Lasers, bombs and bullets hit on the beat of your music. Play songs from osu!, Beat Saber, Geometry Dash or any mp3 – FLUX turns them into maps.

What's in FLUX

Easy to learn, hard to master. Every attack lands exactly on a note of the song.

♫

Your music

FLUX finds your osu!, Beat Saber and Geometry Dash songs by itself. Drop any mp3, ogg or flac into the songs folder, or import .osz files.

!

Rhythm maps

Patterns follow the beat: "bam – ba – bam", not random. Everyone gets the same map for the same song, so scores are fair.

Mods

Double Time, Half Time, Hidden, Shifty, Rotate, Mirror, Sudden Death and NoFail – mix them for more points.

✎

Map editor

Place lasers, walls, spinning lasers and homing bullets on the beat. Share songs + maps with friends as .fluxmap.
