Devil Survivor 2 wasn’t released in Korea, but the expanded 3DS version will. Nintendo of Korea is localizing and publishing Devil Survivor 2: Break Record in the region.
Atlus and Nintendo of Korea have had a strong partnership ever since Shin Megami Tensei IV. Etrian Odyssey Untold and Persona Q: Shadow of the Labyrinth were published and localized by Nintendo of Korea too. Other games like Etrian Odyssey IV weren’t localized in Korean, but were distributed in English and Japanese via the Nintendo eShop as digital imports.
Devil Survivor 2: Break Record is slated for release in North America in early 2015. South Korea will get the game in 2015 too.
