Sonic the Hedgehog 2, also known as Sonic the Hedgehog 2 Classic, is a remastered version of the original Sonic the Hedgehog 2 for the Sega Mega Drive. It was published by Sega for the iOS and Android in late 2013, having been developed by Christian Whitehead and Simon Thomley following their remastered digital re-releases of Sonic the Hedgehog CD and Sonic the Hedgehog.


Spoiler warning: Plot, ending details or any kind of information follow.

The title screen of the 2013 remaster of Sonic the Hedgehog 2.

West Side Island is a beautiful island full of green hills and fields. Despite its appearance, a legend speaks of seven mystical stones laying there. According to this legend, after an ancient civilization abused their power, these stones were sealed by the gods on the island.[1]

After the South Island incident, Sonic sets out for new adventures in his biplane, the Tornado. Eventually, he finds West Side Island, and decides to land there. There, he meets Miles "Tails" Prower, a two-tailed fox, who is inspired by Sonic's cool demeanor. One day, Tails marvels at the Tornado. However, it is in this moment that Dr. Eggman makes his entrance. Having learned of the legend, which he believes to be related to the Chaos Emeralds, he tears West Side Island up with his army of Badniks to find the Emeralds.[1]

Attempting to stop Eggman, Sonic and Tails explore the various Zones of West Side Island, defeating Eggman various times along the way. Eventually, the two use the Tornado to reach the doctor's Wing Fortress Zone. However, the Tornado is attacked, forcing Sonic, who managed to get aboard the vessel, to continue alone. After defeating Eggman once more, the doctor tries to escape to the Death Egg in space. With Tails returning in the Tornado, Sonic manages to grab onto Eggman's space rocket and ends up aboard the Death Egg. There, he defeats Mecha Sonic and the doctor himself in his Death Egg Robot. After defeating Eggman, a chain-reaction is triggered, causing the Death Egg to explode and forcing Sonic to escape. From there, the ending of the game will depend on the player's progress:

  • If the player has not managed to collect all seven Chaos Emeralds, Sonic will be saved by Tails on the Tornado. After the credits, a laughing Eggman will juggle the Emeralds the player did not collect while the text "TRY AGAIN" is shown.
  • If the player has managed to collect all seven Chaos Emeralds, Sonic (transformed into Super Sonic) will meet Tails, who has tried to save him with the Tornado. After the credits, the Death Egg will be shown crash-landing on Angel Island, and a frustrated Eggman will be jumping on the text "END" while he is being watched by Knuckles from a bush.
    • If the player is playing as Knuckles, the ending will be the same, except that Knuckles will not appear in the post-credits scene.


Tails in Chemical Plant Zone, the second Zone in Sonic the Hedgehog 2.

Trying to imitate the gameplay of the earliest Sonic games, Sonic the Hedgehog 2 is a 2D side-scrolling video game, which plays exactly like the original game. The player can take control of either Sonic, Tails, or Knuckles. They can also play as Sonic or Knuckles (the latter only through cheats) with an AI-controlled Tails following them. Each character has their own abilities that the player can use to their advantage. To move their character around, the player has to use Controlpadds.png, located at the left side of the screen. On the right, there is a button that will make the playable character jump when tapped.

Like the original game, Sonic the Hedgehog 2 is divided into eleven Zones which include the newly-added Hidden Palace Zone. Each Zone is divided into Acts, which the player must complete in less than ten minutes. In these Acts, many gimmicks, obstacles and Badniks can be found. Rings serve as the playable character's main method of protection; if the player is hit while having at least one Ring, they will survive, though they will lose all their Rings. On the other hand, getting hit without having any Rings will cause the player to lose a life. If this is the case, they will respawn at the last Star Post they touched, or at the start of the Act if no Star Posts have been touched. However, if the player runs out of lives, they will get a Game Over. To complete each Act, the player has to spin a Goal Plate or open a Capsule after defeating a boss. In either scenario, they will get bonus points based on the Rings they have gathered and the time taken to finish the Act.

New features

  • The main menu has been completely redesigned, as previously seen in the 2013 remaster of Sonic the Hedgehog.
  • The player can now save their progress in up to four save states. Infinite continues are provided as a result.
    • After completing the game, the save state will be named "COMPLETE". Tapping onto it will take the player to a Level Select-like menu, where they will be able to choose a Zone to play.
  • A Time Attack mode is added. In addition, it features a new exclusive Zone called Boss Attack Zone, which requires the player to defeat all of the game's bosses, except for the Hidden Palace Zone's boss.
  • The game features a new multiplayer mode.
  • The new boss of Hidden Palace Zone.

    Hidden Palace Zone, which was included as a scrapped zone during the development of Sonic the Hedgehog 2, is brought back. It comes with its own original boss and new enemies. It uses Mystic Cave Zone's two-player music as the background music.
  • The Level Select adds many new secrets:
    • Through a secret mini-menu, it is possible to use the elemental shields from Sonic the Hedgehog 3. There is also the option to replace all normal monitors with Random monitors.
    • This mini-menu also allows the player to play as Knuckles while being accompanied by Tails.
    • A secret eighth Special Stage is added.
    • The version of Hidden Palace Zone from the Simon Wai prototype has been added under the name Proto Palace Zone.
  • Through Debug Mode, the player can place a newly-added S monitor. This makes it possible for Tails to turn into Super Tails.

Time Attack

Main article: Time Attack

Time Attack is a new mode added to this game in which the player has to pass Acts in the least amount of time possible. The only playable character here is Sonic. All 1-Up Item Boxes are removed, but the time HUD also counts milliseconds. Boss Attack Zone has been added as an exclusive Zone for this mode, while Sky Chase Zone is removed.

When using Time Attack, the players select a Zone and Act to race through; the Acts available depend on how far the player has gotten in the game. Upon completing an Act, the player is graded based on their time. The game saves and records the player's best times, which can be compared to those on a personal list of best time logs.

2P Versus is a competition mode of the game. The player can play as either Sonic, Tails or Knuckles, and are given the election to join a match or create one. For the latter, they are given the following options:

    • Air Cap: Toggles the maximum running speed while in mid-air.

Playing sound "00" and selecting Special Stage takes the player to the Special Stage #1, playing sound "01" and selecting Special Stage takes the player to the Special Stage #2, and so on.

Sonic the Hedgehog 2 was released on 12 December 2013 for Android and iOS devices simultaneously worldwide. The iOS version also served as a free update to its earlier mobile port of the original Sonic the Hedgehog 2.[2]

On 21 November 2017, Sonic the Hedgehog 2 was added to the Sega Forever series of games for both mobile platforms to celebrate the 25th anniversary of the original game's release in Japan.[3][4]



  • This marks the first Sonic game to be released on Android devices.
  • Knuckles hiding in a bush during the new good ending is a reference to the North American box art of Sonic the Hedgehog 3.
