Those are all the game sprites available, I am afraid.
I came across the same problem as you. Does anybody have a clue as to how to convert this odd files? I see some zako potential here...
Inside the ISO, in the AVI folder, there is a BigActors folder, with some solace: the videos of the civilians, the terrorist complete incoming/exit sequences, the samples of two unused terrorist outfits (can't say unused terrorists, since the actresses are already among the enemies). Oh, and at some point you can apparently shoot the news anchor in the head and at the belly:
The good thing is that the game sounds are ready for use.
I uploaded the relevant files here:
