Players in DK Online take on the role of Dragon Knights to fight off the terror of the ancient dragon Kharvag. When they're not busy duking it out with an ancient menace, players can hone their skills by beating each other senseless in one of the game's PvP modes. With the launch of closed beta, a new PvP mode has been opened up: Castle Siege is a contest between several guilds, with total domination as the ultimate goal. Skip below the cut for a video preview of Castle Siege.
Aeria Games is promising an "avalanche of special events" during closed beta. The game can be downloaded from the official site.
