STORY

Months have passed since Eggman's last major attack, and his silence has become unsettling. Tails eventually notices something strange through his telescope: Badniks are being launched into space while enormous beams of energy fire from Little Planet toward the Sun.

Sonic heads to Little Planet to investigate and quickly discovers the scale of Eggman's plan. A massive Dyson sphere is being assembled around the Sun, powered by machinery spread across the planet. Once fully activated, the structure will drain solar energy and cast the Solar System into a permanent eclipse.

There is no time to waste. Sonic begins moving between the Present and the Past, destroying vulnerable parts of Eggman's network before they can be reinforced. Every successful strike gives him more time to reach the source of the operation and shut the Dyson sphere down for good.
