Levels (SADV1)

From Sonic - Wiki on Neoseeker

Please note that "Egg Rocket" and "Cosmic Angel" are technically in the same Stage Group, although despite being the only Stage which takes place inside the Cosmic Angel itself, it is considered to be "Act 2", as it follows on almost directly from the "Egg Rocket" Stage.

Also note that the "X-Zone" is part of the exterior of the "Cosmic Angel". So, technically, "Cosmic Angel" should be "Cosmic Angel Act 1" and "X-Zone" should be "Cosmic Angel Act 2", although we decided to follow the game's Stage Selection Menu here.

This should clear up any confusion as to where we got "6A" and "6B" from.

The actual Stage order is as follows here.

• Neo Green Hill 1
• Neo Green Hill 2
• Hidden Base 1
• Hidden Base 2
• Casino Paradise 1
• Casino Paradise 2
• Ice Mountain 1
• Ice Mountain 2
• Angel Island 1
• Angel Island 2
• Egg Rocket
• Cosmic Angel
• X Zone
• Moon (Only as Sonic with seven Chaos Emeralds)
