well thats why I said a type of mod.
opfor and bshift are add ons yes but they are also treated as mods by the game tree as far as I know. technicaly they are much more than a normal mod however to the game itself anything other than vinela half life is a mod. So I mean its a type of mod. eh.. its all splitting hairs we know that CS is a stand alone game yet we also know its a mod also. CZ is more like opfor than CS by far imho.
Anyway ill see what I can find out about mods for CZ.
