Sonic vs all Mecha Sonics | Sonic 3D in 2D

After clear the game once, you can find a secret switch which will activate all Mecha Sonics.
If you like sonic, I hope you enjoy this video.
Fighting against those robots is much much harder than I thought.

Sonic 3D in 2D is just a fan game.

3D in 2D is a fan remake(?) OF sonic 3D blast that makes it what it could have been if it was like the other sonic games on the megadrive
