"The Zero Point Energy Field Manipulator is not a toy, Alyx!"

―Judith Mossman speaking to Alyx

       The Zero Point Energy Field Manipulator is also known as the gravity gun in Half-Life 2. The gun has two uses. The first use is to punt object to clear out barriers or moving heavy objects. It is also used to pick up lighter objects in front of the gun with a tractor beam. However, the gun cannot affect organic materials but there are a few exceptions, such as Combine soldiers. This gun is a powerful weapon due to its two uses. Even though, the gravity gun uses physics objects for ammunition; the objects are still affected by gravity. The gun has to be reloaded after every shot fired.
