weapon_physgun is a cut point entity available in Half-Life 2. It was used by the developers to assist integration of physics into the gameplay of Half-Life 2, and later when demonstrating physics capabilities at E3 2003. The code for it was included in the Source SDK. Many entity keyvalues and settings, such as Physgun interactions, still refer to it by name, even though they should all be used in the context of the physcannon (the Gravity Gun).

Some mods, such as SMOD: Redux and Garry's Mod, use it in their gameplay.

Entity Description

Essentially a long range Gravity Gun, it could manipulate objects from afar with a fishing rod-like laser beam. Pressing the +Use key while holding an object with the beam, then using the mousewheel allows adjusting the distance to the object.

The alt-fire deploys a 'glue blob' which can be attached to physical objects or the world, working as a dynamic constraint. When a blob attached to an object enters into proximity with another blob, it will attempt to weld with it.

In Garry's Mod the Physgun can manipulate objects and freeze them mid-air, but lacks the alt-fire welding mechanics. It uses the upgraded Gravity Gun model rather than the cut Physgun model.
