Martin Konrad has found more beta stuff in his collection of old gaming magazines: in these scans we can see more screens from an early version of Sonic Triple Trouble/Chaos 2 for the GameGear. Martin says that “There is some kind of 3D bonus levels which is not used in the final game and a couple of scenes with Nack/Fang which were removed.”
“Another scan shows a level in the first world, but the level layout is different from the final version”. You can check all these beta-screens and more in our Sonic Triple Trouble / Chaos 2 beta archive. Thanks a lot to Martin Konrad for the contribution!
