Sonic the Hedgehog 2006: Last Story Part 1/2: End of the World

After completing all three main episodes featuring Sonic, Shadow, and Silver, players discover an additional finale that brings the characters together. In Sonic’s episode, he defeats Dr. Eggman and rescues Princess Elise. Shadow, aided by Rouge and Omega, battles Mephiles and his clone army. Silver, with Blaze’s help, seals Iblis and sacrifices herself to protect the future. However, Mephiles survives, escapes with a Purple Chaos Emerald, and orchestrates a plan to kill Sonic, causing Elise to cry and unleash Iblis. The resulting fusion creates Solaris, who warps time and space into chaos. To defeat Solaris, the team must gather the seven Chaos Emeralds across seven levels—each controlled by a different character—while navigating distorted environments and dangerous rifts. By collecting all emeralds, they aim to restore Sonic’s life and confront the final threat.
