Required if you played Crysis
This game is the extension of the original Crysis and follows the story from the viewpoint of Psycho. The game plays like the original with a few enhancements to the engine. The vehicles are a bit better and the graphics are a bit sharper. Story is much more focused and sometimes makes a few leaps. Game is also shorter than the original but contains very good cinamatics. One of the best I ever saw. Definitely a winner and a must if you played the original Crysis.
