Brotherhood? Duty? Sacrifice?
Military missions in the face of terrible foes?
That sounds a lot like Deathwatch.
Is there room for a variant ? Do we need that? Do we like that?
I see a lot more roleplaying opportunities when you play a Guardsman than when you play a stoic angel of death superwarrior, but stil , does this warrant a whole new game?
I am interested but more than a little surprised!
Curious to your thought!
