Ditto. But anyway, starting from the end of the preview:
Sonic jumped up onto a wall, and went back down to his platform, flipping it into the air, with the lava covered side up.Sonic held on to the edge and flipped so the lava was down and landed on an LB, destroying, but partly filling the room with lava. Sonic then jumped onto another wall and cometed towards another, bounced off it onto a wall and jumped back to the platform. The remaining shot a lava whip at Sonic, who jumped and made them all pull together into a ball of lava. Sonic cometed at this one and it started filling the room with lava. Sonic then notiiced his only way out was about to be closed with lava! Sonic bolted towards it and made it through just in time. A door cloased behind him and Sonic heard a whirring noise.Sonic turned around and saw a drill machine coming right at him! Sonic broke through the wall and came out right next to Tails and Knuckles. "RUN!!!!!!!!!!!" Sonic yelled. And as he said that, the machine came out of the volcano! Sonic jumped and fell back to try and hit him, but Eggman used his drills as shields and blew Sonic back to where he was before he jumped. He caught up with Tails and Knuckles and told them, "Stay to my sides.I'm going to try throwing earth at him." Sonic shot his leg down faster than usual, and shot chunks of earth towards Eggman. While his drills were busy with the chunks of ground, Sonic jumped towards the cockpit and hit Eggman. His drills were still trying to stop the Earth, so Sonic jumped at him again, but this time, Eggman opened the main section of the machine, revealing the master emerald, and a laser. The laser bolted at Sonic faster than Hyper Sonic, but Sonic turned into Super Sonic and created a shockwave, destroying the laser and attacking(but not destroying) Eggman. Eggman's engine had been destroyed, and Sonic transformed back out of the power being drained. Eggman blasted his drills as missles at Sonic (And Tails and Knuckles, who had stayed to watch.) , but Sonic transformed back and created a shield as powerful as the shockwave...
