Diehard Challenge

"Don't get defeated!"

- The mission's description.

Diehard Challenges are certain type of missions in Sonic and the Secret Rings. There are a total of 7 Diehard Challenges, each mission for a separate stage.

How they work
Diehard Challenges are altered counterparts of the original level missions. The task is to complete the level (slightly shortened) without getting hurt once, since the player has no Rings to survive a shot.
