Atlus USA is looking into localizing Attack on Titan: The Last Wings of Mankind for the Nintendo 3DS, based on the popular manga/anime. All we know is that Atlus is bringing it to Australia thanks to the Australian Classification Board.
The Japanese publisher Spike Chunsoft has said that they will be re-releasing an enhanced version in Japan this December, this version would include online multiplayer. Since the listings for the Australian version does mention ‘online interactivity’, its safe to say that they are going to be releasing the enhanced version.
Seeing as how Atlus will need to translate the game to release it in Australia, don’t be shocked if a American and European release date are announced as well.
