I have put a new pack together which includes all known custom player models, all custom skins for the models and all extras. It also includes all the extras for the thug and bitch models (backpack, hats, cigar, joint etc).
There are loads of custom models both male and female. You probably know some of the more popular ones such as Homer, Mr Burns and TheMask but there are heaps of others including some crazy looking ones
The pack is 181mb.
You can download the model pack from here.
Just extract all the files to your Kingpin folder.
