The S-Factor: Sonia & Silver is a ROM hack of Sonic the Hedgehog by Aquaslash & Pals. The game features Sonic's sister, Sonia the Hedgehog (from the DIC cartoon, Sonic Underground); Future psychic, Silver the Hedgehog (who first appeared in Sonic '06); as well as an evil version of Sonic named Scourge the Hedgehog (from the Archie Comics series) joining forces to take down a descendent of Dr. Eggman, named Eggman Nega (Who first appeared in Sonic Rush).

The hack features all-new levels as well as different movesets for each playable character (Except for Scourge who plays identically to Sonic). Sonia can accelerate into a whirlwind tornado or hit enemies with a spinning axe kick, While Silver can use his psychokinesis to throw objects at enemies.
