The first volume is good with it's initial Predator trilogy of novels being laid out in order, though a couple of the shorts that came after were a little disappointing. Volume 2 is about as good, though one of the main offerings is less than good.
Big Game 4/5
I once read in another review that "Big Game is Predator" which is a perfect way to put it. It captures some of the first movie's inventiveness and then adds its own creativity, but doesn't stray too far from what we are looking for, which is a suspenseful and interesting Predator story where the Predator is actually the monster. It does go into government and politics a little with its heavy military involvement, but it doesn't detract too much.
God's Truth 4/5
A B&W short that's pretty inventive. The perspective changes near the end revealing that it was narrated by someone else than what you expect.
Race War 2/5
Race War is just not good. It's long and really uninteresting, plus the main Predator doesn't even show up that often. It's a really really really forgettable story, I barely remember what it was about. Most of it takes place in a prison. It's just a missed opportunity.
The Hunted City 3/5
Takes place during the 1930's involving gangsters shooting each other and whatnot. The Predator jumps in and creates havoc.
Blood on Two-Witch Mesa 4/5
A sequel to Big Game involving the main character (I forget his name) listening to a story his grandfather tells about his ancestors encountering a Predator in the old days of cowboys and Indians.
Invaders from the Fourth Dimension 3/5
A decent story about a small child being able to see a cloaked Predator through 3-D glasses in the 1950's. It's a little strange, but entertaining which makes it worth a read.
An interesting story behind the pistol from the end of Predator 2 involving some pirates getting into a fight with each other and a Predator jumping in to finish it.
I recommend this volume to fans of AvP, but you may get some enjoyment out of it if you're just a casual comic reader.
