Omikron: The Nomad Soul

Omikron: The Nomad Soul (known as The Nomad Soul outside the United States) is an adventure game developed by Quantic Dream, the company that would later develop Heavy Rain. Published by Eidos Interactive and released for Windows in 1999 and the Dreamcast in 2000, it is notable for being Quantic Dream's first game and featuring original music composed by David Bowie.

Players in this game initially assume the role of Kay'l 669, a police officer from the city of Omikron on the distant planet of Phaenon, who allows the player's soul to take control of his body. They investigate a series of murders and assume the roles of different characters as they learn more about Omikron and their ability to travel between bodies and dimensions.

Quantic Dream severed ties with Eidos after developing Omikron: The Nomad Soul, leading them to publish Fahrenheit/Indigo Prophecy through Atari instead.
