Pathfinder RPG seems to be taking on a little bit of a Western-Steampunk theme after they announced their team-up with Pinnacle Entertainment Group to produce Pathfinder for Savage Worlds (see "Pinnacle and Paizo Team Up for 'Pathfinder for Savage Worlds'"). This rulebook features lots of firearms and fantasy technology to add to games of Pathfinder RPG. Players can explore the new inventor class or duel it out with the gunslinger class. It also contains Automaton ancestry for players who want to play a construct, dozens of new archetypes, and new gadgets, vehicles, and siege engines.
This book will retail for $49.99.
