Defeat the Beat has 2 main components. Recording and Playing, both done in game in VR. You can search for a song and record your movements to the song. After recording or downloading beat maps you can try for a highscore against the boss as it sends attacks at you in the exact way the song was recorded.
Recording
Creating beatmaps are done entirely in VR
Search for any video on YouTube to record to
Use 4 different weapons (Shield, Sword, Blaster, and Bow) to create a beatmap to however the song makes you feel
Currently songs are saved locally and the files do not contain any copyrighted information so they can be shared outside the game legally
Playing
Face off against the beat - and try to match the moves of the beatmap's creator
Record your highscore locally
Weapons automatically switch to whatever is needed at the time so you can focus on hitting the beats.
