Believe Ad
From Halopedia, the Halo wiki
Believe is the second Halo TV advertisment, following on from Museum. It shows the same diorama but this time with brute figures, more of the action and also Master Chief. It hints at his demise as he is amidst a huge Brute army and being held aloft in the air by a Brute Captain. However it hints that he will die not at the Brutes hand but by his own as a Plasma Grenade is held in his hand, most likely the same one mentioned in Museum. Although, the battle was evidently won, so perhaps the Master Chief sticks the brute, and lives, as the the marine from Museum says "We knew Master Chief was still in the fight." Or perhaps that was his final battle, his last act inspiring the marines to push foward and win. This will be resolved with the release of Halo 3, or the full trailer due Sept. 14 at 2:00 P.M ET
