Lost Sprites
| Artwork | Name | Description |
|---|---|---|
 |
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 badnik 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. | |
 |
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. |
 |
Static TV Monitor | Powerup monitor which harms you when broken. Never seen in-game. |
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 Level slot |
|---|---|
| Emerald Hill Zone | Emerald Hill Zone (00 level slot) |
| Chemical Plant Zone | Metropolis Zone (04/05 level slot) |
| Aquatic Ruin Zone | Wing Fortress Zone (06 level slot) |
| Casino Night Zone | Hill Top Zone (07 level slot) |
| Hill Top Zone | Oil Ocean Zone (0A level slot) |
| Mystic Cave Zone | Mystic Cave Zone (0B level slot) |
| Oil Ocean Zone | Casino Night Zone (0C level slot) |
| Metropolis Zone | Chemical Plant Zone (0D level slot) |
| Sky Chase Zone | Death Egg Zone (0E level slot) |
| Wing Fortress Zone | Aquatic Ruin Zone (0F level slot) |
| Death Egg Zone | Sky Chase Zone (10 level slot) |
Level slots 01,02,03,05,09 all lead to Emerald Hill Zone and 08 is actually Hidden Palace. In the Sonic the Hedgehog 2 (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 a 18 zone game.
Time Travel
The concept of Time Travel in Sonic 2 was referred to in early concept art, as well as a July 1992 EGM article. Only past and present timezones are referred to in the concept art, so it may not have had as many alternate time zones as Sonic the Hedgehog CD. It isn't known at what point the time travel concept was dropped, but the 1992 EGM article refers to the game as being 40% complete whilst mentioning time travel concepts associated with the game. The concept art refers to the scrapped level Rock Zone as being the past version of the scrapped Desert Zone.Template:Sonic2Levels
