TERA has surpassed 1.4 million player accounts according to En Masse.
TERA made the free-to-play switch in February and has since added additional servers, a new dungeon, and a PvP battle arena. En Masse is celebrating its uptick with an in-game event called Dracoloths Rising. From March 20th through March 24th, even bigger big-ass-monsters are roaming the wilds of Arborea and serving as loot pinatas for opportunistic adventurers.
