After 12 hours of anticipation, the countdown that hit Bungie's front page last night has finally clicked its way down to zero.
Once finished, the standard front page was replaced, with a news item linking to “Teaser Trailer“. And man, does it tease.
It begins by flashing through a series of what appear to be security camera (Superintendent) views of an earth city. (One of the security camera's is labeled Mbaraki, which is a location in the real world Mombasa in Kenya. A return to New Mombasa?) Something tears through the atmosphere, smashing into the city. The Halo 3 logo pops up, followed by “Prepare to Drop”.
I'm still hedging my bets on singleplayer DLC for Halo 3. Update: Yep. If you check out the video's description on the Xbox Live Marketplace, it outright says “High action and deep mystery await players in this new halo 3 campaign experience. Prepare to drop!”.
