Sonic CD: Episode 2 (AKA Sonic CD 2, Sonic CD II, or even Sonic CD: Episode II) is the sequel of the SEGA CD game Sonic CD. This sequel presents Classic Sonic, not modern. This also presents the three Sonic robots (Metal Sonic, Mecha Sonic, and Silver Sonic. This is downloadable on the XBox 360 for 180 points and a packaged version. There is also a Sonic CD 2 application for iPod Touch, iPhone, and all other handheld cell phone devices. The demo is only the first act of the first world and you can only play as Sonic. Even though it's a sequel to Sonic CD, It takes place right after all episodes of Sonic the Hedgehog 4.
After the events of Sonic the Hedgehog 4, Tails invented his creation to protect the Master Emerald for Knuckles to come for his and Sonic's vacation, along with Amy. When they celebrated at Palm Tree Panic, Robotnik appeared. Suddenly, the fat scientist knocked Sonic and his friends out, while Metal Sonic and his two friends captured Amy! After an hour, Sonic woke up. He found himself at the Death Egg. But how? Then he realized that he was in the Death Egg that he blew up at the time he met Tails. Even though it was ruined, Sonic went off to defeat Robotnik and save Amy and find Tails and Knuckles.
Mighty isn't part of the story. He is an unlockable character.
Same as Sonic.
Beat the game two more times with Knuckles with either ending.
The application of Sonic CD 2 is the same as the XBox version except the whole game uses sprites instead of 3D Models in 2D and 2.5D.
All the characters (except Sonic, which is a playable character by default) are unlockable except for Mighty. The reason is that SEGA couldn't find a cheat to let Mighty be a playable character, so he was scrapped from this version. Sonic, Tails, and Knuckles all have their abilities from Sonic 3 while Amy has her abilities from Amy Rose in Sonic 2.
