Desert Falls is a track that appeared in Sonic Forces: Speed Battle. It was unlocked in Tier 4, or upon reaching 1000 Trophies. It was later removed in favor of the other tracks in the game.
Desert Falls is an hard-difficulty track based in Green Hill. It contains long sections of track which are separated from each other.
In Desert Falls, the playable characters are stuck running down the level's road and can only move left and right between the road's four lanes (akin to the Quick Step). While running, the player can pick up powerups from Item Boxes and utilize the gimmicks native to this track.
Desert Falls has many environmental obstacles which the player can either jump over, roll under or move around. Running into one of these obstacles will result in the player taking damage and lose some of their Rings. Falling into bottomless pits on the other hand forces the player to restart from an earlier point on the track.
The racers begin on a small hill with Item Boxes set out in front of them. Outside of the regular obstacles that must be dodged, the track splits multiple times into very long sections that have up to four lanes each. The paths on the right always have more Dash Panels, Conveyor Belts and Grind Rails, while the sections on the left have more Item Boxes. The track eventually rejoins for the final time near the end before taking the players to many obstacles and Dash Pads, over a final set of Grind Rails, then reaching the finish line.
