Agree with gamespot on everything except the weak story comment.
Story: This sequel to RFOM starts right where the first one ends. Nathan Hale, an American Liutenent, is once agains the star of the game. The prologue shows Hale's chopper crashing down into an American army base in Iceland. After Hale escapes, he is taken to the mainland. In two years time, the Chimera attack the U.S. from both coasts, pushing the population into the center of the country. Throughout the course of the game, you guide Nathan Hale through various locations in the U.S. such as Twin Falls, Idaho and Chicago, Ilonois. Hale becomes more and more infected as the game goes on. I won't give the ending away.
Pros: Intelligent enemy A.I., fun to shoot weapons, unique enemies, giangantic bosses, Interesting story.
Cons: Minor techinical glicthes, difficulty level may piss off some people, Occasional wonder on what to do.
Bottom Line: A-
