The day of conquest is nigh! Teeming from the dark corners of Mankind`s realm come the Genestealer Cults. Alien hybrids possessed of limitless patience and deadly, slow-burning hatred for the Imperium, these zealous masses spend generations in painstaking preparation for the perfect time to strike. Thousands of cultist voices are raised in prayer to their Patriarch, a living xenos god from beyond the stars. Up-gunned transport vehicles careen from civilian buildings to bring their monstrous passengers to the front lines, even as darkly charismatic leaders and supernaturally gifted special operatives dismantle the armies of the foe. A menace unseen by the eyes of the sane has finally revealed itself, and it is ready to conquer the galaxy.
