Guest difficulty

For regulations surrounding guest difficulties, see: Ranking Criteria

A guest difficulty (or GD for short) is a difficulty of a beatmap that is not created by the beatmap host. They can usually be identified by their difficulty name containing the guest creator's username. A beatmap featuring multiple creators is also known as a collaborative difficulty.

Many guest difficulties are often requested by private messages between creators. Although GDs can also be requested in modding queues.
