Automatic Patch Downloads
Xfire can be enabled to automatically deliver you the latest patches for the games you have installed on your computer, all with a single checkbox. Xfire detects which games you have installed, and when a new patch is released, it will be begin downloading immediately over Xfire's fast, exclusive P2P network. Now you never have to worry about booting up that game you played 6 months ago and having to dig up all the old patches - just play. Hot new patch coming out? You'll get that too, as soon as it's available.
Oh, and of course, it's free.
To enable automatic patch downloads, go to the Files tab from Xfire's Tools -> Options menu. On this tab, just check the box titled "Automatically download patches for my games." That's it.
