Very early gameplay of a Sonic fangame in the Unreal Engine, using the SGDK codebase made by Xaklse.
The level is called Ruined Relic.
The music is Castle Dracula from Castlevania: Harmony of Despair.
If you think you can help with the Sonic The Hedgehog: Incursion project, then send me a PM. Right now, people who can model and animate are required.
