HOWEVER, the downside to that is due to a copyright claim in Europe, the EU version will henceforth be known as Shingeki no Kyojin: Humanity in Chains, and is currently delayed. We don't have an exact launch date yet, but we're shooting for as soon as possible. Stay tuned for more info!
BUT WAIT JUST A MINUTE! Everyone who purchases Attack on Titan: Humanity in Chains or Shingeki no Kyojin: Humanity in Chains will receive a unique Attack on Titan theme for Nintendo 3DS FREE. This theme will not be available for purchase separately, it's only available by purchasing the game. (But as you correctly inferred, this means both the Americas and Europe will receive the theme!)
Now that the business is out of the way, on to the fun! We have a brand new character trailer for the characters you can play as in Attack on Titan! From the greenhorns like Eren Jager and Armin Arlet to the experienced Levi, the captain of the Scout Regiment, players will be able to step into the shoes of their favorite character and relive the plot of the anime!
We have a brand new trailer to show off the characters as well, which you can find here and post immediately!
