Neople is the developer of Dungeon Fighter Online, a 2D action-based MMO which is soon to enter closed beta in North America through Nexon. The game has been in service in Korea for some time (as Dungeon & Fighter), where it has been incredibly popular, and in Japan as Arad Senki since 2006. The game borrows heavily from side-scrolling classics like Capcom's Dungeon & Dragons, and represents a different style of game than one traditionally finds in the MMO space.
In DF director Yunjong Kim's own words: "Dungeon Fighter Online is basically an action game, it's about hacking and slashing, beating the opponents and beating the enemy. It's based on a part of human nature, which is the need for violence. We think that this could appeal to anybody all over the world."
