The rulebook for "Pirates vs Ninjas" is now online. It contains all the rules for the complete game, as well as diagrams of the card layout and play area. Also you will find character and card abilities and much more!
Edit: A few modifications were made to the rulebook. These were mainly rule clarifications and other minor changes. With the release of the actual game coming shortly, a new, updated rulebook is being released, so this download link was taken down.
