Halo 2 was one of the best game sequels ever made. Being the most anticipated sequel, it was the top selling original xbox game. It also had the highest amount of player online for any original xbox game. Bungie (the creaters) did an amazing job of keeping all the good parts of Halo:Combat Evolved, cutting out the bad, and adding tons of new awesome stuff. One of the coolest new feature is that you can dual weild many weapons such as the pistol, the needler, and many others.
