Halo 3 has dominated the headlines and Xbox 360 disc trays for days now, but there's still something that you might not be aware of. While Bungie did a superb job on the game itself, the official Bungie website is home to all manner of information and tools that every self respecting Halo fan should be interested in.
First off, it's essential that you link your Windows Live account (previously MSN Passport) to your Xbox LIVE Gamertag. This ensures that Bungie can grab all your game data and present it for dissection on Bungie.net. Once this is done, logging into the site is like discovering a chest of buried treasure.
Titled "Halo 3 Service Record", this website-based database of information is effectively all the info you'll ever want on your time with Halo 3, be it games played online in any of the numerous multiplayer game modes or the main campaign. If you and your mates constantly argue about who the best player is during co-op games, the numbers can now speak for themselves.
