How do I use zbot in Counter-Strike 1.6?

The best option might be Condition Zero instead of plain CS 1.6

Z-Bot works still fine with the Steam Version:

  • Download and extract the ZBot ZIP-File
  • Copy all files (except liblist.gam and commandmenu.txt) to your ...\Steam\SteamApps\\..\cstrike directory
  • In the Steam Game Library -> right click on Counter-Strike -> Properties -> Launch Options and add -dll "dlls\zbotcz"
  • Now you can run the game
