Weapon Parts Overhaul documentation (by Grok):

Weapon Parts Overhaul changes the way guns are repaired, maintained, and how they jam.


What WPO does:

- New gun disassembly mechanism:

	- You can now remove gun's parts without "disassembling" (and thus destroying) it. Hold Alt and right click on the gun > Field Strip it. Only the weapon barrel cannot be removed, but everything else can be.
	- Weapon's barrel can be obtained by disassembling a gun the classic way (drag and drop Multitool on the gun holding Alt key).

- New gun parts replacement and repair system:

	- You can now replace gun parts by drag and dropping parts on a gun. 
	- Drag and dropping parts depletes condition above 60%. Less is drained if a multitool is used.
	- Gun barrels need to be replaced the classic way at the vice using the appropriate tool.
	- Using the vice and the appropriate weapon repair toolkit doesn't consume toolkit uses.
	- Gun parts can only be repaired from 60% onward using the appropriate part repair tool (Multitool, Ramrod, etc).
	- Appropriate gun repair toolkits can be used on a gun to clean it as well as increasing the lowest condition part to 100% automatically. Right click on the Repair Tool > Use. Select the desired gun.

- New gun maintenance system:

	- Gun condition now represents how clean or dirty a gun is, now how destroyed it is. Gun condition and parts condition are now separated.
	- Guns condition is now easier to maintain with items cleaning them from a lower condition and that clean them for more condition at each uses.
	- Guns are cheaper to clean at mechanics (Repair / Upgrade Item option, top right corner "Repair"). Mechanics will only clean the gun, not repair the parts.
	- Guns get dirtier quicker under the rain.

- New gun jamming system:

	- Guns will jam based on parts condition as well as clean condition.
	- Different jams require different type of unjamming. Most unjamming can be performed by unjamming the weapon.
	- Unjam by default is double-tap Use. If you are not sure, check scripts/clear_jam.script.
	- New "Unjam" key introduced. Set it in the keybinds option menu. Press the key to unjam the gun.

- Gun acquisition flow, i.e. how WPO impacts your playthrough.

	- Overall, WPO allows to use bigger guns quicker in a playthrough by allowing easier gun cleaning and parts replacement.
	- Most guns that are dropped by Stalkers are usable, but don't trust them too much : they can jam pretty often if parts are in bad condition!
	- The parts repair / tetris can be avoided by spamming gun repair kits on a given gun.
	- WPO makes parts hunting more engaging.
