Red Gate Ruins is a hard-difficulty track based in the City, and contains a wide variety of features, such as several split pathways, a very large number of Grind Rails, and obstacles nearly everywhere.
In Red Gate Ruins, 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.
Red Gate Ruins 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 by running up a small hill, and will quickly come across the first of many areas of the track that contains two lanes of short Grind Rails with spikes, Rings, and enemies placed directly on them. The racers then must navigate around a large number of obstacles, which holds true on Grind Rails and throughout most of the track. There are several splits in the track; one of which goes under the upper pathway on two Grind Rails, while the upper path continues and has several obstacles, but is more direct. Another is at the end of a backward-facing Conveyor Belt, and racers must quickly go to the left directly at the end of it from the main path if they wish to take it. The finish line can be found beyond sets of alternating ground and Grind Rails, and a series of hurdles and Item Boxes in the racers' paths.
