Myst IV: Revelation is a 2004 adventure video game, the fourth installment in the Myst series, developed and published by Ubisoft. Like Myst III: Exile, Revelation combines pre-rendered graphics with digital video, but also features real-time 3D effects for added realism. The plot of Revelation follows up on plot details from the original Myst. The player is summoned by Atrus, a man who creates links to other worlds known as Ages by writing special linking books. Almost twenty years earlier, Atrus' two sons nearly destroyed all of his books and were imprisoned; Atrus now wishes to see if his sons' imprisonment has reformed them. The player travels to each brother's prison, in an attempt to recover Atrus' daughter Yeesha from the brothers' plot.

Myst is a franchise centered on a series of adventure video games. The first game in the series, Myst, was released in 1993 by brothers Rand and Robyn Miller and their video game company Cyan, Inc. The first sequel to Myst, Riven, was released in 1997 and was followed by three more direct sequels: Myst III: Exile in 2001, Myst IV: Revelation in 2004, and Myst V: End of Ages in 2005. A spinoff featuring a multiplayer component, Uru: Ages Beyond Myst, was released in 2003 and followed by two expansion packs.
