Relatively new to the DH/DW world, forums, and gaming systems, so I apologize if this is way off base or if it is/has been discussed. Reading through the material for both, it seems the typical DH game relies heavily on investigation, intrigue, subtlety and social interaction, while Deathwatch relies heavily on combat. I was thinking it might be interesting to have a group run two sets of characters. One group as acolytes - mayhap reporting to Inq. Quist, and another group as DW marines who are called to service based on the information gathered by the Inquisition. There are no absolutes here, as each group can expand into each others domains (social DW and combat DH), but I think it could be an interesting way to run a campaing. Someone I game with likened it to playing out "Law and Order" episodes.
Any thoughts or ideas are welcome.
