This is the hack you get if you combine Sonic 2 with Sonic Heroes. Very much like Sonic Heroes, the player has the ability to control up to three characters, with one being the team leader whilst the other two tag along, and characters can be rotated at any time. Only Team Sonic (made up of Sonic, Tails and Knuckles) is playable, though Amy Rose makes a non-playing appearance near the end of the game. The story, levels and music are all the same as in Sonic 2, though the collectibles are from Sonic 3 and Knuckles, giving the characters more useful items such as the giant bubble. Like Sonic 2, 7 chaos emeralds from special stages must be collected in order for super transformation to be possible, and when 50 rings are collected, all three transform into their super form (very much like the final boss of Sonic Heroes, except the trio can transform immediately after 7 emeralds are collected). A player can also play as a team of two characters, or as an individual, though a three character team is recommended. Sonic 2 Heroes, overall, is as challenging as Sonic 2, but with 3 characters and different collectibles, it might be slightly easier to navigate through the many levels this game has.
