What is castle wars? Basically it involves up to 8 people sitting in catapults and launching colored balls at the other player's castles to knock down their walls before your own castle is destroyed.
The game will support up to 8 players at one time and we found that with a larger group it actually made the event even more fun. We had more players than slots, so I offered my moral support to team Pink during the first round.
Grab a group of friends and head to Montmartre to try out Castle Wars! For more information you can also check out Gillian's write-up on the same event from earlier.
