A new skin for the VTOL in Crysis Warhead and Crysis.
Go to your Crysis game folder -> Electronic Arts -> Crytek -> Crysis Warhead-> Game.
Copy the downloaded zz_***.pak file into the current game folder (Game).
If you use modified object files, scripts, textures the cheat protection won't let you play.
You must play on "High"-Texture Settings to see the alternate texture.
