SRB2 Demo 2 Beta Quest / 1998-2001 Development Maps Walkthrough - Sonic Robo Blast 2 (Demo 2)

Taking a trip through 1998-2001 dev maps, these were given to the winners of a contest in 2001, most of them are from the very early days of SRB2's development.

Most of these levels are very different from their modern counterparts, some levels were either completely scrapped or have had their concepts merged with each other and turned into other zone or moved to other levels. Only a few parts of the level designs here made it to the current version of the game.
