Dungeon Fighter Online, also known as DFO, is a multiplayer PC beat 'em up video game developed and published by Neople, a South Korean subsidiary of Nexon, and originally published by Hangame in 2005. The game was originally released in Korea as Dungeon & Fighter (던전앤파이터) and in Japan as Arad Senki (アラド戦記 Arado Senki, lit. War Records of Arad). In China, the game is published by Tencent. In 2014, Neople began an alpha test of a global version of Dungeon Fighter Online using the last English version hosted by Nexon, which has since ended.
