Singularity’s main gameplay device is an artifact known in the game as the TMD (Time Manipulation Device). This device is powered by a very small E-99 core, and can manipulate timespace on a virtually limitless scale. 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 even kill enemies. The only weakness is that the TMD powers can be applied only to living beings or objects that have been in contact with E-99 (supposedly, almost everything on Katorga-12 is imbued with the element, but in practice, the TMD can only affect a limited set of objects like certain types of crates, tape recorders, barrels etc.). Some living beings, like the Spetsnaz Elite troopers who are covered in a heavy armor designed to repel E-99, are immune as well.
The TMD can also be used in conjunction with special power stations scattered across the island that greatly amplify its power. In some instances, the player can use this to restore entire ruined buildings or wrecked ships to their pristine state in order to progress. However, these major alterations are highly unstable and will begin to revert almost immediately, forcing the player to dash through the restored structures as they start to decay and collapse around him.
