What Models Do We Have?
I’ll constrain the scope here to HL2’s modelsources - there is more than this, but there is no clearer case where we know what we don’t have. Where multiple releases have occurred, I place them top-to-bottom. This means more completed releases will generally be near the bottom.

Gmod animations can be found here.
Color guide:
- Fully available (according to my knowledge).
- Incomplete sources available.
- Compiled versions available.
- Only indirect sources / pictures.
- Unknown and unavailable.
