I missed PAX and as a result didn't get a chance to see the card game in action. However, some screenshots of the event have been posted up. Let's take a more detailed look at the photos that caught my attention.
Lets take a closer look at the cards.
We can see that there are four different groups of 4 characters (16 characters) and each group has a corresponding group of 4 items (16) so we have 32 cards total. The groups appear to be Ninjas, Amazons, Tiki Villagers, and Vampires.
If anyone that attended PAX and played the card game would like to talk about their experience or add any input just drop me a line. I am very interested in how it played.
