At the end of a long adventure, Sonic travels to the distant shores of Never Lake for the once-a-year appearance of Little Planet - a mysterious world where it is said that past, present, and future collide through the power of the Time Stones that lie hidden within it.
Sonic arrives with a star struck Amy Rose in tow only to find the once beautiful world chained and imprisoned beneath a twisted metallic shell. Sonic's nemesis, Dr. Eggman (a.k.a Dr. Robotnik), has come for the Time Stones and with them, will soon have the power to control time itself!
The fate of the world is determined by the choices you make throughout your adventure! Fight through the past, recover the Time Stones, and defeat the evil Metal Sonic in order to save the future from Dr. Eggman's nefarious schemes!
