I have CS, although i've never played it because I don't want to stay up all night downloading the patch. Is CZ an expansion pack or a whole new game? Which patch should I download in order to play CS online? Where do I get it?

CZ's really just an update to CS including single-player missions. In order to play CS online, download and install Steam.
