There are very few games that are in my opinion considered to be in the elite category. This game is one of them. This game redefined the FPS. The fact that cover plays such a major role changed the entire way I approached battles. Each level offered a new type of adversary and required a different strategy to win. My all time favorite game, Resident Evil 4 was the same way in that it redefined the genre. I am currently playing the game and cannot put the controller down. I do not want the game to end. I am certain that this game is the start of many sequels. This is the game to play this year.
