Warhammer: The Horus Heresy - Alpha Legion - Exodus "The One Who Is Many" with Sniper Rifle and Power Dagger

Operating without equal in stealth, infiltration and covert operations, the XXth or Alpha Legion of the Space Marines is the one most shrouded in mystery. One of the first to reveal themselves as Traitor Brothers, this legion tricks and beguiles their foes until the very last moment, when it's too late to walk out of a cunning trap. Striking like the mystic hydra emblazoned as their sigil, they are both everywhere and nowhere at the same time; as one Brother falls, another will take his place to execute their long-plotted plans.

Able to bring entire worlds into the Imperial fold with a single bullet at the exact right time, the marksmanship of "Exodus" is second to none in Space Marine lore. Armed with the specially designed sniper rifle "The Instrument" and thought to perhaps be the work of several soldiers instead of one, "Exodus" is nonetheless credited with changing the course of entire battle campaigns due to his extreme skill and ability to insert himself exactly where he needs to be, when he needs to be there. On the onset of the Horus Heresy, "Exodus" proved to be one of the Mad Warmaster's greatest assassins.....and woe be it to the Loyalist soldier in his crosshairs.
