Half Life 2
This is as you can see on the file name, a Wolf Hand skin. As the other skin that (CW) made that was for the NPC Combine, this has been made for your Hands only.
This is a rebel re-skin of the hands for Half-life 2 from Dosia36.
These are very nicely done Combine hands skins for Half-life 2. They should work in most source based mods.
