A gravity gun is a type of device in video games, particularly first-person shooters using an advanced physics engine, whereby players can directly manipulate objects in the world, often allowing them to be used as projectiles against hostile characters. The concept was first featured in the third-person shooter Psi-Ops: The Mindgate Conspiracy which, while not featuring a dedicated 'gravity gun', allows the player to use telekinesis to manipulate both objects and enemies by moving them or forcefully throwing them around.
