Lost Valley Zone

Lost Valley is a zone in Sonic Projector.

Lost Valley is based on the Sonic Forces stage of the same name.

Lost Valley is where players can find the Phantom Ruby.

Originally intended as an easter egg when Sonic Projector launched in early 2019, Lost Valley has gradually become more well-known and has since no longer been considered an easter egg.

The November 2, 2019 update is when Lost Valley was indoctrinated as a normal zone due to the introduction of Pumpkin Hill right next to it.

Further updates have made Lost Valley more obvious and easier to get to.

Lost Valley directly connects to Pumpkin Hill and Sandopolis.
