Singularity is a 2010 first-person shooter survival horror video game developed by Raven Software and published by Activision and released for Windows, PlayStation 3 and Xbox 360.

The TMD can move an object backwards or forwards in time, attract something and hold it indefinitely, or send a pulse of energy that can stun or kill enemies.

The game begins when an electromagnetic surge from an uninhabited island called Katorga-12, once held by the Soviet Union, damages an American spy satellite.

Based on a journal the group found on Katorga-12, Mir-12 believes that Renko can put an end to Demichev's reign using the Time Manipulation Device (TMD) developed by Victor Barisov.

A post-credits scene shows a wounded Kathryn, pulled into 1955 by a time distortion, writing the Mir-12 journal which will later be used to track down Renko.

[6] According to Keith Fuller from Raven Software the game had a troubled development and was almost cancelled by publisher Activision.

[7] The number of development teams at Raven was reduced to one after more layoffs in October 2010, after delays with Singularity; as many as 40 staff were released.

[33] Destructoid praised the Xbox 360 version, stating that "Singularity is a game that manages to feel like its own thing despite being pieced together from previous FPS games, and if you want a great Summer shooter full of violent toys and silly super powers, then you won't get much better than this.

"[11] IGN was not so enthusiastic, and said that while "the gunplay is solid and there are a few memorable set pieces", the game is "ultimately limited by a lack of imagination where a neat time-manipulation idea is handcuffed to a by-the-numbers first-person shooter".

Club gave the Xbox 360 version a B+ and said that "for a game released to little fanfare, one that's innovative only in an additive sense, Singularity is worth playing for its canny incorporation of the best ideas from the last decade of first-person shooters, and for providing a suitably chilling atmosphere in which to enjoy them.

"[29] The Daily Telegraph gave it seven out of ten and said of the game, "With its varied combat, ridiculous story and outlandish weapons it's a fun and engaging title and it's a real pity that that Activision haven't given it the attention it deserves.

"[28] Metro UK similarly gave it seven out of ten and said it was "A little undercooked, but this is still an enjoyable attempt to create a more cerebral shooter in the vein of BioShock and Half-Life 2.
