|Proceeded by||None, final zone|
The Crystal Egg Zone is the seventh and last zone in Sonic the Hedgehog 2 (8-Bit) and is where Tails is being held captive by Dr. Robotnik. However, Sonic can not get to the Crystal Egg Zone unless he has been able to collect all six of the Chaos Emeralds from the previous zones. Unlike Dr. Robotnik's previous bases of operations, the zone is not heavily industrialised, but is instead styled like a crystal palace. It is here that Dr. Robotnik, the final boss, is waiting.
