Drawn from the many Chapters of the Adeptus Astartes across the Imperium, the Deathwatch are an elite organisation dedicated to a single goal: the rooting out and extermination of all alien lifeforms with utter and brutal prejudice. Equipped by the Ordo Xenos of the Inquisition, Deathwatch Space Marines possess war gear purposely designed for the destruction of all aliens. In the gauntleted fists of these black-armoured warriors does the sanctity of mankind rest, in their hearts the iron will to vanquish every alien predator and wipe them from the face of the galaxy.
