Splatoon comes out in May worldwide, and it finally has its own official website in North America. Unfortunately, there’s not much to be found there at the moment, as the full version will probably launched in a couple of days/weeks. There, you can findthe latest news straight from the Squid Research Lab though (which started posting its finding on the official Facebook page a few weeks ago), as well as some old screenshots and artworks for the game.
