This game sounds fun! Pirates vs. Ninjas Dodgeball will be a downloadable game, and will support four players locally, eight players online, or four co-op. The players also aren't restricted to a left or right side of a court - they can roam around the whole area! So it's like paintball, but with a much larger ball, heh. Characters also have special moves and abilities, whatever that could mean. Did I mention there are pirates and ninjas? The game comes out sometime in 2008.
