Wow. Hard to tell, but perhaps those scenes of through the window and reloading aren\'t cutscenes, but realtime renders of a specific action.... and the ammo info dissapears because you don\'t need the info during the script....
It would be nice to know for sure... I think the initial part (face closeups), and the end (after the crash) are CG for sure, but everything else could be blended realtime stuff.
