Pickaxe replacement for crowbar
Hands and pickaxe prop by Valve
Fakefactory's world textures as a base, I just put them on the pickaxe model and added a bumpmap.
The animations used for this are from the Half Life V_crowbar model.
I've included an optional impact sound, installing this will require changing some lines in the game_sounds_weapons.txt file, instructions are included.
Not much more to say I suppose.
Have fun with it.
