Dungeon Fighter Online

Dungeon Fighter Online (previously released as Arado Senki (アラド戦記) in Japan and Dungeon & Fighter in Korea), is a 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.

You will probably will have to figure out most of the game unless you check out this guide. 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).
