Machinery Sketches and Renders

Thanks to IceKnight, Jagboy, Solly, and Reala for finding these sketches from the Dreamcast Digital Presskit given away at the Nürnberges Spielwaren Messe in 1999

Here is a sketchy painting of the Egg Carrier in it's first form. It uses a lot more yellows than the final, making it look more sinister. Click the image a larger version.

Here are the walls inside the Egg Carrier. The painting makes it look more darker andmysterious, and seems to be much larger than the final, like a huge corridor rather than a main room. Click the image for the larger version.

Heres an image of the monorail surrounding the Egg Carrier. The Eggman face in the very back looks like it has a Viking hat on, and it coloured very differently. For the large version, click the image.
Heres a quick original sketch of the Egg Carrier done on some graph paper. Click the image for a larger version.
It looks like the Egg Carrier had a very different design at one point, almost looking like the Submarine from Disneys 'Atlantis'. Theres another sketch to look like an EggTrain as well. Click for the full image.
This is a painting of the cockpit of Eggman's Egg Carrier. It's very similar to the final design except for the dimples in the glass, which you can't see in the game. Click the image for the larger version.
Some more, cleaner sketches of the final Egg Carrier design. Click the image for the large version.
Some closer to final sketches with some colour. This also shows off the second mode as a sketch. Click the image for the large version.
Here are some renders of the Egg Carrier. It looks like some of these were used in the cutscenes of the final game where the Egg Carrier was in a scene with Eggman. Click the image for the large version.
Also included in this package was renders of Tails' two aircrafts. This is the Tornado 1 before it crashed. Click the image for the large version.
Here is the Tornado II in it's plane mode. Click the image for the large version.
And lastlyhere is a render of the Tornado II in it's second mode. Click the image for the large version.
