MC knows all

halo is more a balance game so that things are fair. so that atleast when your being shot at, then u have time to react and kill the person unlike "cock of duty 4: modern gayfare" u just get instantly headshotted and die.
plus for CoD4 u cant play more than 1 person on the same console online, or co-op online OR have a forge option. halo 3 has way more features, way better gameplay, and a wayyy bigger community so face it...
