Brandoff's Beginner's Toolkit is an onboarding kit for new FIST GMs and players.
The PDF is 32 pages, with a clean, readable layout and a few fantastic visual gags. The art is mostly post-it notes and MS Office graphics, but they're perfect for the material and create a meta humor/horror throughline that ties the whole supplement together.
Contents-wise, what Brandoff's is first and foremost packed with is good advice. Even if you're a veteran FIST GM, you can learn something about the game from reading this. And if you're more familiar with DnD and only just dipping your toes into FIST, there's specific outreach for you to help you get used to the system.
The writing is also consistently strong and clear throughout, and there's a warm and goofy sense of humor that makes reading Brandoff's charming.
That said, the missions included in this supplement have some teeth on them. Abandon Inc isn't super dangerous, but is high-energy and grisly, with a nasty twist at the end. Hoard is a surprisingly sympathetic horror, and has a Dave Made A Maze vibe. Fluff is a The Stuff style corporate investigation. Both Hoard and Fluff would work perfectly for other horror investigation game systems, and might be a perfect match for Delta Green or Unknown Armies.
Overall, Brandoff's is an extremely solid asset for running FIST, and its scenarios are perfect for beginners and veterans alike. I don't want to say any FIST supplement is mandatory, but really consider picking this one up.
Minor Issues:
-Page 15, "Lanch is on us". I'm not sure if the typo is intentional, but if not this should be Launch.
