An Instant Classic!!
The single player mode of this game is short but sweet. You change between two guys who are fighting in the Middle East or in Russia. Somehow their mission is connected. The story will hook the player until they finish it, and the ending is a very good one. You can play trough five different difficulty modes. Besides doing the missions, you can also find the 30 Intels scattered through each map.
