A brand new Sonic adventure begins in Sonic Hellfire Saga. A hack highly inspired by Castlevania and Ghosts n Goblins series. After many years of war against Sonic, Eggman felt in despair. No matter which plan or mechanism he creates ? he always lost battles. He began to believe that the reason of his failures was that God had turned away from him, so he prayed to the devil and wished Sonic?s death. Eggman could not imagine that his call would be heard. Sonic?s realm merged with Demons realm into a nightmarish realm with legions of hungry for blood demons. Help Sonic to escape from hell back to his home world!
