Egg Carrier

Submitted by: Rlan

Big is wandering through the Egg Carrier innards, and next to the EGGMAN buttons, but if you look closely, they're green and much smaller in this image. In the final, they're orange and a lot larger.

Click the image for a larger version of it.

Knuckles is running through the same area as big, but the floor is much lighter in colour. In the final they're much more see through to see the machinery working inside it.

In the video Knuckles tries some of his punching moves, those which are actually in the final game! The lighting model is reacting horribly to Knuckles and is making him half black.

Here is Tails on the Egg Carrier with the Tornado 2, but it's still intact, and in its first mode! In the final the plane would have crashed and turned into the Tornado 2 at this point.

The same scene is played in the final version, but if you look closely, all of them are E-102 Gammas! Each one of them is red and has an arm, while in the final each E-100 series is different in colour and has an allsortment of arms.

Again, the same scene, but from a different angle.

Although not exactly a prototype screenshot, Gamma pushes down this button and it doesn't move. This was also in the original Japanese release of Sonic Adventure, but in the American, European, and 'Sonic Adventure International' versions of the game it is fixed so that it does push down.

Sonic is talking to Eggman in the cutscene before the Chaos 6 fight, but his mouth moves very differently to the final. He's got a huge bottom lip and seems to just jabber up and down.

This is Eggmans room of operations, but it's differently colours to the final game.
