Template:Infobox Dungeon Fighter Online (previously released as Dungeon & Fighter in Korea and Arado Senki (アラド戦記?) in Japan), is a Korean 2D triple axis sidescrolling MMO action RPG published by NHN. The game is developed by Adrenaline Shock Studio/J Shock Studio but copyright is held by Neople Co. Ltd. (also noted as Neoples Inc.). Three versions of this game exist, all separate from one another (thus requiring separate registrations). The US version is currently in beta testing.
Dungeon Fighter Online plays like a combination of MapleStory and Teenage Mutant Ninja Turtles, similar to Little Fighter. It combines RPG elements (equipment, abilities and leveling) with action (real time fighting, jumping, button combinations and hit combinations).
