Halo 2 is basically the same thing as the first Halo with a few changes such as dual guns, updated graphics,etc... However I was dissapointed with the so called eviornmental damage. I thought it was going to be something like the geo-mode technology from the Red Faction games where you could blow holes in the walls but it's just being able to move boxes around. Overall, I would probably rate this game a 8 out of 10.
