Available Features and Zones

Play as Sonic and Tails

Miles “Tails” Prower joins his best friend Sonic the Hedgehog in Demo 2.0. Speed through the world together as a team, or play as either Sonic or Tails and fly solo through West Side Island.

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

The iconic industrial facility is the newest zone available to play in Sonic 2 HD. Find your way through the various pipes and ducts of the plant as you speed across a vibrant cityscape. You will need to be quick as platforms constantly shift and Badniks appear at every turn. Don’t get caught in the Mega Mack!

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

Built from the ground up for Sonic 2 HD, the SonicOrca engine recreates the feel of the original Sonic games and allows for modern features and functionality that were not possible in 1992. Utilizing modern graphics technologies, SonicOrca enables the high resolution visuals and overhauled interfaces seen throughout S2HD.

The engine is written in C# and uses SDL2/OpenGL for interaction with the operating system and graphics card. The engine also features built-in tools to allow for streamlined development.
