The Exiled Realm of Arborea (officially abbreviated as TERA) is a 3D fantasy themed MMORPG developed by Bluehole Studio. The game was launched and published in South Korea on January 25, 2011 by Hangame, in North America on May 1, 2012 by En Masse Entertainment and in Europe on May 3, 2012 by Frogster Interactive Pictures with open and closed beta testings taking place before the launch dates. Possible localizations for other regions have been mentioned, but have not yet been confirmed besides Japan.
TERA has typical MMORPG features such as questing, crafting, and player versus player action. The game's combat uses a real-time battle system that incorporates third person camera view. The player targets an enemy with a cross-hair cursor rather than clicking or tabbing an individual opponent (which is called the "Non-Target battle system" by the developer). The Players need to actively dodge enemy attacks. A keyboard and mouse or a control pad can be used to control the character.
