Over 2.5 million copies of the Xbox 360 exclusive Halo 3: ODST have been sold in two weeks, generating more than $125 million in sales. Not bad for an 'expansion pack'.

"With the Halo video games, game developer Bungie created a space-opera mythology for the Microsoft Xbox game systems to rival Star Wars," reports .
They also detail how Microsoft are planning to blitz fans with even more Halo goodies; more videogames, comics, videos (those anime movies), novels and even action figures.
Things don't look over for the series favourite dude, Master Chief: "I think that (his) fate, Cortana's fate and the identity of that giant, dark planet at the ending (on the game's hardest skill level) — that's a spoiler — are probably big mysteries that would be irritating if they were just cliffhangers," revealed Frank O'Connor, creative director at 343 Industries.
