The multiplayer isn't worth it
The controls seem fluid, and you can change them as you see fit. A lot of people I know use "Bumper Jumper" while I stick with "Standard". There is a weird thing about using meele though. If you hit an enemy's shoulder in the right place, it counts as an "Assassination", an instant kill.
Graphics- 5/5
The landscapes look very detailed, as do the Covenant, but the Marine model leaves a little bit to be desired.
Storyline- 4/5
The story is action-packed. In fact, my favorite scene was the final moment of the last mission. The only real disappointment here is the lack of a challenge once you reach the final "boss".
Replayability- 3/5
While the online mode may be fun at first, it becomes a heavily aggravating ordeal. Once you reach a rank around 20, you meet some dirtbags that we call "Derankers". Derankers make it up to a high level (>40) and then purposely lose to drop their rank to fight newer players. This is unfair wether you have one on your team or the opponents. You're either getting annihilated by them, or losing because they don't kill. This is the only reason that I dropped Halo 3's rating to 8.5. Bungie needs to better monitor its matchmaking players.
