It’s time to usher the past into the future in this enhanced recreation of Sonic CD!
Sonic travels to the distant shores of Never Lake for the once-a-year appearance of Little Planet - a mysterious world where past, present, and future collide through the power of the Time Stones that lie hidden within it. 
Sonic arrives only to find the once beautiful world imprisoned beneath a twisted metallic shell. His arch-nemesis, Dr. Eggman, has come for the Time Stones and with them, will soon have the power to control time itself!
In order to put an end to Dr. Eggman’s nefarious schemes, Sonic must use the power of Little Planet to travel through time; breaking Dr. Eggman’s hold over the future by destroying his machines in the past and recovering the missing Time Stones!
Featuring 16:9 widescreen, achievements, leaderboards and both the US and Japanese soundtracks, experience the adventure through time that introduced the world to Amy the Hedgehog and Eggman’s most evil creation, Metal Sonic.
