So, to cut a long story short, I'm running a campaign IRL where the players will start as experienced Space Wolves and, through play and before hitting Rank 2, will be seconded to the Deathwatch. One of the reasons I did this was because the Space Wolves are the only chapter I really know in detail, but also to try and give the characters connections beyond 'You were just bundled together'. But one thing that hits me is that the start of the game isn't really all that different from a vanilla Deathwatch game because really, I'm just swapping 'You're all Deathwatch initiates' for 'You're all Space Wolf veterans'. So I got thinking on ways to try to get the players to have a more involved role with each other.
So, out of curiosity and fishing for tips, have any of you done similar? And if so, how did you get the characters to see each other as more than just another gun/sword in the team?
