Based on the popular Warhammer franchise, the Deathwatch stands guard as the last line of defense at the edge of the universe, defending Mankind from inhuman horrors! Collects issues #1-4 of the Warhammer 40,000 Deathwatch mini-series. The Deathwatch is made up of the best of all Space Marines, recruited from across all Chapters to serve as the last resort against the multiple hostile alien civilizations threatening humanity. To be chosen to serve in the Deathwatch is a great honor granted only to the most elite and experienced veterans, but the specifics of their sacred duty must remain secret! Stranded and alone at the edge of the Calaphrax Cluster, one Deathwatch kill-team must hold the line against the xenos hordes that threaten to destroy humanity. Assailed on all sides, they alone have the strength of mind and body to act as humanity's first, and only, line of defense!
