Dungeon Fighter Online is Launching on June 9th. The game is developed by Nexon’s Neople studio and is a 2D Side-Scrolling Hack and Slash MMO in which layers fight their way through dungeons, either on their own or in a party with up to three other players. Advanced players can also take part in intense player-versus-player competition, where each opponent can mean a wholly unique fighting challenge. Dungeon Fighter Online will of course be completely free to play for all you beat ’em up junkies out there.
