Model ported by me for Half-Life 2 about three years ago.
The original source model is by Likkez. Here is the link.

I just re-hung it on a headcrab skeleton for fun. During the development of Half-Life 1, headcrabs had butts, this is kind of like an HD remake. The model is not perfect, there may be bugs. It was made for fun and only.

Initially, the mod was uploaded only to Game Banana, to avoid any problems with questionable content. Also, the description stated that no one should upload this content to the workshop...

Steam has removed the links, so you'll have to check the veracity of this information yourself. Original model from Smutbase. Mod on GameBanana.
