Wow...
I must say, this is one addicting game. What really gets you into this game is how the music, the sounds, and the action blended and makes you feel a part of the action. I must compliment you on those killer music choices. The final level was breathtaking. As for the action, it really kicked in and kicked in well. It couldn't have done better (again, the final level was awesome). What I thought was pretty cool was how interactive the environment was (something these "shoot-em-up" style games need). I have to say I thought it weird for a machine gun to come out of Bush's desk but whatever :P
Great game! I only wish it was longer!
