npc_metropolice is a point entity available in 
Half-Life 2, 
Half-Life 2: Episode One, 
Half-Life 2: Episode Two, and 
Half-Life 2: Deathmatch. They serve as City 17's primary police force and are one of the most basic Combine enemies.
npc_metropolice uses a small arsenal of weapons and little tactical judgement, designed for the first few levels of Half-Life 2 and its authoritarian atmosphere. npc_combine_s is usually used for the Combine's actual military force.
The gordon_precriminal global state makes all npc_metropolice neutral to the player and citizens, pushing the player away when they get too close and chasing them when provoked. This is used throughout the Half-Life 2 chapter Point Insertion and works best with stunsticks.
In Half-Life 2, they serve as the Combine's thought police, collectively known as Civil Protection, and mainly use stunsticks to brutally police the citizens of City 17. They are the player's main opponent throughout the first few chapters of Half-Life 2, using explosive barrels and mounted guns to their advantage and disadvantage, but they're eventually replaced with npc_combine_s and disappear until the chapter Anticitizen One, where they again function as the main Combine enemies for most of the chapter.

| Cvar/Command | Parameters or default value | Descriptor | Effect |
|---|---|---|---|
| metropolice_chase_use_follow | 0 | arbitrary number | Causes pre-criminal npc_metropolice with stunsticks to follow the player indefinitely. |
| metropolice_move_and_melee | 1 | arbitrary number | Makes agitated npc_metropolice activate their stunsticks right as they begin to swing, as opposed to stopping for a moment to activate it once they successfully navigate to their target. |
| metropolice_charge | 1 | arbitrary number | Toggles whether npc_metropolice with pistols charge at the player. |
| sk_metropolice_health | 40 | health amount | npc_metropolice health when spawned. |
| sk_metropolice_simple_health | 26 | health amount | npc_metropolice health when the Simple cops flag is checked. |
| sk_metropolice_stitch_distance | 1000 | hammer units | Distance that npc_metropolice will begin to attempt stitching. |
| sk_metropolice_stitch_reaction | 1 | arbitrary number | Multiplier for the amount of time shots in the stitch line travel from their starting position to the player. Fractions make the npc go through the stitching behavior multiple times, and values above 1 make the stitching slower.
Bug:0 will make the game freeze the moment stitching is attempted. [todo tested in ?] |
| sk_metropolice_stitch_at_hitcount | 1 | arbitrary number | Number of times a stitching npc_metropolice is allowed to hit a player. Due to random bullet spread, the result may be slightly more or less. |
| sk_metropolice_stitch_behind_hitcount | 3 | arbitrary number | Number of times a stitching npc_metropolice is allowed to hit a player while behind the player's airboat.[confirm] |
| sk_metropolice_stitch_tight_hitcount | 2 | arbitrary number | Number of times a stitching npc_metropolice is allowed to hit a player while aiming directly at the player's airboat.[confirm] |
| sk_metropolice_stitch_along_hitcount | 2 | arbitrary number | Number of times a stitching npc_metropolice is allowed to hit a player while alongside the player's airboat.[confirm] |
Flags
BaseNPC flags
Note:This flag is disabled in episodic for player companions, because the
Wait Till Seen : [1]
- Prevents this NPC from seeing (or being seen) until it enters a player's viewcone.
Gag : [2]
- Won't make IDLE sounds until it's angry.
Fall to ground (unchecked means teleport to ground) : [4]
Drop Healthkit : [8]
- Causes this NPC to drop an item_healthvial upon dying.
Efficient : [16]
- Don't acquire enemies or avoid obstacles
Wait For Script : [128]
- Forces this NPC to "wait" in an idle state until it finishes playing a scripted_sequence.
Long Visibility/Shoot : [256]
- By default, increases a NPC's sight range to
6,000units and allows it to attack from anywhere within that distance.
Fade Corpse : [512]
Think outside PVS : [1024]
- Allows this NPC to run its regular AI outside of any player's PVS.
Template NPC : [2048]
- Marks this NPC as a template for entities like npc_template_maker. The NPC will not spawn on its own. This is not needed for point_template.
Note:This flag is disabled in episodic for player companions, because the StartScripting input does this.Don't drop weapons : [8192]
Ignore player push : [16384] (in all games since 
)
- Entity won't give way to player.
Note:If the efficient flag is checked, then the model of the NPC becomes models/police_cheaple.mdl.Simple cops : [131072]
- Sets the NPC's health to the value of
sk_metropolice_simple_healthinstead ofsk_metropolice_healthand enables more dramatic flinch animations. Used in the early canal levels of the game.
Rappel : [262144] 
- Deprecated.
Use the "Waiting to rappel" keyvalue instead.
Always stitch : [524288]
- This forces the stitching behavior to occur. If the npc_metropolice is armed with an SMG and the player is beneath them, they will shoot a meandering, closing path of bullets (like the first metrocop in d1_canals_07.
No chatter : [1048576]
- Automatically gags the NPC and supposedly prevents some metrocop-specific speech that standard gagging doesn't. This is now believed to be non-functional.
Arrest enemies : [2097152]
No far stitching : [4194304]
- Stops stitching if the player is over 6000 units away. Note:That's about the distance between the two forcefields on the bridge in d2_coast_07.
Prevent manhack toss : [8388608]
- Prevents the NPC from deploying their manhack(s). See the
EnableManhackTossinput.
Allowed to respond to thrown objects : [16777216]
- In pre-criminal mode, allows the NPC to chase players who have annoyed them. If this flag isn't enabled, they will call for the nearest available npc_metropolice to chase the agitator. This also occurs if the NPC is using anything other than a stunstick. This does not override the settings of an ai_goal_police.
Mid-range attacks (halfway between normal + long-range) : [33554432]
- Extends the NPC's preferred attack distance to 3500 units.
Keyvalues
- Weapons (additionalequipment) <choices>
- What weapon this NPC should spawn with. Choices are:
- weapon_pistol Note:With this weapon,
npc_metropolicewill periodically take a couple steps toward the player if they can path to them. - weapon_smg1
- weapon_stunstick
- weapon_shotgun
Warning:The default model (police.mdl) doesn't have proper animations for this weapon. - Nothing
- weapon_pistol
- Number of Manhacks (manhacks) <choices>
- Allows a npc_metropolice to carry up to two manhacks on their right shoulder.
Bug:If the player gets to about melee distance from a npc_metropolice while they're deploying a manhack, they may be interrupted and the manhack be stuck on their hand until the npc_metropolice dies, after which it will deploy normally. [todo tested in ?]- Pistol starts drawn (weapondrawn) <boolean>
- Whether or not the pistol should start unholstered. The pistol can only be unholstered when the NPC spots an enemy, and inputs like
UnholsterWeaponhave no effect. This keyvalue has no effect on other weapons.
Bug:If the pistol has not yet been drawn and the npc_metropolice must attack during a scripted behavior such as an assault or scripted_sequence, they may skip drawing their weapon and use an invisible gun. [todo tested in ?]RappelNPC:
- Waiting to Rappel? (waitingtorappel) <boolean>
- If yes, this NPC spawns suspended in air and awaits a
BeginRappelinput. It will then spawn a zipline and slide down. When it hits the ground, NPC will cut away the line and try to move forward a few feet to make room for the next NPC. The NPC will not attempt to clear its landing space if it cannot do so by taking a few steps forward.
