This is a build of Counter-Strike Condition Zero that was leaked during the Half-Life 2 leaks of 2003. It is contained within the "Half.Life.Including.Condition.Zero.READ.NFO-ANON" (anon-hl2_wmods) archive, as "cstrike_trs". This is the multiplayer/offline with bots portion of Condition Zero, developed by Turtle Rock Studios. This build contains raw bot voices before they were processed through a radio filter. There are many maps that are different from their retail counterparts as well as many that were cut from the game.  

This custom, standalone build, was made with minimal alterations to the original content.  The only aspects that were altered, were fixing the broken GUI elements and adding one map that was not contained in the leak (cs_arcticbiolab). Any missing textures were left unfixed intentionally for authenticity.
