Halo 2 - Alternate Reality Game

An Alternate Reality Game or ARG. Is a game where you are given clues on various forms of media that lead to other clues, and thus allows the player to follow a story.

Bungie (makers of Halo) is currently running one for the launch of Halo 2.
If you watch the new Halo 2 trailer currently showing at the cinema. At the end, it will give a link to www.ilovebees.com hidden in a slight flicker of the XBox website address.

If you go there you will find an apparently corrupted website with some odd code running on the server. And from the looks of things the game is set to begin in 27days, so keep an eye out and this could turn interesting.
