The '''Physgun''', or '''Physics Gun''', is a weapon cut from ''Half-Life 2'', and first shown at E3 2003. It can be found in the playable Half-Life 2 Beta|''Half-Life 2'' Beta. It is the predecessor to the Zero Point Energy Field Manipulator|Gravity Gun.

*The Physgun model is very similar to that of the Gravity Gun. The differences are some texture variations, a red wheel turning when operating in the place of the orange (or blue) glowing parts of the end of the Gravity Gun, and a beige pipe above. The gauge is very similar, and is held with the same tape in both weapons. The pincers are quite different, and simpler. However it has no worldmodel.

*Using its blue beam, the Physgun is useful when the player is unable to reach objects too far to be taken with the Gravity Gun, acting as a long range version of the latter.

*While holding the primary fire and the Use key, the mouse scroll button can bring the target towards and away from the player.

*When holding an object, its weight in pounds and kilos is shown.

*The version of its model is v35, which needs to be converted to v37 to appear.

*The Physgun's beam is also able to kill enemies and allies. It will also push Antlions extremely far.

*The Physgun's secondary fire (with a red beam) produces a Sticky Bomb-like ball (as it is the same model) that the player can use to "weld" two props together, when throwing a ball on each prop (the balls need to touch each other for the welding to work). When two props are weld together, using the primary fire on one of them will have the ball of the other produce sparks. The ball(s) of a prop will also change its color when the prop is selected. Gameplay wise, this option is very unstable and difficult to use efficiently. Sometimes the red beam will change and attach the prop to the ground after a few seconds. When the attachment is achieved, a flare sound also used by the Flare Gun and the IRifle will be heard. This feature is reminiscent of what can be achieved in ''Garry's Mod'', and hints at a possible sandbox physics feature (even multiplayer) removed from ''Half-Life 2''. Indeed, in the playable ''Half-Life 2'' Beta, the Physgun is able to perform simple to complex physics contraptions similar to those featured in ''Garry's Mod'', and without making changes to the game settings. The WC mappack map "dangerted.vmf" (named after the Citizen ragdoll present in the map, male Citizen 02, Ted Backman|Ted) for instance is a sandbox map that the team used for testing physics with the Physgun.http// Physical Gameplay in ''Half-Life 2'', page 6 Furthermore, two canister models, "W_WeldTank.mdl" and "W_WeldTank2.mdl", were apparently designed only to be weld to specific objects and make it fly away when ignited, as they contain volatile gas. They were removed from the retail files, hinting at their purpose being nil in the final game.


*The Physgun is featured in popular mods such as ''Garry's Mod'' and ''SMOD'', though both use the Gravity Gun's model for it. Its functions remain the same except that it is able to freeze objects. Another ''Garry's Mod'' feature is the ability to rotate objects.

*In the ''Half-Life 2'' files, several texture files for HUD weapon icons can be found, most of which still containing the icons for almost all of the cut weapons. The Physgun is among them.

*''Portal 2'''s version of the Aperture Science Handheld Portal Device|ASHPD has a Physgun-like functionality in the Sixense Motion Pack, a DLC available only to those who own a Razer Hydra motion controller.http// Portal 2 with the Razer Hydra on YouTube

*There are eight red bars in total that circle the main chamber on the Physics Gun.

*The beige pipe attached to the Physgun is very deceiving. While it looks like it is curved all the way over the red bars and to the front of the gun, it is actually attached on the side and curves outwards and forwards only a little, giving an illusion of it curving forward a lot.http// GM_construct0011.jpg on this Wiki

*It is possible to re-create the experience of the weld tanks in ''Garry's Mod'' by welding thrusters that look like the W_WeldTank model to a chosen prop. The thrusters must have to have the option 'Ignite when damaged' enabled for this to work.

*At first glance the HUD icon seems to be the same as the Physics Gun's model, but it is most likely not of the Physgun, but more than likely it is of an earlier Physics Manipulator model, and the HUD icon had not been changed since then.
