Counter Strike: Condition Zero is available for download using BitTorrent from BitTorrent Movies (www.bittorrentmovies.de). The site is in German, but its easy enough to navigate even if you don't know any German.
I think its an image file due to the size.
Well, if you don't know how just do this:
Go to bittorrent movies.
Look at the navigation bar down the left hand side of the screen.
Under Content, there is PC spiele (Alle), click Action under that.
A list sould come up, showing things under letter in alphabetical order.
Click the Condition Zero one.
Another screen should come up, scroll down abit then click Counter Strike: Condition Zero (Englisch).
From the Englisch, I'm guessing this is in English
If you already know this or your gonna say about the CZ bundled with Half Life from suprnova, then good for you. I'm posting it for the ones that don't know about it.
Once I've downloaded it, I'll post hash in verifieds.
