En Masse Entertainment has revealed the first details of its 'Action MMO', TERA.
The game will combine action-adventure style combat with six character races, eight classes, thousands of quests, a huge array of weapons and items and hundreds of different monsters.
Players of the six races comprising the Valkyon Federation join in a struggle against rampaging monsters, demons - in a world torn apart by the gods.
As well as controlling the action, players dictate the flow of the economy.
Currently in development for the PC by Bluehole Studio, TERA will launch in Korea in summer 2010, and Western markets will follow in winter.
"TERA is a new class of MMO that combines the depth and flexibility of online PC games with the lush graphics and immediacy of console action games," said Dr. Jae-Heon Yang, CEO of En Masse Entertainment.
"Players can go beyond factions and static storylines to write the history of TERA in real time as six races learn to work together."
En Masse will demo live gameplay of TERA at GDC in San Francisco this week.
