Almost identical to Halo 2 just next-gen. Graphics and such feel like they were rushed
Graphics_ The graphics aren't that great. At least not for next gen. The player models for the chief and for multiplayer look good but other than that... eh. Textures are bland if you actually look and alot of the surfaces are really shiny. Maybe to mask the bad texture?
Sound_ nothing worth noting. Voice acting is good except for the Commander. She sounds forced at some points.
Gameplay_ Same as halo 2 except for equipment. Equipment are things you pick up that yoiu throw and have dif. effects. Which is Bungie's way of making it seem different. Multiplayer has barely changed either.
SUmmary_ Really. If you have halo 2 you don't need this game just get it if you want to play halo multiplayer with some better graphics.
