The skies of Commorragh are equally as perilous as its bone-paved streets. The air above the shrouded spires thrums and darkens with roving murder-packs of Hellions and Reavers, engaging each other in vicious territorial battles. Anti-grav skyboards and savagely fast jetbikes vy for supremacy – when a gang is broken, or completely destroyed, their opponents dance with sickening glee above the sanity-warping metropolis the Dark Eldar call their home.
Gangs of Commorragh is a tabletop game in which two players control murder-packs of Dark Eldar Reavers and Hellions against each other in bitter combat. It combines strategy, tactics and all-out violence to create a deep and tense gaming experience.
