Singularity

In this FPS, you travel across a remote island off the coast of Russia ripping through space and time, and are given your own Time Manipulation Device of which you use to vaporize enemies. You can upgrade your TMD, yourself, and weapons throughout the campaign which is reminiscent of every modern shooter from the Call of Duty Modern Warfare and World at War series to Half Life 2, and F.E.A.R. Time is power. Multiplayer included but is no longer filled with an active community.

When a strange electromagnetic surge from Katorga-12, a long-abandoned Soviet island, damages an American satellite, Captain Nathaniel Renko leads a team of Marines to investigate, only to crash-land on its shores. Once there, Renko begins slipping between the present and 1955, the year of a catastrophic accident tied to a mysterious element called E-99, and impulsively saves a scientist from a deadly fire. Returning to the present, he discovers his single act has rewritten history into a nightmare, and armed with a recovered Time Manipulation Device that can age, restore, and reverse matter, he must set right the timeline he has broken.
