From the Publisher's web site:
Welcome to the Shootist’s Guide – an accessory for use with your Aces & Eights game!
There are several parts to this product, with the first and most obvious being the collection of new Target Silhouettes. These complement the game by providing a huge new array of targets, including outlaws with hostages, mounted riders, and gunslingers in many different poses. You also get a huge number of animal silhouettes, including bears, wolves, cougars, deer, and many more, along with detailed animal statistics and additional rules on hunting and tracking!
Plus, because of the size differential introduced by the larger silhouettes (such as mounted riders), a new “Big Game” Shot Clock is also included! (Silhouettes requiring the new Shot Clock are annotated as such.)
If you're a confirmed do-it-yourselfer, this PDF gives you the opportunity to print multiple copies of the content to manipulate as you see fit. General users are better served with the print product.
NOTE: To fully use this product, YOU MUST PRINT ONE PAGE (the Big Game shotclock) ON TRANSPARENCY FILM. Please bear this in mind before purchasing the product.
(83 page PDF containing 32 pg rulebook plus 41 prints and the "Big Game" shotclock, b&w/color)
