From the campaign:
Batman™: Gotham City Chronicles is a scenario-based miniatures board game where 2 to 4 players control the Dark Knight and his allies in their never-ending battle against crime through an asymmetrical and open game system.
Each game involves an action-packed fight where two sides face off. One of the players assumes the role of the Villain and controls the most notorious criminals of Gotham City. The remaining players take control of the Heroes, who must work together as a team to foil the Villain’s plots. Each side takes turns, pitting their strategies against each other in order to achieve their objectives.
Each game of Batman™: Gotham City Chronicles is played according to a scenario which describes the plot, location of the action, setup of the game, number of turns, and the specific objectives each side is trying to achieve in order to win the game.
The game involves two opposing sides: the heroes and the villain. We wanted to represent that dynamic up front by making it obvious from the art on the boxes. That's right, boxes, because one box will not be enough to fit everything you will get.
As one would expect, the Kickstarter is doing well. They funded basically immediately, so it's on to stretch goals for the next 31 days.
