Sonic Nebulous is a fan-game based on the Sonic the Hedgehog SatAM TV series and includes elements from the original Sonic the Hedgehog games and comics. I have released a few previous versions demonstrating its progress and capabilities. Throughout its development, I will continue to post updates. Sonic Nebulous v3.
I've designed this mode as to where one player can switch between two characters. The other player that is not being played becomes controlled by the computer AI until you switch back.
