Egg Gauntlet Zone data remains in the final game but can only be accessed through hacking. It was the first attempt at a Boss Attack level that had some original artwork such as mechanical palm trees and flashing lights. It was to be a full Zone that acted as a testing facility for some of the bosses inventions rather than just have a level with bosses back to back. The act was nearly completed and needed just a few graphical changes to replace missing, unpolished, and placeholder graphics. Sonic Team did not approve of changing the location, colors, or graphical style so the level was scrapped and the Boss Attack level that was used in the final game was created.[]

Lost Sprites

Artwork Name Description
Aquatic ruin door.png
ARZ Barrier Unused door barriers from Aquatic Ruin Zone.
Unused Balkiry Frame Unused frame of the Balkiry badnik with landing gear.
Walking Turtle Walking sprites of the turtles that pop out of the badniks in Sky Chase Zone. Normally you'll never see this, since the animal never has the opportunity to hit the ground.
HPZ Icon Level Select icon for Hidden Palace Zone, which never made it into the final game. The art however, is present in Sonic 3's level select.
WFZ Laser Large laser shooting through a spinning platform in Wing Fortress Zone. Never seen in-game.
MCZ Ring Platform Weird platform made of rings, placeable using debug mode. It moves back and forth depending on which side you stand on.
WFZ Spinning Pole Weird spinning pole that acts like a badnik - you can destroy it, and it can hurt you, but it doesn't actually move.
S2 static monitor.png
Static or blank TV Monitor Powerup monitor which harms you when broken. Never seen in-game.

Unused Music Track

In the sound test, song $10 is actually a unused song. This has been established to be the music meant for Hidden Palace Zone.

True Level Order

The level order that is used during gameplay is actually quite different from the intended order according to the level slots. A simple level select Pro Action Replay code (FFFE10:??00) can be used to verify this:

Order in gameplay Actual
Emerald Hill Zone Emerald Hill Zone (00)
Chemical Plant Zone Metropolis Zone (04/05)
Aquatic Ruin Zone Wing Fortress Zone (06)
Casino Night Zone Hill Top Zone (07)
Hill Top Zone Oil Ocean Zone (0A)
Mystic Cave Zone Mystic Cave Zone (0B)
Oil Ocean Zone Casino Night Zone (0C)
Metropolis Zone Chemical Plant Zone (0D)
Sky Chase Zone Death Egg Zone (0E)
Wing Fortress Zone Aquatic Ruin Zone (0F)
Death Egg Zone Sky Chase Zone (10)

Level slots 01,02,03,05,09 all lead to Emerald Hill Zone and 08 is actually Hidden Palace. In the Simon Wai prototype some of these were used for scrapped levels. 02 was used for Wood Zone and 0E was used for Genocide City Zone.

Commentary found in the Sonic Jam strategy guide reveals that the level order could have been even more different. It states that Chemical Plant Zone was meant to be the 10th zone back when the game was planned as an 18 zone game.
