It does look, sound, and play an awful lot like the Halo 3 we all already have on the shelf, but it also offers a great original campaign (perhaps the best the series has seen yet) and nifty new multiplayer mode called Firefight that can truly stand on their own. Of course, it doesn't hurt that ODST also includes the full Halo 3 multiplayer experience along with a Halo Reach beta invite to sweeten the deal. Is it worth $60? Oh yeah."
