I'm looking at this shot: http://bungie.net/SlideShow.aspx?path=/games/Halo&slideshow=PreXbox&slide=46 and I see the chin gun on the Pelican. I remember that once on the level Halo the Pelican set down on top if me, and I was inside the nose. The chin gun was still there, part of the model. Is there still an unused animation cue somewhere that lets the chin gun flip down, or is it just a long-forgotten artifact?
