My cousin and I had been trying to beat the last level of Halo 3 legendary for hours to see the legendary cutscene after the credits. We battled through everything from a very pissed off Johnson to a visit from our grandparents. By the time we finally beat the level, we were both a little exhausted. I thought that I could skip the credits to go right to the cutscene. I hit the start button. We didn't see the cutscene.
