Microsoft has released a new trailer and set of screenshots for Halo 4 at E3.
The live-action trailer depicts a speech from the head of the U.N.S.C., which turns haywire during the middle, when an ancient evil returns. The last thirty seconds of the clip are all gameplay footage.
Halo 4 is due for Xbox 360 in November. View the screenshots at the gallery. Watch the trailer below.
