No Manual - Raven Software's Singularity pits fans of first-person shooters and sci-fi against a devastating fracture in time. As players attempt to unravel a conspiracy, they must fight their way through an ever-shifting environment, haunted with time-ravaged creatures and mysteries, while sudden time waves hurl them back and forth between battles with Soviet soldiers in the 1950s and the present day's elite forces. Use wits and the perfect weapon for the job - the Time Manipulation Device (TMD) - to unravel the conspiracy behind this timeline calamity and prevent its catastrophic spread.

Clues are plentiful as time waves thrust the player between intertwined eras while attempting to unlock the secrets of a mysterious conspiracy.
