Zone-Specific Sprites

Artwork Zone Description
Snailbot.png Emerald Hill Zone The snail badnik from the Nick Arcade prototype has the same movement pattern as it does in the prototype.
Bee sprite.png Emerald Hill Zone An alternate version of the Buzzer badnik. It behaves as it was planned out to in concept art. Its shots burn bridges, which will harm the player unless they have a fire shield.
Spr 3eyefish.png Chemical Plant Zone Another beta badnik, it now works fully. It moves around slowly but speeds up if it comes in close proximity with the player. It drops Bubblers as it's attack.
Sonic2iOS-Bubbler.gif Chemical Plant Zone Dropped by Mother Bubble badnik and explodes after touching the ground.
Sonic2iOS-CPZMetalPoles.png Chemical Plant Zone Unknown object.
Sonic2iOS-Fireball.gif Chemical Plant Zone A stationary fireball that harms the player, unless they are wearing a Fire Shield.
Sonic2iOS-CPZBall.gif Chemical Plant Zone A ball that will float in the air, and give chase if the player is in close proximity. When above the player's head, it'll explode and drop chemicals. The Bubble Shield can protect against this attack.
Spr cpzboss.gif Chemical Plant Zone Still unused.
Aquatic ruin door.png
Aquatic Ruin Zone Closes as soon as the player passes through it.
Sonic2iOS-GreenGrounder.png Aquatic Ruin Zone Same as Grounder, but green. A homage to Adventures of Sonic the Hedgehog.
Sonic2iOS-ARZPillar.png Aquatic Ruin Zone Pillar found in ARZ's sprite sheets.
Sonic2-mrzobject.png Mystic Cave Zone Weird platform made of rings, placeable using debug mode. It moves back and forth depending on which side you stand on.
Sonic2iOS-OOZBall.gif Oil Ocean Zone Checkered ball that behaves like the checkered ball in the Sonic 1 2013 game, rather than how it did in the 16-bit version.
Balkiry2.png
Sky Chase Zone A standing frame for the Balkiry.
S2-Turtle.gif
Sky Chase Zone Walking animation for the turtle.
Sonic2-giantlaser.gif

Miscellaneous Sprites

Artwork Description
Sonic1iOS-TailsContinue.gif Continue screen animation from Sonic 1 (2013 game).
SonicCD11-tailslifeicons.png These are leftover Tails life icons from the 2011 Sonic CD and Sonic 1 port.
CDTimer Leftover.png Leftover timer marks from Sonic CD (2011). Also the HUD sprites.
SonicCD11 Placeholder.png Likely related to Retro SDK's level editor which is used to create the game. The same icon was found in the Sonic CD and Sonic 1 port.

Game Config Menu

Sonic2ios-gameconfig.png

A game configuration menu is accessable by playing sound 00 three times in the sound menu. It has the following options:

  • Player: Choose any of the available characters/character teams.
  • Items: Chosse between all Sonic 2, Sonic 3 monitors, including the hidden ones.
  • Flight: Toggle Tails ability to fly.
  • Air Cap: Toggle the air speed cap.

8th Special Stage

Sonic2iOS-8thSpecialStage.png

A 8th special stage is available in the sound test level selection menu. By selecting sounds 00 through 07 the special stage you enter when choosing the special stage will change. 00 is the first level and every number after that is the next highest level with 07 leading to the new 8th level. This level features a purple floor, corkscrew loop, and a light blue Chaos Emerald.

Proto Hidden Palace Zone

Sonic2iOS-ProtoPalaceZone.png

As of Version 3.0.9 the Proto Hidden Palace Zone is accessable in the hidden stage select menu. Simply choose "Hidden Palace" in the menu. There are a few small differences from the Mega Drive incarnation. The water slide works and is fully implemented. It is also impossible to get too far in the level as the large emerald acts as a stage clear warp instead of breaking to let players through the bottom.

Egg Gauntlet Zone

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.[2] A map of the level can be seen here. A youtube video can be found here.

As of Version 3.0.9 the Zone was completely removed from the game.
