FIST EYES ONLY is a small bestiary for FIST.
The PDF is 10 pages, framed as old-timey slide projections. It's a cool aesthetic, and the supplement being a prop for the game is a nice touch.
The monsters in this supplement all feel well-balanced and interesting, and there's a good variety. The writing isn't always grabbing, but the concepts are good, and everything feels very useable as a GM.
Overall, if you want a nice mix of new foes to add to your FIST game, pick this up. And if you want monsters that you can present to the players in advance, as a slideshow, possibly with a whole in-character briefing, definitely pick this up.
