Friday the 13th game .PAK file help

Hello,

So I was able to unpack the .pak file from the game using the quickbms thing, and now I have all the game files in a folder. The question I am asking, is how do I edit the files so I can use the unreleased content as well as get Savini Jason? I don't plan on using this stuff online, only in offline bots...

If anyone can offer some help as to what to do next I would appreciate it greatly...

Thanks!

I need PAK File Friday the 13th. Anyone have it?
