PowerBeatsVR just got another major update with a special new feature: You can now play with your own music library and let the game auto-generate suitable workouts on all three difficulty levels! And if you want to change the workouts to stress specific parts and adapt them to your needs, you have the options for that.
But there is more. The level editor is now much easier to use and there are new features, such as an additional strength and activity bonus, an indicator for the direction to punch multiple targets in a row, the option to choose between curved and straight flight paths for incoming objects, and several game modifiers, amongst them a “Super Speed” modifier: Steamcommunity.com
