This pdf is 5 pages long, 1/2 page editorial, 1 page SRD, leaving 3.5 pages of content, so let#s check this out!
This pdf provides us with 3 automata of the inevitable subtype:
The CR 4 Alpha-scouts are skilled in hunting their quarry and are preternaturally quick.
The CR 8 Betas come with broader training and an enmity-field and its defensor shield and blast batons interact in a rather cool and unique way with this signature ability.
The final automaton is the CR 14 Gamma can be considered as a specialized inevitable to hunt down psionically active individuals and is immune to psi-powers as well as capable of emitting a dispelling pulse - a nice alternative to psi-killers.
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to a two-column standard and each of the inevitables herein comes with its own nice b/w-artwork. The pdf has no bookmarks, but needs none at this length. The overall quality of the inevitables herein is top-notch and personally, I love the concept of them - having finally also inevitables to mercilessly police psionicists is neat indeed. Especially the cool interaction of the Beta's leech field with its equipment is nice indeed - I hope to see more of the kind in the future. On the down-side, the Alpha is not as awesome and rather mundane. But then there's the almost unbeatable price - for this low price, I think you'll definitely enjoy the file. Thus, I'll settle for a final verdict of 5 stars for this micro-bestiary.
