Sonic J

Project Overview


Sonic J is a Sonic The Hedgehog based Work-In-Progress fan made game made by jean_tha_n00b (me), and has purpose of being an unofficial sequel to the classic game, Sonic & Knuckles.

The game contains two main characters:
Sonic the Hedgehog,

and Miles "Tails" Prower.

Sonic the Hedgehog is owned by SEGA. I do not own the franchise as I am not affiliated with SEGA and Sonic Team. This is a non-profit fan game and it should not be sold. No copyright infringement is intended by any means.
Zone List (Available for now):

  • Jex Island Act 1
  • Tutorial
As you can see this demo is very small as it features only two levels and characters. But as updates still go, new content will arrive very soon.
