Tantra Online was a free-to-play fantasy MMORPG from JoyImpact and HanbitSoft loosely based on and inspired by Hindu and Buddhist mythology. The game allowed players to select from eight classes with several sub-classes, and go on quests and fight to level up. Players could pledge allegiance to one of three deities, Brahma, Vishnu, or Shiva, unlocking special skills unique to that deity's followers, as well as setting up an ongoing battle between all three factions. In addition to three-way faction PvP, there were also solo and guild battle modes available. The game had an item shop for optional upgrades.
