New content through spring
Be sure the SpotPass feature is enabled for Fire Emblem: Awakening, as the game will be getting new (free!) content all throughout spring. Up first is "A Hard Miracle," a map available now that has a mysterious woman and some obligatory kidnapped villagers. That certainly sounds like Fire Emblem, anyway.
The downloadable maps pick back up on March 28 with "Ghost of Blade," followed by "The Wellspring of Trust" on April 11, and finally, "The Radiant Hero" on April 25. Nintendo says that more special weapons, characters, and bonus challenges for Awakening's Double Duel multiplayer are also in the pipeline as freebies via SpotPass.
Thanks for the reminder that I really, really need to pick this game up. I've been slacking.
