[OLD, CHECK DESC] Siobhan's Improved HL2 NPCs

This addon may cause some problems when playing the HL2 Campaign!

This addon may be compatible with some other NPC enhancement addons, and is currently experimental. Be sure to test it first. If you've found a conflict, be sure to report it in the "Bugs" thread.

I'm sure that iNPC may be compatible with this addon. If you found some conflicting issues, please report it to the Bug Reports thread.

This addon slightly improves AI, footsteps, and weapons of Default Half-Life 2 NPCs.

This is not a NPC Pack!

What it does to NPCs:

Citizens

If the NPC has no weapon, it will use different idle animations. only included for Father Grigori

Citizens will properly hold food packages and suitcases.

Weapons

Instead of using the SMG1 Reload anim, Most NPCs will use the Unused AR2 Reload animation.
Metrocops will properly use AR2 and Shotgun weapons.
Most NPCs will use the Alt-fire attack for the AR2 and the Shotgun.
Citizens will melee attack against enemies who are very close to them.

When NPCs are about to hide and reload, They will crouch-run to their spot to prevent getting Headshot.
NPCs properly fire and reload the crossbow.

Footsteps

NPCs and Players will have different footsteps, depending on the model of the entity.
Examples:
Combine soldier have soldier gear sounds as their footsteps
Citizens, alyx, barney, and some others have their footsteps changed.

Known Issues
Errors may occur in some circumstances.

To prevent conflict with multiple hooks, the "Fixed NPC Footsteps" hook will be removed.
