Kalonline is a hardcore Korean Fantasy MMORPG developed by Inixsoft. Based on Korean mythology, the game is a standard MMO wherein players can choose between one of four character classes as their character. These classes are then leveled up via the slaying of monsters. Each class has 6 jobs (or government positions) that players can work their way through — each with their own skills. Unlike other MMOS, players are encouraged to change jobs several times in order to build the best skill set — rather than choosing one and sticking with it. In addition to regular quests, Kalonline also features varying types of PvP, including: Castle Siege, tower defense, and more. Players can join guilds, which require six players to create. Kalonline was originally released in 2004 and was made available via Steam July, 2016.
