Best Game Ever!
The thing that makes this game so strong is the storyline. It really isn't just another shoot-em-up FPS; it combines the special abilities of your character with all kinds of different weapons which you must use together to defeat a wide array of enemies. It never really gets old! The graphics are also great in my opinion, but what really adds effect is the music. When I bought the game it came with the soundtrack, and even today I consider that some of the best in-game music I've ever heard. It gives a feel to the game that simply completes the whole experience.
Ultimately, this game is one of the best ever, in my opinion, because it requires you to be smart and use your brain to progress through the levels. You must interact with multiple characters and all your interactions determine how the game plays out in the future. I have certainly gotten every penny worth out of this game and I would recommend it to virtually anyone who likes great video games.
