The second of the Halo 3 "Believe" ads has made its way onto the web, and it extends the story told in yesterday's ad "Museum" (now available on Marketplace, by the way). Again featuring the diorama of a gigantic battle, the ad more or less presents a freeze frame at what appears to be the defining moment in the fight. Whether or not this battle is indicative of a similar battle in the actual game, we don't know. If it is though, Halo 3 is looking to up its presentation by an epic measure. We only hope that the game can live up to the kind of drama that's alluded to in these ads. The ad appears to have been leaked early (note the bump at the beginning with the ad agency's name), so we're expecting a high resolution version soon. For now, watch the ad and share your thoughts.
