Deathwatch?

I have the Deathwatch core rulebook from 2010. Never played it. Have not even read it really. That said, I'm an armchair fan and am slightly considering running a fairly loose/light game. I only know the reviews and I will say upfront I'll probably be fairly loose with the rules and primarily focused more on facilitating the story over the game system. It would also probably be pretty railroady. Also a high possibility of PC death on the regular just to fit the particular theme I want to go with.

Anyone interested/familiar? I'm also possibly considering doing this on Roll 20 instead for the advantage of the interface.

I have Deathwatch and most of the supplements and have never gotten to play or run it... which is true for about 95% of the games I own (much to my wife's displeasure hehe)

I have an account over on Roll20 but have never played a game there... a friend posts maps and stuff there for another game
