Sonic 2: Aluminium Edition is a hack of Sonic the Hedgehog 2 for the Sega Mega Drive/Genesis by Dr. Eggfan. It doesn't feature any ASM content nor new layouts, it's pretty much Sonic 2 with a few new visuals, and for some reason completely different names for the same zones. There's also a partially restored Hidden Palace Zone in there.
