Status: Complete
System: Sega Mega Drive
Original game: Sonic the Hedgehog (16-bit)

Sonic & Johnny is a complete heavy modification of Sonic the Hedgehog by Lone Devil for the Sega Genesis. Featuring Johnny from Sonic Rush Adventure as a playable character that can be raced with Estimated Time Limits, New Zones with familiarity, Original Bosses, Sonic 1 Mode with slightly different layouts, and 2-Player Co-op that can be played without a second controller.


After Robotnik's dissatisfaction with Metal Sonic, Robotnik and his empire decided to own land, and reclaim all the Chaos Emeralds to mysteriously summon an individual from another dimension who calls himself Johnny. After being sold with Johnny's arrogant skills, Robotnik constructs a deal that would give Johnny the fame and recognition he always wanted by inviting him to his recently funded Atomic Stadium, an small island built for the strongest of racers with a special prize if one of the racers collects all Emeralds.

Sonic gets a report from Knuckles that his Emeralds is missing and later received a letter from Robotnik threatening Sonic to join his versus Grand Prix or else one of his friends will remain kidnapped forever. Sonic calls Tails to fly him to the nearest stadium to join the race to beat Robotnik's latest successor to Metal Sonic and find out what's really going on.
