Guys, the compression of this game is very simple, I have answered this question before, if you can search forum.
There is also google, stop being lazy:

Firstly, you're discussing warez, secondly you never pay attention to the installation of the repack you are installing so you can learn how it was compressed, compressing this game is easy. You failed to realize that the warez group had files which are foreign during installation meaning only one thing. The game files were unpacked.
First of all, you don't directly compress it because it's already compressed, the
iwd files are basically
zip files, unpack those using 7-Zip then you can now compress the game, when unpacking, all that you need to do is use ISPackZip from ISDone, that function was there for a reason it isn't there for decoration, you use that function on the data you unpacked to remake the iwd files during installation. Done, what more do you want? The just resample, remove MP files if you are not into quality, but beware the MP files are needed for special ops which can be played offline last time I checked. There audio is simply wav, apply msc.
Done, you can get a size even better than theirs.
