, although the continuing shot receives no damage bonus. A Nisha with The Unforgiven can exploit this to inflict massive damage on enemies with overlapping hitboxes.
