This pdf is 4 pages long, 1 page front cover, 1 page SRD, leaving a total of 2 pages of content for 4 new gunslinger archetypes, so let's check them out!
The first one is the Deadeye, essentially a long-ranged sniper that specializes on the use of the deed of the name, making it more potent over the levels at the expense of evasive capabilities. Drifters on the other hand gain 6+Int skills, Wind and later lightning stance, more skills and are faster, but lose access to 6 deeds.
The Grim Outlaw is probably more suitable for NPCs, also gaining 6+Int skills, more skills and exchange their gun training for the abilities to expertly catch enemies off guard, shooting them in the back etc., making them especially deadly betrayers and e.g. great when a PC is a drifter hunting one of these guys. Then again, if you're more wickedly inclined, there's some fun to be had with this one.
The most interesting of the archetypes by far, though, is the harrier, who learns to lay down suppressive fire via an exclusive deed, be more efficient against enemies suffering from a negative condition and a very cool ability called improved targeting: By spending a point of grit, the harrier can shoot at body parts of foes to dazzle them, knock them back, send flying foes temporarily downwards etc. I really wish more of the new archetypes had access to these new options - they look like fun indeed!
Editing and formatting are top-notch, I didn't notice any significant glitches. Layout adheres to AA's 2-column, no-frills standard and the pdf has no bookmarks, but needs none at this length. I'm sort of torn on this one. In contrast to the Class Acts: Gunslingers-file, there is something the kind of jars me: The first 3 archetypes are more or less one-trick ponies or at least that's as far as their distinction from standard gunslingers go - they are good, don't you mind, but honestly, I would have loved to see more versatile archetypes there. After all, the harrier easily proves that the potential is here - it is honestly this archetype that made me enjoy this pdf - the rest is nice, but this one's cool. Were I to rate only the former, I'd settle for a final verdict of 3 stars, but since I really, really like the harrier and since the pdf is as cheap as it is, I'll instead settle for a final verdict of 3.5 stars, rounded up to 4.
