Hi guys,
I've only recently started GM'ing a Dark Heresy game and am looking for general advice and hints. I'm running a Hive based game where the characters are mostly free range and not really of any interest to an Inquisitor yet, if ever. I'm not very familiar with DH, but have played a lot of Rogue Trader and GMing many other non-FFG systems.
What are some pit falls I should avoid?
What are things I should aim to include?
What is a good level of strength for NPC's to combat new PC's?
Any other advice?
