Myst IV: Revelation is an 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.
Development of Revelation lasted more than three years; Ubisoft had up to 80 employees working on the game. Musician Peter Gabriel lent his voice and a song to the game's audio; the original score was written by Exile's composer Jack Wall. Overall, reception to the game was positive; reviewers lauded the impressive visuals, sound, and puzzles. Publications such as Computer Gaming World took issue with the control scheme of the game. Revelation is the last game in the Myst series to use both prerendered backgrounds and full-motion video; the final game in the series, End of Ages, is rendered in real-time throughout.
