Bandai Namco announced yesterday that Dark Souls III’s next installment of DLC, “The Ringed City”, will be available to download on March 28. Here’s a bit of backstory on Ringed City:
At the close of the Age of Fire, as the world ends and all lands converge upon themselves, a lone adventurer descends into the madness of the earth and uncovers the secrets of the past. As players make their way to the fabled Ringed City they will encounter ancient beasts, a new cast of characters teetering on the edge of insanity, new armor, weapons, magic, and at the bottom of it all, a long lost city filled with new horrors for players to overcome.
