Sonic the Hedgehog 2 (8-bit)/Development
From Sonic Retro
Sonic the Hedgehog 2 had gone through several changes over its development process. There are several rejected ideas, level designs, and other things that were left on the cutting room floor. The following details several of these things.
These screenshots are consistent with the content seen in the Sonic 2 AutoDemo, and were most likely captured from that release.
Under Ground Zone
Sky High Zone
Prototype screenshots show Sky High and Green Hills using some very basic checkered floors, similar to Sonic 1.
Aqua Lake Zone
Checkerboard floor and different palette for being underwater within the 2nd act. Found on the outside of a US Sonic 2 Game Gear bundle box.
Green Hills Zone
This image is thought to be a mockup, as far too many sprites are being rendered at once, for the hardware, the boss (and Robotnik) do not appear in this zone and there are a great deal more rings (in addition to the differing HUD, with the timer staying the same when compared to the possible mockup of Under Ground Zone, mentioned earlier).
