After watching that, I clicked on one of the vids down the side, which included Steve Downes on a panel with Jen Taylor (which was apparently the first time he'd been in the same room with her), and they were playing the audio from when he was having goes at certain lines for H1. After some death cries which you'd recognize, the control guy asks for one where Chief has just died from a huge grenade and he's flying through the air. The attempt is pretty funny - and reminiscent of an H3 Grunt death cry for similar circumstances.
