Sonic CD's Scrapped Rounds

Team Renewal

This mod returns the scrapped levels of the Sonic CD: Dubious Depths, Baneful Badland (reimagined Desert Dazzle) and Final Fever. Levels become part of the main game, not additional levels. They are made according to existing information and concepts about them, but at the same time, the mod does not try to authentically and accurately recreate the levels, but is a free interpretation of the author. All level's assets and objects are custom. The mod has a little customization of names and level music; some of the music was written specifically for the levels, while others were borrowed from other authors, most of whom are part of the team.
