This year's annual Game Developers Conference was held in San Francisco, CA during the week of March 23-27. The developers of Atlantica Online were on hand to reveal details of future content at a press conference. Initial word came from translations of the Korean website as well as gaming news sources. But information was finally released on the nDoors website yesterday and can be found here.
There's also a flash site that has an introductory video. While the video doesn't show any new content, it does have some pretty nice Atlantica eye candy set to exhilarating music.
Pretty excited about the 100vs100 tactical battle system. If they can make it work, it should make for a pretty unique gaming experience.
