Quick and dirty, I have modified the original Crysis no intro fix for the recently released Warhead which has 2 more intro screens that unlike the original game are not skippable as far as I know. Almost as annoying as forcing your paying customers that DRM crap. And while at that, I should mention the DRM is pretty decent in Warhead, not requiring you to put the DVD in the drive each time you want to play.
Click here to download the patch, unrar it into the games installation directory at: \Game\Localized\Video and then run remove.intro.crysis.warhead.bat
The only thing it does is renaming all files beginning with “Trailer” so you might as well just delete them all and be done with it ;)
