Gravity is a funny thing. Apparently, this force of nature is also the final TMD attack in Singularity. The latest Time Manipulation Device vignette puts the total at four unique abilities, from Age/Revert to the time-stopping Deadlock.
Gravity basically allows you to control objects from a distance. The video demonstrates our American hero diverting a missile with the TMD, sending it back into the shooter's face. Nate also ganks someone's shield, then holds it out in front of him for protection.
