Unlockable - Sonic 3 and Knuckles/Sonic and Knuckles Extra Stage + Alternate Endings | |
| Extra Stage: To play stage 14 in Sonic 3 and Knuckles, play through the game with Sonic and collect all of the chaos emeralds. When you get to the Death Egg Zone (stage 13), you'll have to fight Dr. Robotnik in what appears to be the last battle when he's in a giant robot. However, if you have all of the chaos emeralds, the fight will continue as Sonic changes into Super Sonic. The game mechanics are changed for this short stage, but it brings the final conclusion to the Sonic series. (This code also works for Sonic and Knuckles without Sonic 3, except the stage numbers will be different).Alternate Endings: Beat Sonic and Knuckles with Sonic, you'll get 1 ending, beat it with Knuckles, you'll get another. Play Sonic 3 and Knuckles and beat it with Tails, you'll get another. Beat the game using Sonic with all chaos emeralds, you'll get another ending; same when you beat the game with Knuckles with all chaos emeralds. Beat Sonic 3 and Knuckles with Sonic with all of the super endings, you'll get a slightly altered ending to the ending while beating the game with all the chaos emeralds; same with knuckles with all of the super emeralds. | |
