If you didn't stay up to catch Halo 4 on Conan O'Brien, don't worry; you didn't miss much. Team Coco didn't play a part in the game's release date announcement, which was revealed yesterday to be November 6th, but he did have a segment on his show dedicated to Halo.
There isn't much to see in the clip. The sketch itself included some witty, hilarious dialogue by Conan O'Brien badgering 343 Industries' Frank O'Connor and Kiki Wolfkill. In terms of Halo 4 gameplay, however, don't expect to see anything you haven't already seen.
The few Halo 4 things worth mentioning appear near the end of the clip. We get a sneak peek at a rendering of a hanger filled with Pelicans. It's completely textureless, but it does give us a nice look at the map. Perhaps the most intriguing part, in terms of gameplay, is a look at the battle rifle headshotting a Spartan on the Wraparound map. For those of you hardcore fans, you may notice the scope looks more rectangular.
That's the quick rundown of the video, but if you enjoy watching Conan and his crazy antiques, I'd suggest watching the nine minute clip.
