From a score of eight to 9.8 out of 10, it seems the critics like it. Phrases such as "awesome", "out-Bungie Bungie" and the words "343" and "nailed" in the same sentence.
Video with Jen Taylor, the voice of Cortana. She does all the narration in the video and it is a bit weird to hear "Cortana" talking about Halo.
Copy of the Live Stream with 343 and Major Nelson. One and a half hours with Infinity multiplayer.
