South Korean gaming giant Nexon Co. is making all-out efforts for the successful launch of a mobile edition of its flagship title "Dungeon & Fighter" in China, industry sources said Tuesday.

Neople, a subsidiary under Nexon responsible for the development of the mega-hit game, has recently opened a new office in Seoul that can house more than 300 employees, they said.

Neople also recently announced a plan to newly hire hundreds of employees, such as programmers and overseas marketers, who are to be allocated for the mobile version of "Dungeon & Fighter."

"Dungeon & Fighter" was first released in South Korea in 2005 and quickly became a global hit, generating accumulated revenues of over $10 billion worldwide.

Nexon said the mobile version will be launched in upcoming summer as scheduled. Some 34 million users have made early registrations for the game so far, it added. (Yonhap)
