You know how there are those videos at the beginning and end of each level in Halo 3 that kind of explain what's going on? Well I skipped one by mistake, and I really want to watch it, but I don't want to replay the level, because it is at the end. It is the level where you save Cortana from the Flood ship. Is there a way to access the videos without replaying the level? Or is there a website with them? Are they on YouTube?
