The player characters in Deathwatch are loyalist Space Marines, surgically and biologically enhanced super soldiers.
The game has a martial focus, as opposed to complex intrigue or detailed representation of a setting.
In Deathwatch the players take the role of Space Marines as they perform various combat missions.
These individuals are recruited from their native Chapters (fighting units of approximately 1,000 men that are broadly inspired by medieval knightly orders) to serve in squads as part of the eponymous Deathwatch, a military arm of the Inquisition, which is a vast organization composed of religious zealots with far-reaching authority, inspired by portrayals of the real-life Spanish inqusition and similar religious authorities.
Deathwatch, the third Fantasy Flight RPG based in the Warhammer 40,000 universe was officially announced on 26 February 2010.
