Singularity

The game takes place in 2010 and the plot revolves around a mysterious island known only as "Katorga-12" where Russian experiments involving "E99" (Element 99, which appears to be an equivalent to the actual element Einsteinium, which has no special properties like those referenced in the game), took place during the height of the Cold War era. Sometime during 1950, a terrible catastrophe known as the "Singularity" occurred on the island. The player controls Nate Ranco, an Air Force pilot who is sent to investigate bizarre radiation emissions coming from the island only to crash land there. After regaining consciousness, he finds the TMD (Time Manipulation Device) and discovers that the island is constantly shifting between the time periods of 1950 and 2010. Renko's goal is to find his co-pilot, escape the island and eventually prevent the Singularity.Besides having to deal with hostile Russian forces in both time periods, the player must also deal with hideously mutated flora, fauna and former residents of the island, some of which have actually developed time manipulation powers of their own
