Single-Helmet Level

A Single-Helmet Level is one that has obstacles completely revolving around a particular transformation, which is the only helmet that can be found throughout the map. These levels are intended to be quite difficult.

List of Single-Helmet Levels
All helmets associated which each level are listed. In the case with Under the Ashes, there is no helmet, and the level revolves around the Kid transformation. While this is not the only level that does so (Echelon Rift 1, for example), it is the hardest one. Most of these levels are on the flag path, and all but one are in the latter two stages.
