The Sonic Generations demo released June 23rd on Sonic’s 20th Birthday was hacked on that very day by various community members, including those at Sonic Retro. Found within the unusually very large file was the game’s entire level list, boss list, mission list, characters, badniks, items, some music files (though nothing past Green Hill Zone) and the presence of the Chaos Emeralds and super forms for both Sonic’s.

The items revealed include the return of elemental shields from Sonic 3 and Sonic & Knuckles. The lightning shield, fire shield and bubble shield item boxes were both found in the demo assets, along with images of how they look in-game. The Spike Wisp and Rocket Wisp powers from Sonic Colours also make a comeback. As for the Chaos Emeralds, they too appear to be an item, which suggests Classic and Modern Sonic’s Super forms will be playable in the game’s various stages.

Update: Images removed at SEGA’s request.
