Available Features and Zones

Play as Sonic and Tails
Emerald Hill Zone
This tropical paradise off the coast of West Side Island finds new life in the hand-drawn graphics and animations of Sonic 2 HD. Run across the grassy hills and underneath scenic waterfalls as you save all the animals trapped inside Badniks across the beachside landscape.


Chemical Plant Zone
Hill Top Zone
This rocky region is full of hiking paths to explore, whether you’re scaling mountaintops by see-saw or plummeting deep into the dark caverns. Use vine ropeways to travel to unreachable places and take in the crisp cool air. Though be warned: The terrain is volatile, and there’s no telling when earthquakes will strike next.

About the Engine
