Tales of the World: Tactics Union's official site has properly opened today with info on the story, the characters and the game's system, as well as a new trailer to back it all up.
The trailer mainly focuses on introducing the characters and showing off their gameplay. It also had some sort of theme song, but they never mentioned the title or anything.
The trailer aside, all the info about the story and the game system were already covered previously in this post. The short character profiles will be something we'll update on later. The site also has a section for "DLC", but it's still closed at the moment.
The game will be out on July 7, 2012 for the Android via KDDI's au smartpass service at a price of 390 Yen.
