Now that Sonic and Tails have defeated Eggman, they can continue on their adventure. But just as they were about to leave Eggman steals the Chaos Emerald in their possession gives it to Chaos, transforming him to Chaos 1. Tails then recommends to get all the Emeralds before Eggman so that Chaos won't become it's perfect form.
After the cutscene, go up to the steps to the front of the workshop to find a green object. That is the Wind Stone, pick it up and bring it to a cave near the waterfall with wind blowing. Put it in the key slot to open the next stage.
Get the Chaos Emerald![edit]
This stage has three parts to it. The first part is simply going forward through the first parts of the stage. You will come to a point where you see a windy path, take it and try to point your control stick forward so you don't run the risk of falling. After the windy path, a tornado appears and sucks you up. The second part is the inside of the tornado. There are many springs and jump pads you will have to take in order to get out of the tornado. The third part consists of long runs through some windy paths and stretches of those metal tracks all the way to the end. Get the Chaos emerald at the end to beat the stage.
Level B: Collect 50 Rings and break the capsule[edit]
Level A: Break the Capsule in less than 3:00:00 minutes[edit]
Upgrades Time[edit]
Leave the Mystic Ruins by getting on the train and heading back to Station Square.
Light-Speed Shoes[edit]
Head towards the back of Station Square, which now has the police block removed and look for an open manhole towards the left and drop inside it. Jump onto the second floor with the exit sign and you'll see the Light-Speed shoes glowing in front of Sonic. They allow Sonic to use the Light-Speed Dash move, which lets Sonic run at light-speed on a trail of rings. Grab the shoes, push the button, and use them for the first time to get out of the sewers. Once out of there, you'll end up at a shop and notice that it is dark outside, this means that the casino is now open! But before you get your gambling addiction going on grab the Crystal Ring.
Crystal Ring[edit]
Head back to Station Square Hotel and go up to the second floor. There are two buttons, one to make a path of rings appear and the other to open the doors on the other side. Charge up your Light-Speed Dash and press both buttons. Dash off to the other side using the rings and get the Crystal Ring. It makes the charge up time of 'Light-Speed Shoes' shorter by half. Push the button in the room to open the doors and leave.
