How do you make Command and Conquer Generals become Command and Conquer General Zero Hour?
Command and Conquer: Generals Zero Hour is an expansion to
Command and Conquer Generals. Install Command and Conquer: Generals
then install the expansion pack to play the expansion.
In the menu where you select the game you want to play, the
button that says "Command and Conquer Generals" should have a
button directly below it that says something like "Command and
Conquer Generals Zero Hour"
PS. this is for command and conquer: the first decade. Other
wise you will need to download the separate game or buy a separate
disk.
