Watch out for lava, enemies, spikes, and pits. In Act 1, Mephiles can be seen before dashing off.Įggmanland is thankfully much shorter, with Sonic only having the move though the daytime rooms. Returning from Sonic the Hedgehog (2006), Aquatic Base houses moving platforms, water tanks, and lots of enemies. A new area, a cave under the mansion, is added with traps to avoid and puzzles to solve. Sonic has to fight ghost to proceed though the mystic rooms and light lanterns to reach the goal guarded by ghosts. Ghosts sometimes chase Sonic though the stage. In Act 1, Classic Sonic must collect three Master Emerald shards before reaching the goal. Sonic must run across bridges connecting from giant pumpkin to pumpkin. There a beautiful sights, but just watch out for hazards. Windy Valley takes place inside of a tornado, a field, and a race track in the sky. In Act 1, Classic Sonic has to climb up the summit and defeat the mini-boss from the original game. Sonic can snowboard down the mountain and defeat enemies as he makes his way to the goal. Ice Cap is a steep mountain from Sonic the Hedgehog 3. However, an earthquake occurs in Act 2, causing Modern Sonic to fall into a cave. Much like in the first stage from Sonic the Hedgehog 2, Sonic must avoid bottomless pits, enemies, and spikes.
A new section above the undergrounds has been added. No lava appears, and secret passageways scatter the course. This stage has been made easier from Sonic the Hedgehog. Eggmans are in an after-credits scene and get in a humorous argument.
Meanwhile, the modern Sonic with Tails help eggman evil plan, and black hole sucks them into the same grey world.
Meanwhile, Classic Sonic runs though Station Square, older then when he was in Sonic Generations, and suddenly a black hole sucks everything into a land of grey. Some noises are heard as a red eye glows in the room.
