Sonic 2 Beta

Sonic the Hedgehog 2 for the Sega Mega Drive / Genesis is a fantastic game and I have fond memories of it.

Below is the complete collection of beta and prototype builds of the game (versions before the final version was released to the public) that have been found and descriptions for each one.

The controls are the same for each game:

Arrow keys = Move
Enter = Start/Pause
Z, X or C = Jump
Hold Down Arrow & a Jump Key to perform a Spin Dash

Full Screen mode – Choose the last option on the bottom left of the screen as you hover your move over it.
Click ‘Allow’

Sonic 2 Beta – Simon Wai prototype

Sonic 2 Beta – Beta 4

Sonic 2 Beta – Beta 5

Sonic 2 Beta – Beta 6

Sonic 2 Beta – Beta 7
