McOsu

McOsu is a circle-clicking rhythm game client for osu!(standard) beatmaps, designed mainly to help you practice. It is separate from osu! and does not aim to be a perfect copy. The client supports only osu!(standard) beatmaps; difficulties for other modes, such as mania, taiko and ctb, are not shown.

Practice tools

You can change beatmap settings such as Approach Rate, Circle Size, Overall Difficulty and HP Drain, adjust speed or BPM, and jump to any point in a beatmap using scrubbing. Quicksave and quickload are also available. Mods and options can be changed during play, and the client includes a live pp counter, a ranking screen and customizable HP Drain and Notelock algorithms.

Modes and customization

The client offers a VR mode and a first-person 3D mode called FPoSu. Experimental mods include Wobble, Jigsaw, First Person, Playfield Flipping and Reverse Sliders. Options and console commands allow extensive customization, and skins are supported through Steam Workshop.

Beatmaps and profiles

If osu!(stable) is installed, McOsu can load beatmaps from its default installation path; custom paths are also supported. The client can be used without osu!(stable), though that is not recommended. It also includes unlimited offline profiles with pp rankings.
