Add bones to Duke Nukem model

I like Duke Nukem games and recently i have found Duke Nukem HRP model pack. But there is no any ragdolls inside. After some decompiling work, i have removed RPG from his hands. But i don’t know how to make ragdolls. I mean, i don’t know how to make and assign bones. I’ve used MilkShape 3D.
Here’s screenshots:

So, i need someone, who can add HL2 bones and then i’ll make PlayerModel and NPC :smiley:
