This news comes courtesy of a 2016 preview. En Masse got a heads-up from Bluehole about incoming content for the MMO and passed it along to the players in the form of bullet points.
In addition to the super-BAMs, TERA will be getting a lot of guild vs. guild battles, enhanced guild perks, class balancing, UI tweaking, and a pair of new dungeons: the Castle of Lilith and the Ruin of Rakelith. All of this content should be arriving to the eastern version of the game by the end of the year.
In sadder TERA news, MMO Culture is reporting that China’s version of the game is shutting down for good in China. While no reason is given, the site suggests that the publisher’s lack of promotion for the game since its launch two years ago might have a little to do with it.
