Myst IV: Revelation

is the fourth installment in the Myst video game series, developed and published by Ubisoft. Revelation was the first game in the series released on a DVD-ROM format; a multiple CD-ROM version was not produced as it would have taken twelve compact discs to fit the data.[1] Like Myst III: Exile, Revelation combines pre-rendered graphics with digital video, but also features real-time 3D effects for added realism.
