Dungeon Fighter Online

Dungeon Fighter Online, known in South Korea as Dungeon and Fighter, is a multiplayer beat 'em up action role-playing game developed and published for personal computers by Neople, a South Korean subsidiary of Nexon, and originally published by Hangame in 2005. It was released in Japan as Arad Senki and published in China by Tencent, and a global version followed in May 2015. Players traverse two-dimensional screens fighting hordes of monsters in the manner of arcade hack and slash games such as Golden Axe and Double Dragon, and the game has social features including guilds, player-versus-player arenas and party play. Neople built the game in 2D and drew on belt-scrolling games for its role-playing design after dropping an early idea of a fighting game in the style of Tekken. According to Nexon, the game has more than 850 million registered users worldwide and over 22 billion dollars in lifetime revenue as of June 2023.
