Physgun

Overview
The Physics Gun, or Physgun, is an experimental weapon developed by the Resistance as a counterpart to the Gravity Gun.

Unlike the Gravity Gun, primary attacks will cause a beam to expel from the weapon, grabbing onto most props it touches. After grabbing a prop, the player is able to lift the prop into the air, allowing them to move it rather freely, although this may have a few issues if the prop is heavy enough. Pressing the use key while holding a prop will freeze the prop where it is, allowing it to be touched, walked on, etc. freely without it moving, which allows the player to make psuedo-platforms at their own will.

Secondary attacks will cause small, red orbs to appear on most surfaces and props that the player aims at. These orbs can then be touched together, welding props to other props or walls, although this is somewhat buggy. Only 64 orbs can be deployed at a time.

Pressing the reload key will cause all 'weld orbs' to disappear, allowing them to be reused, and unwelding whatever props were stuck together.

Interestingly, the Physgun's beam is capably of harming NPCs, causing blood to spray out of them and killing some after a moment. Although, some NPCs can ignore it entirely. Small NPCs like Headcrabs or Manhacks will die almost immediately after about a second of exposure to the beam.

Acquisition
The Physgun can be found near the end of Sandtraps, inside of an item crate precariously placed near a cliffside. The player must be cautious when trying to grab the weapon, as touching the sand will cause Antlions to spawn, and with the weapon being so close to a cliffside, being attacked by Antlions may cause the player to plummet to their death.

Advantages
-Can grab objects from nearly any range.

-Can be used in a myriad of creative ways, such as setting up blockades, creating platforms,

-Can be used as a weapon in various ways.

-Capable of picking up objects much more easily than the Gravity Gun.

-Hacks Hoppers and disrupts Rollermines.

Disadvantages
-Can be rather wonky to use at first.

-Welding objects can be confusing at first, and is difficult to use effectively.

Trivia
Interestingly, the Physgun's beam seems to serve some of the same purposes as the Gravity Gun; it is able to spring Rollermines out of the ground and can 'hack' Hoppers by holding them, whether in the ground or in the air.

Strangely, the Physgun has no movement while the player walks or jumps, it simply sits in place.
