The following is a recreation of the 2001 headcrab model using the fast headcrab skeleton and animations, containing models that can replace both the classic and fast headcrab models.
These models have a headcrab that uses the textures seen on the brickbat headcrab model.

If you have questions related to this model (Or would like to use it in something you're going to release):
