The orange suited model is well appreciated for being acknowledged in this content, however it differs from the actual ingame alyx zombie model.

An idea to implement the true thing would be slapping the orange zombie worker model's textures onto a combine worker model to get the true textures. Some edits such as removing the blood stains will be required, however there are no damages on the model which require any complicated remodellin such as an open chest.

There furthermore is a female infestation control model as a zombie.
