NIDA Online was a free-to-play 3D MMORPG from NIDA Entertainment and GameKiss which combined sci-fi and fantasy elements. The game was set in a land under religious upheaval, where three groups - Knights, Mages, and Summoners (who also served as the game's three basic classes) - fought for a long time over their differences, while the Artificers, an outside group, crash landed onto the scene and revealed themselves to be key to the future of the land of Nida.
The game's standout features included several different quest types and a card system for obtaining bonus items, player shops, fishing, and PvP. PvP modes were duels and PKing (with associated negative points/status afterward). NIDA Online was cancelled in May of 2010.
