Halo 2 is one of the best FPS games. The great multiplayer aspects overwhelm the good but short single player game.
The multiplayer is very familiar and has many new features to go along with it. The controls are the same but with a few new features in the game comes more controls to learn. A few of the new features are dual-wielding, vehicle hijacking, and of course online capabilities. The new dual-wielding aspect of the game is basically being able to hold and shoot 2 one-handed guns at the same time. This feature obviously will allow players to kill thier opponents much faster. Vehicle hijacking is self-explanitory. You can steal vehicles from other players in multiplayer. This is very useful in online games. You can also throw grenades into tanks to removes your enemies from them. The Xbox Live setup for Halo 2 is very well done. Bungie was definately thinking of options when they made the online capabilities. Bungie also incorporated the use of clans. Clans are groups of people online that have matches together. The ranking system is very much like that of an RPG leveling system. For instance if you are just begining you will only play people that have the same level as you. If you beat people that have a higher level than you you get more expirience than if you were to beat someone that has a lower level than you.
Halo 2 is a great game. The multiplayer is the best of it's time since Goldeneye: 007(N64). The online options and capabilities are the most numerous that I have seen in any Xbox Live game. Halo 2 is a very good game and I'm sure Bungie will continue to go in the right direction with this soon to be gaming dynasty.
