Lost World

Submitted by: Scott Prower

This image was one of the first of Sonic Adventure to become avaliable, and sticks very closely to it in the final. In the final the textures are slightly different.

In the prototype video this marker is a little a fair distance away from the one in the final.

Taken out for no particular reason, this great 'balcony' across the side of the lost world lost the great floor texture in the final. In the final, it's been replaced by a very basic sand path.

At the beginning of the level, Sonic can easily drop down these steps, but in the prototype video Sonic has quite some difficulty in getting down, stopping and starting on each step.

Submitted by: Rlan

Just down a little further is a hazard area. Sonic must cross three rows of fire arrows, and another caterpiller enemy. Botht hese items are taken out of the final, with the Fire arrows only seen in the mirror area later on.

The snake room is still intact, but the giant snake seems to be floating in thin air! The water rising must not have been implemented yet.

This is the end of the Waterslide down, which goes down the waterfall. Here, Sonic is running down the waterway, but in the final he slides down it.

Knuckles is running around his section of the Lost world, but according to the level procedure, he should have received the shovel claw by now.

Submitted by: Scott Prower

Again, Knuckles is walking through an area without the Shovel Claws.

Submitted by: Rlan

In the prototype video and the Japanese advertisements Knuckles is seen running and jumping around the Chaos room, but in the final he can't enter it at all.

Submitted by: Rlan

Knuckles then proceeds to fly around the room. In the final game, this is where Sonic finishes Lost World.
