Sonic Attack

From Sonic Retro

Sonic Attack is an Amiga music collection produced by Dual Crew Shining. It spans four disks, and Sonic is prominently featured in the collection's artwork. It includes a hidden part which is a flat and somewhat limited recreation of Green Hill Zone, with completely custom graphics. You reach the hidden part by booting the Amiga with disk 4 of the production, rather than disk 1 as you would normally do.
