Unlike most commercial games currently available, Land of the Dead: Road to Fiddler's Green installs fully on the PC and is playable without a CD-ROM in the drive. The manual even suggests (as a troubleshooting measure) copying the two CD-ROMs to a folder on the desktop and installing from the setup.exe file there, bypassing the disks.
Land of the Dead was originally developed as a singleplayer PC game called Day of the Zombie, which had a four month development cycle and was ready for October 2004 release. Day of the Zombie was shown to Universal Studios around the time the movie Land of the Dead was being filmed in Toronto, Canada (where Groove is headquartered) - this is how the license was secured. The game was ported to Xbox, multiplayer functionality was added and environments were added to tie the game to the movie.
