As 2012 is nearing its end, Dengeki Playstation and Famitsu revealed some information about the update coming in January.
Our next update will add a new field which is also known as the "Darker's Den," though its official name was not mentioned yet. In here, you can fight Falz Hunar outside of story mode. When you meet a certain condition and start a quest, occasionally you'll be forcefully transferred to this new field. Anyone in the party who completes this quest could have their character's appearance and equipment cloned and turned into enemies known as "Imitation ARKS" or ARKS Clones. If you defeat these clones, you'll receive an exclusive drop. Aside from that, Falz Hunar will also appear in a city Emergency Quest.
