Intermezzo is a series of five post-mission scenarios for FIST.
The PDF is 2 pages, cleanly organized, and uses a lot of black and white contrast to make the text pop off of the page. It's overall easy to read, although some numbers are clumped a little close to the text that follows them.
The scenarios are mostly combat oriented, but one makes for a nice weird investigation and another is sort of cozy in its own way.
Overall, this is a great tool for adding some interstitial action to a FIST campaign. If you're running a series of missions and want a little more connective tissue to string them together---or if you just want a cool bonus act at the end of a mission---give this a look.
