Secret Mission

From Sonic Retro

The necessary expansion to this page is a list of which level is unlocked by each key. I only know the SM25 is the last one and SM13 is one of Chun-nan. I count with the aid of anyone interested in helping with the research on this. --SonicUnleashedPS2 (talk) 12:41, 1 February 2024 (EST)

After some hard work, it is just missing the names of the mission levels and the item requirements for SM's 2, 6, 10 and 13, which are both topics still unreseached. --SonicUnleashedPS2 (talk) 21:40, 13 February 2024 (EST)

If you can, confirm if the list is right and complete the information about SM 6 and 13. --SonicUnleashedPS2 (talk) 12:54, 25 February 2024 (EST)
