A snippet of this month's The Secret World newsletter hints at a dungeon that is in development that will "contain interesting challenges" for players. According to the post, bosses will utilize Aegis tactics and heretofore unseen ways.
In addition, players can look forward to a Nightmarish version of the New York raid that will see new loot as well.
The team has plans to share more about the v12.5 update during special live stream events.
