Ok, I thougth that it might be time for me to contribute a little to the FreeSteam Community.
This is my first Tutorial ever so please go easy on me guys!
This is just one of the ways to make the games work.
So here is a small TUT on how you can get the GCF’s to work.
First you’ll want to download Steam from the Valve website, and open a blank account (Account without games).
Next grab the FSC from FreeSteam.org (make sure it’s the latest Version!). Using the FSC download a Steam Cracker. (I use the P3ng3l Steam Launcher).
Now Find the GCF file of the game you wish to play. Place that file in your steam Apps folder.
Now open the p3ng3l launcher and then open Steam, Login and enjoy.
