"Uru: Ages Beyond Myst is an adventure video game developed by Cyan Worlds and published by Ubisoft. Released in 2003, the title is the fourth game in the Myst canon. Departing from previous games of the franchise, Uru takes place in the modern era and allows players to customize their onscreen avatars. Players use their avatars to explore the abandoned city of an ancient race known as the D'ni, uncover story clues and solve puzzles.
Cyan began developing Uru shortly after completing Riven in 1997, leaving future Myst sequels to be produced by third party developers. Uru required five years and $12 million to complete. Uru was initially conceived as a multiplayer game; the single-player portion was released, but the multiplayer component, Uru Live, was delayed and eventually canceled. The online video game service GameTap released the multiplayer portion of Uru as Myst Online: Uru Live in February 2007, but the service was canceled again the following year due to a lack of subscribers. GameTap passed the rights to Uru Live back to Cyan, who announced their intention to resurrect the game.
Uru was not as well received as previous Myst titles. Critics admired the visuals and new features of the game but criticized the lack of multiplayer in the retail version and clunky controls. Uru sold poorly, while the first three games had sold millions of copies each. The game was a critical and commercial disappointment for Cyan, causing the company financial troubles; nevertheless, it has attracted a cult following.
