Warm Machine said:I think it is pretty much the same. If anything it is slightly less the quality of Halo 3 itself.
It was in engine, yes. In fact, at E3 the year we debuted the trailer we gave some behind-the-scenes presentations that ran in realtime. The demonstrators stopped the demo and flew around the environment and gave the guests up close views of the Chief's armor. There was even some objects hidden behind the hill out of view of the cinematic camera that were placed to show off some of our shader techniques.
