This data disk is also known as Code Mack.
Classicamiga discovered that two data disks exist for Syndicate, called American Revolt and Code Mack. However after testing both data disks we concluded that they are identical. We know that American Revolt was released via magazine cover disks in the UK, however we cannot find any information about Code Mack other than its physical existence as an ADF file in the TOSEC archive. Therefore we are assuming Code Mack was the development name for Amercian Revolt.
American Revolt contains an additional 25 missions for Syndicate. They difficulty level is harder than the missions in the original game so make sure you have played though the original game a couple of times before trying them. In order to play these new missions this data disk replaces the original disk 4 from Syndicate. To reach these new missions you need to complete all of the normal Syndicate missions for Europe and Asia and then you will begin the 25 new missions.
This Data Disk was distrubuted exclusively by Future Publishing on behalf of Bullfrog through the Amiga magazine Amiga Format. Readers could order the disk directly for £12.99 via page 70 of issue 60 (June 1994) of Amiga Format. Purchase of this data disk might also have been available in issue 38 (June 1994) of Amiga Power, which was also owned and published by Future Publishing.
