Halo 2. Yay!!!
The story, is... pretty good. The beginning is good, but the ending... is just awful! If you finish the game, be ready for something awful. Something that will annoy you.
The gameplay is about the same as Halo 1, only will some tweaks. First, you can take enemy vechiels. Second, you can duel-wield.
There is some new weapons, like the Energy Sword (which is SWEET!), the Fuel Rod Cannon, and, other stuff (I think...). One thing you'll notice that there is no Assualt Rifle. It was in Halo 1, but not in Halo 2!
I'm going to skip my graphics review. We all know that the game looks good.
The AI is, depending on the difficulty, easy to impossible. There is Easy, which is a walk in the park. Normal, is OK, but not really hard. Heroic, is hard. Legendary, is HARD! It will beat you down! Hard!
