HOW TO PLAY This game is an auto-runner meaning that Sonic (or whoever you play as) runs automatically. However it's possible to control their speed to make them faster or slower with the A and D keys. W is for jumping.
Omega disappeared! The Chaotix went to investigate but also went missing! Sonic and Tails are searching for clues in Green Hill when they find Metal Sonic. Metal escapes but not before Tails puts a tracking device on him! Why is Metal going to the Lost Hex?
