This page lists all NPC entities and their associated model files. This is intended to be a reference for scripted_sequence where animations are stored in the model files.

There's also the Body and Skin columns which denotes how entities handle such keyvalues if given by mappers.

Notes

1. For what direct value support means, and how to calculate the values, consult Entity Programming - Introduction to Entities with Animated Models#Low-level animation control and skip to the part where body and skin are discussed.
2. The paths are relative to their respective mod folders relative to Half-Life executable:
   • Half-Life = valve/
   • Half-Life: Opposing Force = gearbox/
   • Half-Life: Blue Shift = bshift/
3. The models in the expansion packs generally have extra animations not present in Half-Life.
4. Dead monsters usually has an enumeration of pose values.
5. Applying dead poses to living monsters with scripted_sequences usually don't actually make them dead. Best to use env_sprite or monster_furniture for that.
