We're starting a new campaign in Only War and, since my players prefer investigation and intrigue to straight up combat, I'm adapting the Dark Heresy intro adventure Edge of Darkness to Only War.
So far, since we spent a lot of time in character creation and some scene setting, they have only just arrived in Coscarla but I thought I'd share our experience.
Spoilers for Edge of Darkness follow...
The characters are from a light infantry regiment assigned to the Tranch Occupation (I've relocated the Edge of Darkness scenario to Tranch, which doesn't require much modification since a hive world is a hive world). To bring them in from the start, the squad was on guard duty and witnessed the death of Saul Arbest, The squad medic actually participated in his autopsy.
The company command determined that the xeno control organism found need to be investigated and kept quiet. Therefore, the squad that found him has been assigned a covert mission to investigate. Nominally, they were to have been assigned to patrol the Coscarla district. In an interesting idea, the squad suggested they be assigned to conduct a "health inspection" of the district residents (as a way to look for surgical scars which could indicate other individuals implanted with the control organism) which command went along with as a good cover for their operation.
Unfortunately, their logistics roll was a horrible failure so they not only didn't get the additional medical gear they requisitioned, they lost their gas masks which were deemed unnecessary for a routine patrol.
They have arrived in Coscarla and checked in at the local enforcer station. The drug hazed enforcer Locan suggested they could find bunks at the Coscarla hostel. That's where we ended the first session.
This should be fun...
