To The Slaughter is a supplement and mini-campaign for FIST revolving around the modern corporate animal-butchering system.
The PDF is 20 pages, with a rad neon-washed cover and a readable but sort of chaotic and zine-y interior. There's hand-drawn illustrations, photobashed public domain art, jumbled fonts, and a feeling of everything being stuffed onto the page, but it's charming and doesn't interfere much with readability.
The first bit of content in the supplement is the RMPN, an extremely good piece of tech for scenario writing. It allows you to show an NPC's personality, values, emotional precarity, and a lot of other data in a small, somewhat arcane looking graphic---and it also allows you to quickly and randomly generate NPCs at a level of fairly intense emotional depth.
After the RMPN is a mini campaign about small farming vs big agribiz. It's a little goofy in tone, but has a solid narrative structure and a sense of escalating stakes and fun NPCs and setpieces.
Overall, this is a really solid supplement and would work just as well for a more lethal, grounded system like Delta Green. It *is* big CW for cruelty to animals, but if that's not a barrier for you then both the mini-campaign and the RMPN mechanic are very worth using, and the campaign is a great read even if you don't run it. If you like modern espionage horror, farmland gothic, and meaty b-movie gore, I strongly suggest picking this up.
