A while back I had a quick go at modding Doom 3 to turn this cutscene into a half-life style scripted sequence. Like most of the cutscenes in Doom 3, it takes control of the camera to show you something that's happening right in front of you anyway. It's a bit broken here, but I always think Doom 3 needs a halflifeification mod. Fix all the cutscenes to not be cutscenes and do the HL1 follow/unfollow thing with the scientists and security guards. Would elevate the whole thing
