With Halo 3: ODST you get the most story-driven Halo campaign yet; one with a great atmosphere and the best Halo music score to-date. The graphics engine is showing signs of its age, and the cut scenes are inexcusably bad, but ODST brings something new to the series with its atmosphere and VISR art style. You also get the complete Halo 3 multiplayer experience thrown into the mix. However, it's Firefight that seals the deal. Even if you already own Halo 3 you're going to want to check this mode out; there's no matchmaking system for it though, so you will need Halo friends, which isn't something we all have, but if you're a Halo fan with friends you don't want to be left out now, do you?
