If your Crysis 2 Retaliation content download file from MyCrysis.com named dlcpack1.zip appears to be corrupt or will not open, this .zip file must then be moved into ‘C:\Users\<Username>\Saved Games\Crysis 2\DLC\’ in Windows 7/Vista or in Windows XP to: ‘C:\Documents and Settings\<Username>\My Documents\Crysis 2\DLC’.
To find this location in Windows 7:
- Go to Start > Computer > your Hard Drive (C:) > Users > <your username> > Saved Games > Crysis 2 > DLC.
- Open the DLC folder.
- Drag the dlcpack1.zip file that downloaded into the DLC folder, and close the window.
- After moving the file, launch the game and go to Server Browser.
The new maps should be present.
