Sonic the Hedgehog 2 remastered for mobile devices, which was one of our favorite games of 2013, has apparently been hiding a few juicy secrets. Via developer Taxman in the Sonic Retro forums, early versions of the game had a few additional zones planned out. The first, dubbed Egg Gauntlet Zone, was a mode in which the player went through each boss one after another. Unfortunately, this feature was not included in the final game and not all the assets are available. However, crafty fans have been able to resurrect the mode via a bit of modding. Unfortunately, a recent software update has removed the assets needed to play the stage. Thankfully, the stage has been preserved for all to see in the video above.
The second secret stage, entitled Proto Palace Zone, has not been cut and can be accessed via some simple codes!
