Halo 3: ODST is the most unique Halo entry. It was the first Halo game to not have Master Chief as the main protagonist, nor did it have a traditional multiplayer mode the series had been known for up to this point.

Nevertheless, it succeeds with a bleak and emotional single-player campaign, the best soundtrack in the Halo series, and the addition of the amazingly addictive Firefight mode. It has become one of my favorite video games of all-time.
