Quick notes

Six campaigns share one crisis. The same locations appear from different viewpoints as Eggman pursues Chaos.
Playable abilities change exploration. Tails can fly, Knuckles can climb and glide, and Amy relies on her hammer.
Tikal explains the ancient conflict. The past sequences link Chaos, the emeralds and the Echidna people.
Gamma and Big change the pace. Gamma’s timer rewards efficient targeting, while Big’s stages are fishing challenges.

Playable abilities change exploration

Relationships and campaign context
Subject	Connection	What to remember

Amy and ZERO	Pursued hero and robot	Distance and hammer timing matter
Big and Froggy	Friends separated by the crisis	Froggy is the stage’s essential catch

Useful tip

Gamma’s timer rewards efficient targeting, while Big’s stages are fishing challenges.
