This is the Serious Sam Gold Edition in two CD-ROM images (each in .BIN & .CUE) in one .ZIPX archive. This includes 'The First Encounter' & 'The Second Encounter'. Both ripped from original CD-ROMs. These are the US versions of the games, so the US update-patches are included, one for each game. Also included is the Serious Sam Gold Edition Manual (in .PDF).
No CD-keys needed, cracks are not a requirement, plays online without problem--all at 100%. Just mount, install, apply patches, play, and enjoy!
