Crysis Warhead, the second Crysis game, this time developed by Crytek's Budapest studio and built on a new, enhanced and optimized version of Crytek's CryENGINE 2 technology, has shipped to retailers in North America and Europe, Electronic Arts and Crytek announced. In Crysis Warhead, players will don the Nanosuit of Sergeant Sykes, also known as 'Psycho', one of the most memorable characters from Crysis. More brash and aggressive than his Delta Force squadmate Nomad, players will experience Psycho's parallel story during the events of the original game, finding that life on the other side of the island is even more intense and explosive than they ever could have imagined. Aside from this new single player campaign, Crysis Warhead also features new multiplayer content.
