This project is a brand new take of redesigning of Sonic 3! This project consists of a 3-in-1 package made by Jdpense, that has new routes and scripted events for each of the players in the game! In addition an overhaul of changes to the levels there are also changes to Special Stages with an overhaul of layout changes along with newer spheres from the last build added for an extra challenge.

Although, this build is different from last year's, since it's switched over to Sonic 3 Alone as the base game instead of Sonic 3 and Knuckles due to it being more simple to use. Along with that, Sonic and Tails are the only playable characters in this build as there wasn't enough time to flesh out the other characters.
