Halo 2 was once a game you could spent literally hundreds of hours into online multiplayer, and now because its no longer online, must rely on its mediocre single player campaign. While Halo 2 was a great multiplayer for its time, the single player campaign suffers greatly from a lot of dark empty repetitive levels with terrible syncing music. Although Halo 2 has a more interesting story line with viewpoints from the Arbiter and Master Chef, ultimately it fails as a single player experience.
