This game is not a sequel to Crysis. This is a parallel to that Crysis adventure in which you play as Psycho sergeant already met in the first part of the saga (which should comprise three). The environment is still beautiful, the nano-suit is always the same. Some additional weapons: machine gun, anti-personnel mines, anti-tank mines, ... Overall the game is (slightly) more optimized than the first, it is fluid on my config: Core 2 Duo 3GHz, 8800 GTS 512 graphics card, 2 GB of RAM. I play in 1280x1024 (19 inch) high details. The gameplay has evolved against: the action is now more sustained, there is little downtime. The enemies come thick and fast, there is more ammunition available, many explosive and / or flammable objects are there to put a little atmosphere ... The scenes where the player is on a moving train, attacked vehicles and helicopters are really well done, without equal in the first Crysis. This rapid succession of enemies, vehicles, explosions, gives a little arcade side, very nice. There is less alien, I do not think anyone will complain. The price is reasonable, giving good value for money. Many criticize the system of protection, but it has the merit of allowing to play without the DVD in the drive.
