In my view, the best 40KRPG.
The 'Deathwatch' provides a good narrative device for pulling together Marine characters from a variety of otherwise disparate Chapters, while the military squad role choice ensures that teamwork is still paramount. The characters are competent in combat situations t a near superhuman level, although they never seem to quite lose their human condition. While the main focus is on military assault style missions, you can still throw a bit of investigation and exploration into their stories, so it's actually becomes a more flexible premise than the other games in the series. Moreover, almost every gamer will instantly recognise the iconic Space Marines, and be able to settle into play with little need for exposition.
The presentation and organisation within the book is outstanding, as you might expect, but the file itself is much smaller meaning your iPad/computer won't suffer a heart attack each time you save it.
