A 2-parter, To The Slaughter is part NPC generating mechanics/representation and part campaign.
The generating mechanics took a bit of getting my head around, but they clearly have a lot of depth represented in a really concise way. With a bit of practice they would be allow referees to act as NPCs with a lot of detail and interesting motivations. The NPCs in the campaign illustrate the mechanic nicely, a clever touch.
The adventure equally took a bit to grasp, but has loads of depth, interesting challenges and a cool setting (it is pretty dark and graphic, but in a 'part of real-life that we prefer to ignore' sort of way).
