Apparently there were two Counter-Strike Condition Zero leaks - the Axel Gembe leak in 2003, but also CZero-KPT.rar and Czero-KPT.txt
I haven't been able to find any information at all really about the first leak - does anyone remember it?
Condition Zero leak - CZero-KPT.rar
Re: Condition Zero leak - CZero-KPT.rar
The CZero-KPT release is just a repack of anon-hl2_wmods and only contains the Single Player version of Counter-Strike Condition Zero. They removed the rest of the files that were not a working version of Condition Zero.

Ah okay thanks for confirming.
