"Squad Traits" is pretty much what you expect. It is a list of traits that affect the players as a whole instead of as individuals. What I was most impressed with was the versatility these traits can bring to the game. 

The author recommends several ways they can be used, including increasing difficulty, unifying characters thematicly, and even as temporary mechanics to go along with a mission's plot.

After reading this I am starting to think of traits in different ways!

A fun bolt-on to the ruleset that personalizes a ... what's the FIST equivalent of a MURDER?  'A TEAM'? 'A-TEAM'? .... and both provides seventeen example team-wide traits and excites the imagination with ideas for troupe level abilities / penalties / modifications.  

At a minimum, the 'negative' traits are worth keeping in the Ref's back pocket to incorporate as a penalty for particularly disastrous (and thematically associated) failure rolls.

Squad traits is a pamphlet adding a simple, but creative and clever mechanic to FIST. The players or referee choose from a list of traits which make the game easier, harder or a bit more unique. It stays true to the feel of traits in the main rules, but with great ideas for how these could impact a group all at once.

The use of art from a field manual fits the vibe and jazzes up the simple and clear layout.

Currently, the layout works better digitally than printed. This isn't a negative, as I think most users will look at it digitally (and it's easier to follow this way round than print-friendly pamphlet layouts!). If you did print it, the page break for telepaths would be a little awkward, and I think the cover might open backwards (but I don't have a printer, so can't check for sure).

I love the idea of Wave Function Expansion, spending war dice to mess with the referee is really cool. However, it might be of limited use as the referee rarely (if ever) rolls dice in the main FIST rules.

Overall, this is a great mechanical addition to a referees arsenal with a lot of potential for people to build on top of.

This is a neat idea. Makes me think of the squad mechanics in the Deathwatch RPG. Except Fist is actually easy to understand.

Squad Traits is a short supplement for FIST that adds modifiers to the entire team of PCs. These modifiers range from making the game harder, to making it easier, to making it weirder. Think of them as a slider that controls the game's micro-genre.

The PDF is 2 pages, with a bare but readable layout. There's no art or cover, but the content is solid.

Overall, this is a really clever idea and fits naturally with most FIST games. I think a lot of third party content tends to work well as standalone material, but this is a rare example of a mechanic that I think belongs in the core book.
