Following in the footsteps of Persona 3 Social and Persona 4: The Card Battle, Index announced a social game based on Devil Survivor 2. The game takes place in the same world where the Septentrion wreck havoc on the world. Players will run into characters from the game and the anime series in Devil Survivor 2: The Extra World.
Devil Survivor 2: The Extra World is a card battling game. You form a deck with character, skill, and demon cards. Mobage will start service in early April, but registration starts now. Sign up early and you get an Io Niita card as a bonus.
