Sonic the Hedgehog, commonly referred to as Sonic '06, is a 2006 platform game developed by Sonic Team and published by Sega. It was intended as a reboot of the Sonic franchise for seventh-generation video game consoles. Players control Sonic, Shadow, and the new character Silver as they seek to defeat Solaris, an ancient evil pursued by Doctor Eggman. Each character has his own campaign and abilities, and must complete levels, explore hub worlds and fight bosses to advance the story. In multiplayer modes, players can work cooperatively to collect Chaos Emeralds or race to the end of a level.
