A Canadian newspaper in Toronto featured some new information and images of Halo 3. It seems that there are new armor types for multiplayer and a new vehicle called the Brute Chopper. I think it looks totally sexy and the same goes for the new armor. They also revealed the names and a tiny glimpse of two new multiplayer maps, Epitaph and Shrine.
