Sonic 2 Advanced Edit


Sonic 2 Advanced Edit features 7 entirely new zones, each full of unique enemies and with a boss whose gameplay varies depending on which character you play as. Playable characters are Sonic, Tails, Knuckles and Amy. Furthermore, as bonus content, the hack features the 5 zones from the 2008 release, brushed up to be fully playable. Upon completing the 7 main zones, you obtain a code to access the level select from which you can play the bonus zones by selecting “South Island 1”.

There are 69 big rings scattered throughout the 7 main zones. Collect 7 of them to gain the ability to turn super once you have at least 50 rings in any given level.


  • Sonic, Tails, Knuckles: As in S3K. (No spindash for Tails.)
  • Amy: A, Down+A: Hammer attacks; B/C, Down+B/C: Jump/Spindash.
  • Super forms: To enable, hold A+B+C while jumping. (No super form for Tails.)
  • Level reset: While paused, hold A+B+C to go to start of the level/last starpost (costs 1 life).

Distribution of the 69 big rings:

  1. Neo South Island: 9
  2. Cosmic City: 16
  3. Bamboo Jungle: 10
  4. Blue Mountain: 11
  5. Robotic Ruin: 9
  6. Dusty Desert: 13
  7. Eggquarium: 1

This is almost certainly the final release of this hack. It has been about 10 years in the making, with very little progress in the last few years due to real-life commitments and rika_chou and qiuu as the only remaining contributors. Many aspects are not exactly as we envisioned due to limited time, but we are quite happy with the result nevertheless.

As always, good luck and Have Fun!
