Revision as of 13:51, 16 November 2019

Back to: Sonic the Hedgehog 2 (alpha).

Level select

Ss.s2bls.png

Enabled by default. Simply press A+Start on the title screen.

Edit mode

Notavailable.svg

Press C C Up Down Down Down Down Up then A+Start on the title screen, then highlight a Zone in the stage select and press and hold A.

2-Player VS mode

Sonic2Alpha MD 2P EHZ1 Start.png

Highlight a Zone in the stage select and press B+Start to play the level in 2-player split-screen mode. This does not work on levels with water in them (Hidden Palace Zone, Neo Green Hill Zone and the second Act of Chemical Plant Zone). Other than having a second screen to watch Tails, gameplay remains unchanged from 1-player mode.

Night mode

Notavailable.svg

Enable Edit Mode, highlight a Zone in the stage select and press C+Start.

Unused content

Art

Description
An early design for the moving blocks in Casino Night Zone, which is much smaller than in the final game.[1]

Objects

Placeable in edit mode

Description
Blank monitor, similar to the one in the original Sonic the Hedgehog. Does nothing.
The prototype Star Post seen in earlier versions of the game still exists. When deactivated, it is yellow, rapidly flashing white and red once Sonic has passed by.
The seesaw from Hill Top Zone (Scrap Brain Zone) can be placed in Emerald Hill Zone (Star Light Zone), complete with different colour scheme.
Flipping platforms for Chemical Plant Zone (Marble Zone). They don't have the correct art, but seem to work fine.
The Sonic 1 swinging platform still exists in Marble Zone, albeit with broken graphics.
Unknown enemy in Hidden Palace Zone (Spring Yard Zone).
Another one in Hidden Palace Zone. This one fires a projectile.
Stego with broken graphics in Hidden Palace Zone.
Gator with broken graphics in Hidden Palace Zone.
This seems to be the prototype Octus from Oil Ocean Zone, hovering, firing a projectile then moving off-screen to the left or right. Again, found in Hidden Palace Zone.

Unplaceable

Description
Though the Snail Badnik was replaced with Coconuts, its coding hasn't been dummied out yet. Interestingly, its object ID was changed from $54 to $59.
An early version of the Crawl Badnik, whose object ID is $5A. This Badnik has different behaviour from the final, where it will burrow out from underground, much like in early concept art by Tom Payne.[2] The mappings for this were made for the old art, but this prototype has newer art that doesn't match the mappings.[3] Interestingly, the part of the Badnik that is destroyed is the dirt it burrows out of, and not the Badnik itself.
