Here's what I know about the game:
Pathfinder Arena will feature high-detail miniatures of the most iconic monsters of Pathfinder, along with its greatest heroes. The monsters summoned in the labyrinth never leave their spot, but the labyrinth shape is dynamic, and players can change it by moving the board's tiles. Monsters can then be used to attack other players, in the end leaving only one winner.
