There looks like there’s a ton of ragdolls that could be used in Gmod. It’d probably be really satisfying to get them all converted, too.
I’ve never even heard of God Hand. Well, I have, but it’s a weapon in several Final Fantasy games that I’ve played, and I’m fairly certain that has nothing to do with this.
On a thread-related note, you should consider providing some images of what you are wanting ported to GMod. Your request as it is now is a bit vague and doesn’t really say much.
