MS began their E3 showing with an extended gameplay montage of Call of Duty: Black Ops. The shooter is slated to take place in Vietnam. In the levels we saw, there were loads of cave sneaking and comabt, as well as an attack on a helipad. Aerial combat which is a first for the series was also demonstrated, with the main character fighting others from his chopper.
Stay tuned for more E3 info.
