Sonic Fans Did The Impossible...
The Sonic Fanbase has come together to recompile and unofficially port Sonic Unleashed to PC and Linux. This is a day I never thought would happen since, when a game is lost in port-limbo (Like Blood Borne) they never seem to make it to the other side. But I guess after watching Sonic 3, the fans found Super sonic like determination to do it themselves and port Sonic Unleashed to PC and Linux themselves...
