As Bungie announced in the
lame strategically timed early-morning web update, Master Chief will appear in a Halo 3 commercial during tonight's Monday Night Football. Today also signals the registration frenzy to try to score a slot in the Halo 3 public beta (a.k.a Pimps at Sea); check the Halo 3 site for details. (The site wasn't yet updated when this post went live, but we expect a "many will enter, few will win" scenario.)
The 60-second commercial will air on ESPN sometime between 5:50 and 6:20PM PST in North America. The rest of the world can download the commercial at Xbox.com beginning at 9:00PM PST (04.00 GMT). The ad is a mix of live and computer-animated footage, but it won't include any in-game shots.
Only North American gamers are currently eligible for the Halo 3 beta. [Update: Direct from Bungie: "Don't panic. The Halo 3 Beta will be available in the US, Europe and elsewhere in the world." Thanks, Matt and azesino!]
