Fantasy Flight Games has announced the Deathwatch Role-Playing Game, the much-anticipated third core rule book for Warhammer 40k. Players take on the role of Deathwatch Marines fighting a desperate war to restore Imperial oversight of the Jericho Reach. Space Marines are one of the most iconic aspects of the 40K universe, and I know a lot of people have been eager to get their hands on this sort of source book.
The book will use the same ruleset as Dark Heresy and Rogue Trader (so no Warhammer 3rd Edition-style-boxed sets here). It looks to be a more focused game; everyone plays some sort of Space Marine, each an elite warrior drawn from the ranks of Space Marine chapters across the galaxy.
I'm reading through Rogue Trader now, and while I think I prefer its mercantile mix of all-or-nothing trade gambles, utterly self-confident crew, and deep space horrors, Deathwatch may be a game I need to add to my library. If nothing else, I'm sure I could get my gaming group to play a one shot or two.
