The S Factor: Sonia and Silver


Sonia and Silver, fan-made hack modifies the Genesis classic Sonic the Hedgehog to offer completely new levels and two new selectable characters to control (Sonia and Silver, if you haven’t guessed already). Each character brings with them their own suite of special moves and abilities, which puts a completely new twist on the Sonic formula.

Just Have Fun!
