So I recently finished the campaign Final Testimate with my game group and it was very successful.
The party: (Valhallans)
- an old, more than slightly insane, psyker
- a commander (started as a sergeant)
- a breacher (started as a stormtrooper)
- a weapon specialist with a sniper rifle
- a weapon specialist with a long las
A couple thoughts is that the difficulty is varied throughout this campaign, there were many encounters I needed to modify in order to present a good obstacle to the squad. The severan dominate never really proved to be a real threat, however, the orks went back and forth from being too easy and too difficult (no character is able to survive a hit from a power klaw).
Story wise it is a good campaign however there are a lot of things I needed to make up on the spot because they don't always follow the story and the book doesn't have a lot of alternative options to some sections. There were many places where I had to give the players a little push in game or incentive to follow the story.
I liked the campaign overall, I felt it was well put together and gives plenty of opportunity to continue on after the book. The players in my game were sentenced to imprisonment on a penal world for disobeying orders. They then were confronted by Colonel Schaeffer of the 13th Penal Legion and are now part of the Last chancers.
