Attack on Titan 3DS has free Levi story mode DLC

But it's only free for a limited period of time.

Attack on Titan: The Last Wings of Mankind will come with playable story modes for Eren, Mikasa, and Armin. And for a limited time after launch, you’ll be able to download an additional story mode for Levi free of charge.

When you clear Levi’s story, you’ll be able to use his character set and unique weapons in World Mode, in which you create your own character and can play four-player co-op with friends.

Attack on Titan: The Last Wings of Mankind launches December 5 in Japan.

Thanks, Famitsu.
