  1. Worst ending (variant 1)

  2. Worst ending (variant 2)

  3. Worst ending (variant 3)

  4. Secret ending

  5. Knuckles solo ending

  6. Eggman solo ending

  7. Metal solo ending

  8. Sonic solo ending

  9. Knuckles and eggman duo ending

  10. Sonic and eggman duo ending

  11. Sonic and knuckles duo ending

  12. Sonic and metal duo ending

  13. Sonic, knuckles and metal trio ending

  14. Knuckles and metal duo ending

  15. Best ending

One faithful day Miles Tails Prower was just testing out his new energy scanner.Little did he know he fell right into a carefully planned plan....

First sonic.exe fangame so it might be a bit bad at times.

This game is inspired by knuckles.exe emerald curse and sonic.exe spirits of hell
