A great shooter, but nowhere near as good that most people say it is.
Gameplay- Standard run and gun fare. They spice it up with some new weapons, and vehicles, like the submachine guns and the ability to dual wield smaller weapons. They also added a new variation of the warthog.
Graphics/sound- At the time the graphics were pretty good, but there were certainly better games around in that department. The sound is good, the weapons sound, good and so does the score.
Value/Fun- The campaign was decent, and I thought the multiplayer was freadful, just way to repetitive. Halo 2 is a must buy because its so damn epic, but dont expect a half life 2 like experience.
