The War of Succession in the Pacific was famous for its indoor battles. The K8 is a hand-crafted blunderbuss created by the Heaven's Bane squadron, designed for indoor confrontations.
The clip consists of four explosive projectiles. The first three are low intensity, oriented more towards encounters in passageways. The last is a large-calibre projectile capable of wreaking havoc in more open spaces.
You can obtain Hans' K8 Blueprint playing the 'The Beast's Lair' mission of the Wardog Fury Campaign.
