Sonic The Hedgehog "2006" PC Version was based off a heavily modified BlitzSonic Engine, but due to the limitations of the engine they decided to shift to another zone. Unity was chosen, and they started making the Kingdom Valley Zone as per the demo.
They also released a cutscene video which was recently deleted, but they have released a demo, which resembles the exactly ported version of Sonic 2006 Demo. The only difference was the graphics, which now has support of even 4K or maybe even 8K but it's a Unity engine, who knows?
- Exclusive graphics in stunning HD
- Full resolution support
- Works on Unity Engine
- Totally Realistic
- Fixes Bugs that were previously in Sonic 2006
