We have a patch for 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. Thanks: Blues/MyCrysis. This patch adds 64-bit executables for Windows XP x64 and Windows Vista 64-bit version. In Windows XP x64 a new shortcut will be placed under the Crysis Warhead program group. In Windows Vista right-click the Crysis Warhead icon in Game Explorer and choose to run the game in 64-bit mode. Games saved in 32-bit won't work properly when running the 64-bit version and vice-versa.
