Originally shown only in Microsoft's booth at TGS, the trailer for Toylogic's Happy Wars is now available for all to see. And now that we can actually look at it, it looks really fun!
Players choose their chibi, cartoony character class (warrior, mage, or cleric), and then take part in 15-on-15 battles which mostly seem to involve crowds of players hacking away at one another while other players shoot at them with cannons. There also appear to be tower defense elements, but those seem to be less important than the fightin'.
At the official website, you can see new, cute footage of each class' special attacks. Happy Wars will break out on XBLA next year.
