Twelve Sky was a free-to-play, martial arts-based MMORPG from Alt1 and Aeria Games. Set in ancient China, Twelve Sky put players in the middle of a conflict between the three warring factions of Guanyin, Fujin, and Jinong. Players could choose a faction and engage in PvE and PvP content with a large variety of authentic martial arts weapons, thousands of unique items, and an elaborate weapon and armor enhancing system. The game featured a solo- and party-friendly battle system with combat that allowed players to hit different body parts of their opponents. Factional PvP was also a main focus of Twelve Sky. The game was shut down in April of 2010, and has been succeeded by its sequel, Twelve Sky 2.
