En Masse Entertainment officially announced its formation today, and this game publisher is comprised of veterans from some companies you may recognize: Blizzard, Microsoft, Electronic Arts, ArenaNet, and NCsoft. CEO Dr. Jae-Heon Yang was the CTO for NCsoft until 2007, while COO Patrick Wyatt was a creator of the Warcraft and Starcraft franchises, as well as the co-founder of ArenaNet.
En Masse's first official title is TERA, a next-generation MMO developed by Korean company Bluehole Studio. The game is scheduled to launch for PC in Korea this year, and En Masse is currently adapting it for Western audiences in North America and Europe for an early 2011 release. En Masse will unveil TERA next month in San Francisco at the 2010 Game Developers Conference.
TERA is a gorgeous fantasy MMO with a tactical combat system that will allow players to have a direct impact on the world through the game's political system. Players can choose from six races, such as High Elves and the Panda-like Popori, and eight classes. Check out the official TERA trailer after the jump and keep an eye on ZAM.com for more information on the game as it's revealed.
