Warhammer: The Horus Heresy - Alpha Legion - Headhunter Prime

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.

Trained to sow chaos and destruction deep beyond enemy lines, Headhunters were specially trained units in the Alpha Legion that excelled in infiltration. With access to the highest grade of technology and weaponry, a Headhunter Prime leads a team at the behest of a senior commander who needs to make an entire world go up in smoke. The impact of such a team can leave entire systems in ruin as proof of their prowess and abilities.
