I have chosen to GM the winner of the dark heresy contest, as I feel It would be a cool scenario to run.
My role playing group (including myself) has this habit of derailing a few scenarios, so my question is if there any tips on how to keep players on track.
I know PC can do what they want but I feel this gives the GM the only option but to just improvise a story and just becomes a playground for PC.
So any help would be much welcome.
