Dungeon Fighter Online transports Players into the mystical realm of Arad where dangerous dungeons abound. Gamers battle monsters as an individual explorer or team up to journey through exclusive MultiPlayer dungeons. Players can choose from five distinct character Classes (Fighter, Gunner, Mage, Priest, and Swordsman), each featuring a unique set of abilities and powerful attack combinations. Each class further specializes in four sub-Classes, which opens up further skills and customization. Dungeon Fighter Online also allows Players to challenge each other in a Player-versus-Player arena where Players can sharpen the ability to customize their fighter for endless matchups with other warriors.
