Ghost Tiger Incident is a FIST mission set in Soviet territory.
The PDF is 2 pages, with a solid, sparse cover and a surprisingly lush interior page with great visuals and a solid, cohesive WWII mission board sort of look.
Contents-wise, Ghost Tiger feels like a great bottle episode. It's got a simple premise (there's a possessed tank killing people) and it's open ended enough to allow the PCs to approach its core problem in any number of ways. It also has built in escalating stakes, and some nice atmospheric notes. And it does this all with maybe three paragraphs of text.
Overall, this is an incredibly tight and flavorful scenario. It's quick, it's direct, it has a *lot* of potential for convention or oneshot play. Absolutely pick this up if you're interested in FIST.
