RF Online

RF Online, which stands for 'Rising Force Online', is a Korean MMORPG that was developed by CCR, and published by Sega in Japan and Codemasters in the United States and Europe. It is a mix of fantasy with science fiction elements and is based upon a three way race versus race versus race system (RvRvR) where the three races of the game do battle through mass player versus player (PvP) battles known as Chip Wars. Originally, RF Online was subscription based. However, within October 2007, RF Online became free-to-play, with the addition on an online cash shop where real money can be spent on in-game items.
