models/humans/group01/female_06.mdl	Female 5	Naomi. Caucasian wearing a blue suit.

models/humans/group01/male_cheaple.mdl	Cheaple Male 1	Low-detail caucasian wearing a blue suit. Only works if Type is set to Default or Downtrodden. (Otherwise you will just get the "ERROR" model.)
models/odessa.mdl	Odessa. DO NOT USE.	Colonel Cubbage. Only works if Type is set to Unique. (Otherwise you will just get "ERROR" in-game.)

If citizentype is set to 1 (Downtrodden), these are the models used. Other values cause the equivalent models from models/humans/group02/ (for 2 - Refugee) and models/humans/group03/ (for 3 - Rebel) to be used. The clothing changes appear only in-game, and not in Hammer.

Clothing descriptions apply for group02 only.

If the Medic flag is set and the citizentype (Type) is set to 3 (Rebel), the equivalent models from models/humans/group03m/ are used.

If you set model to something else than the default model value ( eg. Male 02), to something like (models/alyx.mdl) and disable random faces in flags, you can override the model inside the game. Note: you might need to set type to unique.

• Expression Override

<string> Facial expression override

• Fire Output When Nav Is Blocked?

<boolean> Set keyvalue to either Yes or No

• Template:Ep1 add

<boolean> A permanent squad member cannot leave the player's squad unless killed or explicity removed by entity I/O. Only use this if you're sure you want to override the default AI.

• Template:Ep1 add

<string> If you want your citizens to squad with the player but not obey commands the player gives to move the squad, put a concept here and this citizen will speak the concept instead of obeying the order.

Flags

• Template:Fl basenpc

• 65536 : Follow player on spawn

• 131072 : Medic

• 262144 : Random Head

• 524288 : Ammo Resupplier

• 1048576 : Not Commandable

• 2097152 : Don't use speech semaphore. Template:Ep1 add

• 4194304 : Random male head

• 8388608 : Random female head

• 16777216 : Use RenderBox in ActBusies.

This makes the collision hull surround the model rather than using the human hull. It's more computationally expensive, but necessary when ActBusies involve close proximity to other props/geometry or animate the citizens in a more dynamic way.
